Introduction to Mineral Processing

Introduction to Mineral Processing

Introduction to Mineral Processing. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.

USA Column flotation method Google Patents

A method for the beneficiation of mineral ores by the flotation method whereby a slurry is introduced under pressure into the top of a first column through a downwardly facing nozzle, and air is entrained into the slurry forming a downwardly moving bed in the first column. The bed passes from the bottom of the first column into a second column where the froth and liquid separate, the ...
