Antimony separation process - Sunshine Mining Company

An antimony recovery process is disclosed in which antimony-containing material is leached in a solvent including elemental sulfur and a caustic to preferentially leach antimony. The antimony-containing leach liquor from the leaching step is separated from the insoluble residue by filtration, and the antimony compounds in the separated leach liquor are crystallized to separate the antimony ...

Sulfide Minerals - an overview ScienceDirect Topics

The ore-forming hydrothermal fluids for VMS deposits were reduced, high-temperature (up to 400 °C), seawater-dominated solutions that leached metals and sulfur from the underlying volcanic rocks (Fig. 2). The fluids were mobilized by large convective hydrothermal systems driven by the heat of subvolcanic magma or cooling intrusions, and the metals and sulfur were deposited by mixing of the ...

Separation and Recovery of Antimony from High Arsenic ...

The recovery of antimony from high arsenic-bearing flue dusts was carried out by a selective oxidation roasting process using MnO 2, in which the arsenic was removed through a volatilization and antimony was oxidized to Sb 2O 4 staying in the roasted products. In a certain range, the MnO 2 additive has an active effective on the arsenic volatilization for the reason that structures of some ...
