Introduction to dolomite beneficiation process. August.20,2024. The mineral composition of dolomite ore is mainly dolomite, with a small amount of calcite, chalcedony, gypsum, hematite, clay and quartz. The average chemical composition of the ore is about MgO20.47%, SiO21.59%, acid insoluble matter 1.83%, phosphorus 0.06%. ...
