platinum ore, for instance, may require 45 minutes to an hour to reach completion and thus the first concentrate can be collected after two minutes of flotation. A faster floating copper porphyry flotation test, however, may finish in five minutes and a first concentrate may need to be collected after 20 seconds.

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.
