Froth flotation | ore dressing | Britannica

Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral

Flotation Depressants - Mineral Processing & Metallurgy

First let’s change the amount of the Flotation Depressants used. The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral’s color. This is because the froth is becoming purer as ...

Use of humic substances in froth flotation processes ...

This approach could be implemented in froth flotation, the main process used to concentrate copper sulfide ores, by replacing the chemical reagents (i.e., collectors, frothers, and modifiers). These regents are used to control the particles’ superficial wettability and induce floatability over desired mineral selectivity ( Herrera-Urbina, 2003 ).

Copper Mining and Extraction Sulfide Ores

From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air.
