The gold ore processing plant is located in Mauritania and primarily focuses on reprocessing tailings. The ore has an average grade of 2 grams per ton, and the plant has a daily processing capacity of 800 tons. The gold recovery rate is 94%, resulting in the production of gold ingots with a purity of 99.99%. Rhyther team supplied the EPC service for this project, from mineral processing test, design, manufacture, installation, to training, Rhyter is responsible for the whole plant.

The process starts with the screening of the original ore, followed by two stages of grinding and classification, which achieve a particle size distribution of 90% passing 200 mesh. Subsequently, the material enters the concentration thickener, where it undergoes a process of concentration. After concentration, it enters seven leaching tanks, where leaching and adsorption occur simultaneously. The gold-laden carbon, after adsorption, is then transferred to a high-temperature and high-pressure desorption electrolysis system, where the gold is recovered through electrolysis.

The resulting gold electrolyte solution is then directed to a wet smelting system, where it undergoes further refining to obtain gold ingots with a purity of 99.99%. This wet smelting process ensures the production of highly pure gold.

The gold ore processing plant is equipped with advanced technologies and operates efficiently to maximize gold recovery while maintaining high purity levels. The plant adheres to rigorous quality control measures throughout the entire processing cycle to ensure the production of premium gold ingots.

With its state-of-the-art infrastructure and meticulous processing techniques, this gold ore processing plant in Mauritania stands as a leading facility in the region, contributing to the sustainable mining practices and the production of high-quality gold products.

1.The stage grinding and selection process is adopted

Because the technological process adopts the stage grinding and stage separation technological process, the technological process has a relatively economical beneficiation cost. After the first stage of grinding, classification is achieved under a coarser particle size. Under normal circumstances, about 60% of the coarse-grained concentrate and tailings can be extracted, which greatly reduces the amount of ore entering the second stage of grinding and is beneficial to reduce the concentration of ore. cost. At the same time, coarse-grained iron ore concentrate is conducive to filtration.

2.The selection is highly targeted

The dissociation of minerals in the grinding process is random. This process makes the mineral particles of different grinding sizes have dissociation conditions, which is one of the important foundations for the strong vitality of the coarse and fine selection process. Stage grinding, coarse subdivision, gravity separation → magnetic separation → anion reverse flotation process. The coarse grain grade after one stage classification is relatively good. A simple gravity separation process is adopted to select qualified coarse grain concentrates in time and discard the coarse grains. Grain tailings: The fine-grained grades after classification are relatively difficult to select, and the fine-grained tails are finely thrown by adopting the high-efficiency and relatively complicated strong magnetic → anion reverse flotation process. The effective combination of coarse-grained beneficiation methods and fine-grained beneficiation methods makes the process have the dual characteristics of economically reasonable and technologically advanced. At the same time, the gravity separation process to obtain a concentrate with a larger content and a coarser particle size is conducive to concentrate filtration.

3.Achieved narrow-level selection

In the process of mineral separation, the degree of choice of minerals is not only related to the characteristics of the mineral itself, but also to the specific surface area of the mineral particles. This effect is more prominent in the flotation process. Because in the flotation process, the flotation is related to the minimum value of the force between the beneficiation reagent and the mineral and the reagent and the bubble, the specific surface area of the mineral, and the ratio of the reagent to the mineral action area. This makes the factors affecting the floatability of minerals twofold. It is easy to cause minerals with a large specific surface area but relatively difficult to float and minerals with a small specific surface area but relatively easy to float to have relatively consistent floatability. Sometimes the former has even better floatability. Buoyancy. Realizing the beneficiation process of narrow grade selection can prevent the occurrence of the above-mentioned chaotic phenomenon that easily leads to the flotation process to a greater extent, and improve the beneficiation efficiency.

