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.

Yantai Rhyther offers gold ore mineral processing EPC services for Sudan Company. The mine’s daily processing capacity of ore is 500 tons, by the Rhyther laboratory for the determination of ore properties, mineral processing experiments, get the following conclusions: the ore is gravity tailings, metal minerals accounted for 3% of crude ore, non-metallic minerals accounted for 97%, recyclable metal for gold and a small amount of silver, gold in the gangue minerals in fine particles and ultrafine particles, gold grade 7.22g / t, silver grade 4.58g / t, leaching rate of 93.12% by the cyanide leaching.

The main configuration of the plant includes:

Gravity separation tailings by the forklift into the ore warehouse, transported by a belt conveyor to a round vibrating screen, in addition to impurities. And then transported by the belt conveyor to the powder ore storage.

Grinding grading process: the use of two-stage closed-circuit grinding process, the ore grain size reached -200 mesh accounted for 90.0%, and then cyanide leaching. Qualified grain size before the debris and then into the concentrator for concentration.

Cyanide leaching gold extraction process: cyanide leaching carbon adsorption process, designed 7 leaching adsorption, the entire consumption of low doses, access to higher leaching rate. Activated charcoal from the last slot to join, and gradually move forward a slot to get a certain grade of gold charcoal, the charcoal will be added.

Desorption and electrowinning system: adopt high temperature high pressure desorption electrowinning without cyanide technology, with high desorption rate. Send the full load gold-loaded carbon to the circle, first to the desorption column , the pregnant liquid sent to the electrowinning cell, to get gold mud, the desorption liquid will be recycle use.

Smelting process: The use of wet smelting process, in conjunction with the fire process, the electrolysis after the gold mud into the smelting workshop, will get 99.9% gold.

Tailings discharged directly: After tailings sedimentation experiments, sedimentation effect is ideal, the ore tailings discharge processing;The tailings water direct return system, no wastewater effluent, achieve the goal of energy conservation and emissions reduction.

Yantai Rhyther offers gold ore concentrator EPC services for the Sudan River Nile province. The mine’s daily processing capacity of ore is 1500 tons, by the Rhyther laboratory for the determination of ore properties, mineral processing experiments, get the following conclusions: the ore is gravity tailings, metal minerals accounted for 3% of crude ore, non-metallic minerals accounted for 97%, recyclable metal for gold and a small amount of silver, gold in the gangue minerals in fine particles and ultrafine particles, gold grade 7.23g / t, silver grade 4.58g / t, leaching rate of 93.21% by the whole mud cyanide gold.

The main configuration of the plant includes:

Re-election tailings by the forklift into the ore warehouse, transported by a belt conveyor to a round vibrating screen, in addition to impurities. And then transported by the belt conveyor to the powder ore storage.

In the whole process of the implementation of the project, Rhyther’s important principles: comprehensive planning, rational distribution, protection of the environment, safe production, strict control of the construction cycle, to provide customers with high-quality plant turnkey service, and get the customer’s approval.

Grinding grading process: the use of two-stage closed-circuit grinding process, the ore grain size reached -200 mesh accounted for 90.0%, and then cyanide leaching. Qualified grain size before the debris and then into the concentrator for concentration.

Cyanide leaching gold extraction process: cyanide leaching carbon adsorption process, designed 8 leaching adsorption, the entire consumption of low doses, access to higher leaching rate. Activated charcoal from the last slot to join, and gradually move forward a slot to get a certain grade of gold charcoal, the charcoal will be added.

Smelting process: The use of wet smelting process, in conjunction with the fire process, the electrolysis after the gold mud into the smelting workshop, will get 99.9% gold.

Tailings dry discharge: Because the mine muddy is serious, there’s higher mud content, after the leaching of the tailings first into the mixing tank, adding flocculant, to a certain concentration, transported to the belt vacuum filter, the solid-liquid separation, get less than 20% moisture dry ore. Filtrate recycling, to achieve zero discharge of sewage.

Rhyther offers a plant turnkey engineering service for a gold mine of Tanzania, , once again confirms the professional and strength of Rhyther. The mine is a gold mine re-election tailings, by the Rhyther laboratory for the determination of ore properties, mineral processing experiments, get the following conclusions: The main metals are natural gold, pyrite, chalcopyrite, hematite, copper blue, malachite and so on. The sample contains gold 0.68g / t, copper 0.265%, which is the main recoverable metal elements in the ore, iron grade 14.30%, other metal elements content is very small, in addition to copper and gold, other metal elements do not have the value of recycling. Ore oxidation is higher.

The main configuration of the plant includes:

Grinding and classification process: Two sections of a closed-circuit grinding grading process, the mineral reached -200 mesh accounted for 65%, to float the particle size, comprehensive recovery of ore in the useful gold and copper.

Flotation process: the entire flotation with a rough selection, two sweep, three selected, gold recovery rate of 91.08%, copper recovery rate reached 64.74%.

Concentrate and tailings dehydration: According to the Rhyther laboratory on the concentrate with the tailings of the test analysis, concentrate and tailings are carried out a concentration, a filter process to control the concentrate and tailings moisture content of less than 20% , which achieve tailings dry discharge. Part of the election plant water recycling, to achieve the gold ore flotation concentrator zero discharge of sewage.
