Process flow-sheet for gold and antimony recovery from

2000. 10. 1. Recovery of gold from refractory ores requires a pretreatment to liberate the gold particles from the host mineral. In particular, in the case of stibnite (Sb2 S 3), the antimony (Sb) forms stable compounds with sodium cyanide (NaCN) during the cyanidation process; as a consequence, cyanide consumption increases.

A selective process for extracting antimony from refractory

2017. 5. 1. The clean production process for extracting antimony from refractory gold ore involves sodium sulfide leaching, pressure oxidation, concentration, and crystallization steps. First, the stibnite in the refractory gold ore reacts with sodium sulfide, and antimony is dissolved into the leaching solution in the form of sodium thioantimonite (Eq.

Leaching of Antimony from Stibnite Ore in KOH Solution

2021. 1. 13. This work aims to shed light on the leaching kinetics of antimony from stibnite ore in potassium hydroxide (KOH) solution. Response surface methodology based on central composite design was used to investigate the effect of time, temperature, solid to liquid ratio (S/L), and KOH concentration as independent parameters on the leaching efficiency of antimony.
