The Stibnite Gold Project Midas Gold

The Stibnite Gold Project is unlike any other mining project. We have located a worldclass deposit of gold and antimony in an area in need of serious environmental repair. Our project can help the environment and leave the area better than it is today. We can correct the damage of the past.

A selective process for extracting antimony from

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

How Antimony is Processed by Flotation

The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore.The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of quartz but contains, in addition, a small amount of talc.

Antimony Wikipedia

Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.

Antimony Smelting Mineral Processing Metallurgy

China now leads the world in antimony production, having contributed during recent years something over 60 per cent, of the worlds production. The history of the antimony industry of China dates back to 1897 when the Tai Shing Co. was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude and in 1908 the Wah Chang Mining Smelting Co. was formed for

Gold parting Wikipedia

The antimony process is the same but uses stibnite (Sb 2 S 3) instead of sulfur because stibnite is stable at a higher temperature than sulfur. This is much quicker than the salt process and gave a purer gold, but it could dissolve some of the gold as well. This process is first

Process flowsheet for gold and antimony recovery from

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 (Sb 2 S 3), the antimony (Sb) forms stable compounds with sodium cyanide (NaCN) during the cyanidation process as a consequence, cyanide consumption increases.Pretreatment is usually an oxidation step.
