Concentration - Mineral Processing

The flotation method is based on the difference in the physical and chemical properties of the mineral surface, processed by the flotation agent, and the mineral is selectively attached to the bubbles to achieve the purpose of separation. Non-ferrous metal ores, such as copper, lead, zinc, sulfur, and molybdenum, are mainly treated by flotation.

Mineral Processing - an overview ScienceDirect

The processing of lithium-containing minerals such as spodumene, in general, comprises crushing, wet grinding in a ball mill, sizing, gravity concentration, and flotation using a fatty acid (oleic acid) as the collector. The major lithium mineral in lithium ore is spodumene, which is considered insoluble in water and dilute acids. However, a small amount of dissolution may occur during processing of the ore
