Application of gold mining equipment

I) Sand gold beneficiation equipment, sand gold ore dressing equipment crushing and grinding According to the survey, China's gold selection is mostly crushed by a jaw crusher, which is crushed by a standard cone crusher, while the fine crusher is a short-head cone crusher. And on the roller crusher. Most of the small and medium-sized gold-removing plants use two-stage closed-circuit crushing ore, and the large-scale gold-removing plant adopts a three-stage and one closed-circuit crushing process. In order to improve the sand gold beneficiation equipment, the mineral processing capacity of the sand gold ore dressing equipment, and the potential of the excavation equipment , the crushing process has been modified to improve the utilization coefficient of the grinding machine. The soil measures adopted are to implement multiple crushing and grinding, and reduce the grinding ore. granularity.

b) Sand gold beneficiation equipment, re-election of sand gold ore dressing equipment is widely used in rock gold mines, as an auxiliary process, recovering coarse gold in the grinding circuit, creating favorable conditions for flotation, improving beneficiation index, and improving gold The total recovery rate has played a positive role in increasing production and reducing wood.

3) Sand gold beneficiation equipment, sand gold ore dressing equipment Flotation According to the survey, about 80% of China's rock gold mines use flotation method to select gold, and the produced concentrates are sent to non-ferrous smelting. Due to the increasing development of cyanide gold extraction and the improvement of economic benefits and reduction of concentrate transportation losses, the product structure has undergone major changes in recent years, and more local treatment has been adopted. Of course, due to the contradiction between pricing and smelting. Such problems have forced the mine to handle it on its own, which has led to a great development of the flotation process and plays a very important role in gold production. There are usually two processes of preferential flotation and mixed flotation. In recent years, there have been new progress in process modification and pharmaceutical addition systems, and the flotation recovery rate has also been significantly improved. According to the survey of flotation process indicators in more than 40 gold selection plants across the country, the recovery rate of sulfide ore flotation is 90%. A few are as high as 95% and 97%; the recovery rate of oxidized ore is about 75%: 80% and 85% for individual. In recent years, there have been many innovations and research results in the flotation process, and the results have been obvious. The phase grinding process and the re-floating combined process are the main trends in the development of flotation process in China. For example, a gold mine in Hunan uses a re-floating combined process to carry out stage grinding.