4.The efficiency of fine-grained sorting has been unprecedentedly improved

Stage grinding, coarse subdivision separation, gravity separation → magnetic separation → anion reverse flotation process, before the application of red iron ore beneficiation, the stage grinding process used for fine particle level is magnetic separation → acid positive flotation process, and the efficiency of ore dressing.It is very low, which affects the improvement of the technical indicators of the stage grinding and selection process. The fine particle separation process is changed from magnetic separation → acidic positive flotation to magnetic separation → anion reverse flotation process to form the current stage of grinding, coarse subdivision, gravity separation → magnetic separation → anion reverse flotation process. The selection index of the fine-grained grade has been unprecedentedly improved.

The characteristics of the continuous grinding, weak magnetic → strong magnetic → anion reverse flotation process are as follows:

Red iron ore:

1.Have a good process flow structure

Judging from the current status of red iron ore beneficiation in my country, strong magnetic separation is one of the most effective means of throwing tails, and anion reverse flotation is one of the most effective means to improve concentrate grade. At the same time, the combination of strong magnetic separation and anion reverse flotation is conducive to the realization of the complementary advantages of the technological process. This is not only reflected in the quality and tail reduction of the two processes itself, but also in that strong magnetic separation can provide good separation for reverse flotation Conditionally.

2.Convenient for production and stable operation

The continuous grinding process directly grinds the ore to a higher level of monomer dissociation, and uses a strong magnetic separator to remove the sludge and discard the tail. It not only prepares higher-grade selected materials for the anion reverse flotation process, but also eliminates the original. The influence of sludge and secondary sludge on the anion reverse flotation process, and the strong magnetic separation itself has good stability. Anion reverse flotation itself provides better candidates for its strong magnetic separation, and it also has better stability. Therefore, after the continuous grinding, weak magnetic → strong magnetic → anion reverse flotation process has controlled the final grinding particle size, the process has good stability and strong adaptability to ore, which is convenient for stable production and operation.

3.It has good process operation characteristics

Continuous grinding, weak magnetic → strong magnetic → anion reverse flotation process due to its high concentrate grade, low flotation temperature, suitable for pipeline transportation, good separation effect, good flotation foam stability, and good fluidity. Features, easy to control in production operations, which is conducive to the stability of production indicators. Of course, this process has the problem of high beneficiation cost due to the fine grinding particle size.

Introduction to Bauxite

Bauxite can be used in many fields, and the industrial utilization rate is relatively wide. The bauxite we are talking about is actually bauxite. Its main element composition includes gibbsite, boehmite and diaspore , The industry has a great demand for bauxite every year, but the bauxite beneficiation method is more complicated. Here is a brief introduction to the beneficiation process of bauxite.

Classification of bauxite

Bauxite, also known as bauxite, is generally a finely dispersed colloidal mixture composed of three minerals, diaspore, boehmite and gibbsite in various proportions. Bauxite often coexists with iron oxides and hydroxides, anatase, kaolinite, chlorite and other clay minerals. Sometimes it also contains minerals such as calcium, magnesium, and sulfur. Bauxite ore can be divided into high-alkali bauxite, high-titanium bauxite, and high-iron bauxite according to its impurities.

Beneficiation method of bauxite

The process of separating bauxite concentrate from bauxite ore is actually a process of removing gangue minerals and harmful impurities, separating high-aluminum minerals and low-aluminum minerals, to obtain a concentrate with a high aluminum-silicon ratio.

The main beneficiation methods of bauxite include ore washing, flotation, magnetic separation, chemical beneficiation, etc. Ore washing is the simplest and most effective method to increase the aluminum-silicon ratio of bauxite. Generally, washing the ore can increase the aluminum-silicon ratio of the ore by about 2 times, which is more effective for the sorting of loose texture ore. Ore washing is often combined with other sorting methods to form a washing (screening)-grading-hand sorting process.

