The Institute of Mineral Resources and Utilization of the Chinese Academy of Geological Sciences uses a gold carrier transfer separation process to separate and concentrate high-sulfur carbon-containing fine-grained refractory metallurgical ores and low-sulfur arsenic-containing or carbon fine-grained refractory ores.

This process is a new technologically advanced and economically reasonable method for processing refractory ore deposits with low grade and high yield of conventional concentrates. It can be used as a process for retrofitting of existing concentrators and for the evaluation and development of mineral deposits of the same type of gold deposits. in accordance with.
The basic principle of the carrier transfer separation process is to use a strong adsorption of gold minerals to achieve the gold carrier transfer, and adjust the electrochemical conditions of the slurry and control the oxidation state of the mineral surface through flotation agents, resulting in new carrier minerals (from carrier and different carrier minerals) Larger flotation differences with the older carrier minerals.
The carrier transfer separation process can significantly increase the gold concentrate grade of refractory metals ore, reduce the content of harmful impurities, and provide better raw materials for smelting. For high-sulfur carbon-containing fine-grained gold ore in Dongbeizhai, the conventional flotation can only yield 23.42% yield and 28.65g tons of gold concentrate. After adopting the carrier transfer separation process, the yield can reach 8.32% and the gold grade can reach 73.85 grams of gold concentrate, with 61.45% of sulfur removed. For the low-sulfur arsenic and carbon fine-grained gold ore of Sichuan Yinhe, the conventional flotation yielded a concentrate with a yield of 50.86% and a gold grade of 7.75 grams. After the heterogeneous carrier transfer separation process, a yield of 14.35% and a gold grade of 21.45 grams were obtained. The gold concentrate reduced the yield by 96.80% and removed 96.80% of sulfur and 89.53% of arsenic and 72.58% of carbon in conventional concentrates.
For the high-sulfur carbon-containing fine-grained gold ore, the use of self-carrier transfer separation technology will increase the annual profit of 156,500 to 171,600 yuan per 10,000 tons of processed ore. For the low-sulfur arsenic-containing, carbon fine gold ores, different carrier transfer and separation technologies are used. Each year, 10,000 tons of primary ore are used for an annual increase of 989,400 to 1,303,100 yuan. It also has good environmental and social benefits, and has extensive promotion. Value.
