magnetic separation sulfided


Separation Process and Method-Ore Beneficiation-

Separation is the main step of ore concentration. Metal recovery and productivity largely depend on the separation process and methods. Based on the physical and chemical properties of ore like its grain size, shape, color, density, friction coefficient, magnetism, moisture and electric property, several process and methods are available.

Magnetic separation of metal sulfides/oxides by Fe3O4 at ...

Magnetic separation of different metal sulfides/oxides with Fe 3 O 4 in aqueous solution. All the metal sulfides/oxides (WS 2, CuS, ZnS, MoS 2, CdS, TiO 2, MoO 2 and ZnO) used in the experiments are non-magnetic. As shown in Fig. 1, no magnetic separation of any metal sulfide/oxide was observed without Fe 3 O 4 added in aqueous solution. However, when Fe 3 O 4 was added, the …

Roasting (metallurgy) - Wikipedia

Roasting is a process of heating a sulfide ore to a high temperature in the presence of air. It is a step in the processing of certain ores.More specifically, roasting is often a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth ...
