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%.

Medium and low grade colloidal phosphate mineral particles are small and tightly embedded (Zhang et al., 2016), and have a high content of gangue minerals such as dolomite, quartz and iron-aluminum. In order to meet the requirements of wet processing of phosphorus, the beneficiation process is necessary.
Most of the mine water was saturated with major minerals, such as francolite, calcite, dolomite, aragonite, and fluorite, which might result from the water–rock interaction in phosphate beneficiation process. The unsaturation state of evaporite minerals, such as halite, gypsum, and anhydrite, indicated a low contribution of mineral–water ...
The beneficiation process begins with milling, which is followed by flotation for further beneficiation. At the first stage, extracted ores undergo the milling operation to produce uniformly sized particles for crushing, grinding, wet or dry concentration. The type of milling operable in a certain plant is chosen by capital investment and ...

process, a concentrate containing 78,14 MgO, 1,51% CaO and 0,55% SiO 2 was obtained, but the recovery in MgO was only 57,21%, while the feed content was 44.87% MgO, 3.1% CaO and 0,5% SiO 2. Suslikov et al. (1966) attempted to separate magnesite from dolomite by exclusively applying heavy media (gravity) separation.
Process mineralogy is the application of mineralogy knowledge to understand and solve problems in exploration, mineral processing, tailings disposal, hydrometallurgy, pyrometallurgy, and refining process [1,2,3].In mineral processing, it can be considered as the development and optimization of beneficiation process by …
