Magnesite enrichment by a dry method

Results are provided for enrichment of low grade magnesite of the Satkinsk deposit (MgO 43.1%, CaO 4/07%, SiO 2 , Δ m calc 50.6%) by electric separation. The concentrates 1 and 2 obtained contain 96.9 and 97.1% MgO, 1.32 and 1.36% CaO, and 0.16 and 0.19% SiO 2 respectively. With enrichment of calcin...

Description
Summary:Results are provided for enrichment of low grade magnesite of the Satkinsk deposit (MgO 43.1%, CaO 4/07%, SiO 2 , Δ m calc 50.6%) by electric separation. The concentrates 1 and 2 obtained contain 96.9 and 97.1% MgO, 1.32 and 1.36% CaO, and 0.16 and 0.19% SiO 2 respectively. With enrichment of calcined magnesite by electric separation the concentrates 1 and 2 obtained contain 97.3 and 97.09% MgO respectively with a dry overall yield equal to 38%. The starting periclase powder contains 95.5% MgO.
