Siderite Recovery

Siderite Recovery

Mainly copper skarn ore and copper-bearing magnetite ore, copper minerals are mainly chalcopyrite copper, sulfur minerals are mainly pyrite, iron minerals are magnetite, siderite, hematiteand so on.

Metallic minerals in the tailings siderite, hematite, magnetite, pyrite, chalcopyrite, and gangue minerals are quartz, chalcedony, garnet, calcite, dolomite and so on. Mineral dissemination size and monomer solution from the analysis of the degree-0.074mm grain size accounted for 69.5%, about half of the iron minerals and gangue minerals Liansheng siderite with silicate veins The minerals are even born.

Hematite and silicate minerals and carbonate minerals are even born. Magnetite more with quartz and chalcedony minerals with students, their relationship is complex disseminated. Determination of magnetic minerals in the tailings and its content is about 1%.

Siderite Recovery Process

Reverse flotation for sorting quartz, silicate or other gangue mineral content of less iron ore or crude concentrates, it is the use of quartz or silicate with magnetite, hematite natural Flotability the differences in the anti-flotation. in addition, a variety of fatty acid flotation in neutral and alkaline slurry is flotation, but did not achieve the purpose of sorting.

Directly get to the mine by a roughing the iron ore concentrate, roughing conditions: magnetic field strength 240kA / m, ore concentration of 33% rinse water 1.08m3 / h, the separator plate speed 4r/min backlash 5mm, income iron ore concentrate iron grade 43.54%, 15.49% iron recovery.

To the mine by the magnetic rougher, coarse concentrate regrinding selection, roughing magnetic field strength 1008kA / m, ore rate of 192kg / h, to mine the concentration of 40%, wash water 0.36m3 / h, the magnetic machine disk speed 4r/min backlash 5mm. And then pulverized-0.043mm grain size accounted for 79.51% of the selected magnetic field strength 400kA / m rinse water 1.08m3 / h, the proceeds of iron ore concentrate iron grade of 43.40% iron recovery was 32.85%.

Directly after the magnetic rougher magnetic selection proceeds of iron ore concentrate iron grade of 44.20% iron recovery 29.91%.
