Purpose of the development: Preparation of magnesium and calcium-containing materials.

Recommended application field: Chemical Technology.

Advantages over analogues: Schemes put forward by consistent economic and environmental requirements.

The development stage readiness: Ready for application

Description of the development:
()
The first scheme - hydrometallurgical processing of dolomite ore complexion in a closed cycle using acid leaching agents. Allocation of valuable components in the form of commercial products can be thermal, chemical and electrochemical methods. The proposed flow sheet provides a mode of counter-leaching. As a commodity-products of dolomite ores can be obtained from: MgSO2, Mg (OH) 2.MgO, Mg, CaSO4 (gypsum). Na2CO3 (soda ash), NHCO3 (baking soda), (NH4) 2SO4 (fertilizer). The second scheme - the hydrometallurgical processing of dolomite with the use of underground leaching of acid corresponding to the economic and environmental requirements and differing technological simplicity. The processing of dolomite under this scheme as commercial products can be obtained: Mg (OH) 2, MgO, Mg, CaO.
