Abstract. The dephosphorization of manganese ores and concentrates in a reducing atmosphere is thermodynamically analyzed. It is shown that phosphorus can completely pass to a gas phase in a closed reaction system in a wide temperature range (1000–1800C) at the amounts of a reducing gas (CO) that exceed the stoichiometric minimum required for reduction reactions.

Advantages Reduction in Silica and Alumina content in washed ore by 0.5 1 over the existing levels Reduction in residual water in the product thus by reducing the transportation Beneficiation Of High Silica Manganese.

Reduction of chromite by graphite with CaO-SiO2 fluxes. Experimental studies were conducted on the effect of a combination of lime and silica fluxes on the carbothermic reduction of chromite. It was found that silica had a negligible effect on the reduction kinetics at 1325C.

of the concentrate (for removing silica) followed by reverse osmosis of the lime-treated water. Results showed that the membrane processes could reduce the concentrate volume by up to 55 percent, but at recoveries greater than this, membrane fouling was observed. Lime treatment of the concentrate was shown to be very effective for removing silica,
