The flotation is performed at a pH value of 8.5-9. The pH adjusters are sodium carbonate and sulfuric acid, which should be added in an appropriate amount in case of any flotation ing and stickiness. Then, the direct flotation or reverse flotation method is used to obtain concentrated fluorite. 2.4 Fluorite-quartz type ore

This installation was one of the first large plants to prove the value of flotation in the treatment of gold ores. At the outset, when the ore to be milled was mined at or near the surface, 80% of the values were recoverable by amalgamation, and a 90% recovery could be made by a simple amalgamation and table concentration process. ...

flotation models are linked. For example, a laboratory test conducted on a drill core sample, intended to represent a portion of the orebody, is conducted at a specific grind (represented by a P 80). However, when that ore is actually processed through the plant it may well be (and in many cases most likely will be) at another P 80 ...
