precipitation for antimony ore

Fluid inclusions and ore precipitation mechanism in the ...

Apr 01, 2018  The precipitation of early gangue minerals resulted from fluid boiling caused by an abrupt drop in pressure, and fluid mixing was responsible for the subsequent stibnite precipitation in the ore district. (4) The Xikuangshan deposit is re-classified as a typical mesothermal deposit, rather than an epithermal one as previously considered.

The ore mineral assemblages include early-stage quartz-stibnite, fluorite-quartz-stibnite and barite-quartz-stibnite, and late-stage calcite-stibnite. In spite of numerous research works on the Xikuangshan deposit during the past several decades, the signatures of the ore-forming fluids and the ore precipitation mechanisms are poorly constrained.

Precipitation Process. a refining process in which the sulfides of a metal ore react with a precipitating agent—metallic iron. The precipitation process is the most commonly used method for refining antimony ores in the USSR. Antimony is reduced by iron in the reaction Sb 2 S 3 + 3Fe = 2Sb + 3FeS, which at 1000°-1100°C is an irreversible ...

Scorodite precipitation in the presence of antimony

The effects of Sb on the precipitation of synthetic scorodite, and the resultant phases formed, were investigated. Nine synthetic precipitates with varying concentrations of Sb, together with As-only and Sb-only end members, were prepared using a scorodite synthesis method, and these were characterised using XRD, SEM, chemical digestion and μXRF mapping.
