In earlier practice, the tailings of many gravity plants were of a higher grade than the ore treated in many modern flotation plants. Warranting its own history (Lynch et al., 2010), at least one technology historian has described flotation as "perhaps the greatest single metallurgical improvement of the modern era" (Mouat, 1996).

Copper content in the ore feed, collector dosage in the rougher and the scavenger flotation circuits, slurry pH in the rougher flotation circuit and frother consumption were selected as input parameters to estimate the copper grade and recovery of final concentrate, as well as the copper content in the final tailings of the flotation plant.
Because of the presence of acid-consuming minerals in the ore, the flotation scheme devised for the anorthositic platinum-palladium ore was not satisfactory for the serpentinized ore. To obtain the desired pulp pH of 3.7 for acid circuit flotation, an excessive amount of sulfuric acid (92.5 lb per ton of ore) was required.
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. ... In 1950s, the direct flotation route was integrated in plants, including Humboldt Mine (USA, 1954 ...
Conventional flotation plant optimization procedures for copper and copper–gold ores have served the industry well over decades. But with the present trend in declining ore grades along with increase in metallurgical complexity, many flotation operations are experiencing significant challenges in sustaining design or operational budgeted recovery and concentrate …
