Abstract
A study of treatment of polyhalite ore was conducted by the method of washing halite using water as a washing liquid. The optimal conditions for washing halite from polyhalite ore (water consumption and temperature, contact time of the solid and liquid phases, ore grinding degree) were determined, providing the production of pure polyhalite and filtrate close to saturation with sodium chloride at low polyhalite losses.
