antimony ore extraction process :

A selective process for extracting antimony from ...

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.

Extracting antimony from high arsenic and gold

2019-6-1  The complex As-Au-Sb ore is also an important antimony resource that is predominantly mined in Hunan and other places in China. It is essential to develop an economical and environmentally friendly process for the extraction of antimony from this ore. Antimony production involves hydrometallurgy and pyrometallurgy, the latter being still dominant.

Metal Extraction Process for High Grade Stibnite of Kharan ...

A rapid and simple process has been developed for the recovery of antimony metal from stibnite ore of Kharan area (Balochistan) of Pakistan. The ore was characterized by X-ray diffraction (XRD) technique and found to contain 66% stibnite i.e. antimony sulfide (Sb2S3). The process parameters for the extraction of antimony were optimized on laboratory scale by varying reaction temperature from ...

Extraction of Antimony

Extraction of Antimony. Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or ...

Antimony Mineral, Extraction of Antimony, Antimony

Proportion of antimony ore is far greater than proportion of gangue, so it will be separated by using the method gravity separation. This method has many features, high efficiency, energy saving, and environment protection, which can make the low-grade ore enrichment advance. After gravity separation, the antimony will be purified by floatation.
