The Role of Coarse Conditioning Drums in Potash Flotation
If necessary, potash ore goes through a size reduction and screening process to obtain the desired particle size range. Separation. Coarse and fine ore fractions are typically separated to maximize the efficiency of the conditioning and flotation processes. Fines may or may not be conditioned, but coarse ore is generally always conditioned.
