The tailing from average ore, when conditions for flotation are right, is 4.5 oz. silver per ton. The grade of tailing appears to be independent of whether the original ore is treated by flotation, or whether wet concentration precedes flotation. The alkalinity during flotation must be between 0.01 and 0.05 lb. per ton of solution.

Various flotation reagents are added to the pulp after grinding, and the pulp is stirred to make it to fully interact with mineral particles, so as to expand the floatability difference among different mineral particles. The adjusted pulp is transported into flotation equipment, and aerated and stirred to form the bubbles (Fig. 2). The ore ...

Flotation Process of Copper Sulfur Ore 1. Priority flotation. Generally, the copper is first, and then the sulfur is floated. The pyrite content in the ore is relatively high for massive copper-containing pyrite. High alkalinity (free CaO content >600~800g/m3) and high xanthate dosage are often used to suppress the pyrite by floating copper.
