FROTH FLOTATION "So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined." The froth flotation process was patented by E. L.Sulman, H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests.
Copper production About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
Copper extractions from the copper smelter slag and the copper smelter slag flotation tailings as a function of time at different initial ferric iron concentrations By comparing Figure 2 and 4, it can be seen that both the copper extractions and
