flotation separation plant

Froth flotation - Wikipedia

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 that were formerly considered too difficult. In the mining industry, the plants where flotation is undertaken to concentrate...