The flotation method can be used to separate diaspore and kaolinite, using oxidized paraffin soap and tall oil as collectors, in an alkaline medium. Magnetic separation is used to separate iron-containing minerals. Chemical beneficiation mainly includes roasting and desilication. This is based on the fact that the main silicon-containing minerals in the ore are hydrous aluminosilicates. After roasting, part of the Si()z is transformed into amorphous silicon oxide particles that are easily soluble in alkali, which increases the aluminum of the material. Silicon ratio.

Choose method according to ore characteristics

Generally speaking, the main beneficiation process of bauxite will adopt different beneficiation processes according to different types of ore. For example, the beneficiation process of gibbsite-kaolinite bauxite usually adopts first mud and sand separation, coarse grade grinding and then magnetic separation for iron removal, and ore mud grinding and flotation. The flotation reagent is prepared with oleic acid, tall oil, and engine oil at a ratio of 1:1:1.

In fact, flotation is the most commonly used method for bauxite beneficiation, but for some accompanying organisms in bauxite that are not suitable for flotation, it is a different matter. So when you choose bauxite beneficiation technology, It must be determined according to the characteristics of the ore.

Fluorite ore is an important mineral resource, which plays a very important role in metallurgy, chemical industry and other industries and fields. As a mineral resource, fluorite ore can be used directly without treatment, so most of fluorite The ore needs to be processed and purified before it can be used. So what is the beneficiation process of fluorite ore? Yantai Rhyther Mining Machinery Factory is here to introduce the beneficiation process of fluorite ore for the reference of related parties!

The beneficiation process of fluorite ore needs to be formulated according to various factors such as the nature of the ore and the grade of the concentrate required by the customer. Generally, the beneficiation of metallurgical-grade fluorite concentrate only needs to be hand-selected and re-selected. For the acid-grade chemical industry The preparation of fluorite concentrate powder needs to be obtained by flotation. The process is a combination of manual separation, gravity separation, and flotation to process fluorite ore, which has a strong representativeness.

Brief introduction of fluorite beneficiation process:

1.Crushing and screening process

Fluorite is fragile and fragile. The crushing process adopts a simple jaw crusher to avoid excessive powdery fluorite ore. The screening adopts a circular screen with high screening efficiency and thorough screening, and the crushed products are strictly In the screening operation, the crushed fluorite ore is divided into three sizes: +30mm, 8-30mm, and 0-8mm.

2.Hand selection process

Hand selection means manual hand picking and discarding of large gangues, and picking out coarse-grained fluorite concentrate. Manual selection is generally carried out on a horizontal belt conveyor with adjustable speed, and qualified concentrates are selected by manual picking method.

3.The gravity separation

The gravity separation process uses a jig to center, and the fine-grained fluorite ore is gravity-dressed, and the granular concentrate is mixed with the hand-dressed concentrate as a coarse-grained metallurgical grade fluorite product. The tailings and hand-selected tailings are mixed into the grinding process.

4.Flotation process

Fluorite belongs to easy-float ore. The flotation process includes grinding, grading, flotation and other processes. The flotation of fluorite ore is mainly based on the separation of fluorite and gangue flotation. Fluorite flotation The collectors used are usually: fatty acids such as oleic acid or oxidized paraffin soap and their soaps as collectors, and the best flotation temperature is 30-35 degrees. Sodium carbonate is used as regulator and water glass as inhibitor during flotation, and the best flotation temperature is 30-35 degrees.

As acid-grade fluorite concentrate requires high grade, the flotation process is generally designed with multiple beneficiation processes, at least not less than 3 times of beneficiation. This process uses 6 times of beneficiation, and the grade of fluorite concentrate is guaranteed to be more than 97%.

The beneficiation process of fluorite ore needs to be determined according to the nature and purpose of the fluorite ore. For the beneficiation of coarse-grained contiguous fluorite, the method of manual separation and gravity separation is generally used to obtain metallurgical grade fluorite concentrate. The flotation method is generally used to prepare high-quality fluorite powder from fine-grained embedded low-grade fluorite ore.
