Nickel ore can be divided into copper sulfide nickel ore and nickel oxide ore. Flotation is the main beneficiation method when processing copper sulfide nickel ore, and magnetic separating and gravity separating are the commonly auxiliary methods. ...
Adopting mixed flotation-concentrate regrinding process can reduce the grinding cost, and be easy to manage. Application of new non-toxic flotation reagents is efficient and environmental protection. ...
Gold CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, the CIL process lowers the gold mining operation cost and increases the gold recovery rate to 99%, which is the first choice of modern gold mining and gold beneficiation plant....
Gold CIP process adsorbs gold from cyaniding pulp by active carbon including 7 steps: leaching pulp preparation, cyaniding leaching, carbon adsorption, gold loaded carbon desorption, pregnant solution electrodeposit, carbon acid regeneration, and leaching pulp....
The silver flotation process of Xinhai includes three kinds of methods: flotation, flotation & gravity separation, flotation &cyaniding. While the flotation &cyaniding method is the most important process among the three. The silver concentrate can get in the process of flotation, then regrinding to the next process including cyaniding and leaching, countercurrent washing, zinc powder replacement, and silver ingot can finally get after the last process of electrolytic dissociation. Thus the process is characterized by high recovery and economic benefits....
Heap leaching (HL) is a flexible and economic gold ore processing method used to extract gold from low-grade gold ores. In this process, the ore is firstly crushed to fine particles. By spraying the leaching solution to the large piles, the gold-containing solution is leached. Then used the gold processing method of carbon adsorption, zinc powder displacement device, and so on to separate gold from the liquid....
Alluvial gold processing solution mainly applies to processing alluvial gold with a large volume of gangue minerals. Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc....
Flotation is widely used in gold processing. In China, 80% rock gold is processed by flotation. Flotation process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged. Flotation in gold mine has low beneficiation cost....
