Froth Flotation Process

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.

Adverse Effects of Ore Slime and How to Solve Them

4) Preliminarily treat the ore with a collector, and then perform flotation. 5) Prioritize flotation of slime and sulfide. We can use ethanol or pine oil for the flotation of slime and use sulfhydryl collectors for the flotation of gold and sulfide. Normal Condition. In addition to the above targeted methods, we can also directly deslime the ore.

minerals. To finish the flotation process, the discharge from the second flotation step is dewatered again, and a cationic amine is used for collection as the feldspar is floated away from quartz in an environment of hydrofluoric acid (pH of 2.5 to 3.0). If feldspathic sand is the raw material, no size reduction may be required.
