How to Conduct Lithium Ore Beneficiation Tests?

Due to the differences in the properties of the raw ore in each mining area, the flotation process for various ores is inevitably not the same. Before formulating the flotation process, it is essential to conduct beneficiation experiments to determine the reasonable values of different indicators and parameters in the flotation process.

Mining

The tanks, known as flotation cells, are agitated; this adds air, forming bubbles to which the hydrophobic minerals link. As a result, the minerals rise to the top of the cell. There, they collect in a launder. The ore that does not float is taken away as tailings, which may be subjected to further flotation.

Essential Guide to Mineral Processing & Equipment

Froth flotation. Froth flotation uses a chemical collector and frother that forms bubbles on the surface of the slurry that hydrophobic materials bind to. The bubbles are collected off the surface of the frother. Activators are used to enable the flotation of one mineral ore while depressants are used to inhibit the flotation of the gangue.
