Rougher Flotation Cells Crushers, Ball Mills, Flotation
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.

Froth flotation
Before froth flotation can work, the ore to be treated is reduced to fine particles by comminutionso that the various minerals exist as physically separate grains. This process is known as fullliberation. The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes are depleted and replaced by ore bodies th
