Introduction to the experimental research status of gold ore dressing equipment for concentrate removal technology

China’s gold mine beneficiation has a long history of development, but modern production methods have not yet been fully popularized. The increasingly developed beneficiation equipment and beneficiation technology have also put forward higher requirements for the management and development of beneficiation manufacturers. Take a gold beneficiation manufacturer in China as an example. Take a look at the current development of mineral processing technology in China’s gold beneficiation mines.

The current development of mineral processing technology in China’s gold beneficiation mines.

Most of the gold-bearing ore of a Chinese company is a fine-grained, hard-to-select and difficult-to-leaching gold ore. After chemical element analysis and technological mineralogy research, it is found that this part of the ore has a remarkable feature that a part of the gold exists in the form of fine particles and packages. In the crystal lattice of pyrite or arsenopyrite, traditional cyanide leaching cannot effectively recover the gold in it. Therefore, the intelligent use of a combined process can maximize the recovery and utilization of this difficult-to-treat gold resource. Incorporating the pretreatment process into the original process of the enterprise and pretreating the gold concentrate by itself to realize the production of gold is a better way to improve the entire process, reduce production costs and increase the efficiency of the enterprise. Let’s take a look at how to develop and research gold concentrate de-drugging technology in the entire improved process.

Gold concentrate de-drugging technology in the entire improved process

The concentrate slurry after flotation enrichment contains a large amount of flotation reagents, which need to be removed before entering the biological oxidation, otherwise a large amount of residual flotation reagents will be brought into the biological oxidation, which will aggravate the oxidation tank The phenomenon of troughing further affects the next production process. In the original design process, the flotation gold concentrate is first subjected to preliminary thickening and demedication through the thickener, and the thickened slurry is again subjected to pressure filtration and demedication to remove the flotation agent in the gold concentrate. Remove as much as possible. However, because the ore contains a large amount of clay minerals, the viscosity of the ore is relatively high, and the ore is difficult to settle. Therefore, a large amount of flocculant is added during the settlement of the ore. The daily processing capacity of the filtration and drug removal section is far lower than the normal production requirements, and cannot meet the processing capacity of biological oxidation. At the same time, due to the high water content in the filter press cake, the residual amount of flotation agent entering the oxidation tank still causes a large number of bubbles on the surface of the oxidation tank slurry, and the effect of the press filter to remove drugs is not ideal. After research, it was decided to remove the entire section of the press filter demedication process. The bubble generation caused by the residual flotation agent was solved by the oxidation tank defoaming system. The adoption of this measure avoided the difficulty of press filtration of the concentrate and ensured the production capacity. The process is stable and smooth.

Significance of The research and development of concentrate de-drug technology

The research and development of concentrate de-drug technology is very critical in the entire beneficiation process. The future development direction will also rely more on biological science and technology to benefit the healthy development of the environment and economy. It has both economic and social significance and is very worthwhile. Vigorously promote and popularize.
