One is that the one stage leaching process is replaced by a two stage leaching method, and the other is the combined leaching of jamesonite concentrate and high grade stibnite concentrate. The two methods can improve the antimony concentration in the leaching solution, reducing the consumption of 20% and 60% sodium sulfide, respectively.
Cyanide Leaching of Flotation Concentrate. When Charles Butters began to take up the work of flotation in our Oakland laboratory, one of the first points brought to our attention was the treatment of the concentrate produced by flotation; J. E. Clennell was accordingly instructed to undertake the researches detailed in the present paper.
A Flowsheet to recovery gold from sulfide ores. There are many arrangements and combinations using flotation in conjunction with treatment of gold ores. The two gold process flowsheets shown, with some variations, are probably the most commonly used. In Gold Flowsheet No. 1 the ore is ground in water to such a size as to free the minerals ...
The best flotation test results are given in Table ... Gravity separation is an effective method which has been applied to process many types ... Batch agitation leaching tests were conducted at ...
Agitated Leaching. Copper Agitated Leaching and cementation process of copper problem: The treatment of copper ores, both oxides and sulfides by means of flotation, hydrometallurgy or other processes has been well established for many years. Flotation has been applied generally to the treatment of sulfide ores, both in small and large scale ...
Flotation. The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the ...
