USA - Flotation of copper sulfide ores with ...

High-purity dialkyl thionocarbamates are economically produced by reacting suitable xanthates with alkyl amines in the presence of a dissolved catalyst. Nickel and palladium salts are preferred catalysts. Thionocarbamates produced by the method of the invention are a desirable flotation reagent for certain refractory copper sulfide ores.

Copper Sulfide Ore Flotation Technologies - Xinhai

Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as "collect early, loss early" and "more crushing and less grinding".FLOTATION OF COPPER AND NICKEL SULFIDES FROM TALCOSE ...Oct 10, 1972· What I claim as my invention is 1. A process for the flotation of nickel and copper sulphide minerals from talcose bearing ores comprising producing an alkaline pulp of the ore in a suitable state of subdivision for flotation wherein at least one alkaline reagent present is soda ash or ammonium hydroxide and the pH is within the range of from about 8 to about 10.5, conditioning the .

PH ADJUSTMENT TEST OF COPPER/LEAD BULK FLOTATION The flotation of the polymetallic sulfide ore of copper, lead, and zinc is generally suitable at alkaline pH conditions. Lime and soda are common agents used in adjusting the pH of the slurry. These agents were used and the effects ofCopper Sulphide Ore Flotation Process - XinhaiCoarse-grained copper sulfide ore can use a stage grinding – a stage floatation process, and the fine-grained copper sulfide ore can adopt two stage grinding- two stage flotation process. What's more, middling regrinding technology can reduce grinding energy consumption, which is widely used in ore dressing production.
