Rougher Flotation Cells are usually placed on the beginning of the flotation circuit of mineral concentration process . In this stage the bulk of the gangue is removed from the ore. The aimed minerals will be concentrating in the froth.  These concentration froth will be sent into the cleaning flotation cells for getting the concentration with high grade of aimed minerals.

Rougher Flotation Cells

Rougher Cells will receive the feeding material flow from the ball mill.  So flotation cells in this stage have bigger working volume than the cleaner flotation cells and scavenger cells.

 

Rougher cells also have 2 types, mechnical agitation with self- absorbtion air cells and Pneumatic flotation cells.  Choosing the different type according to the features of the ores.
