Oct 01, 2000· 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 is usually an oxidation step.

While roughly 100 tons of ore from mining shipped from Sliscovich in 1914 and 1915 contained about 35 percent antimony, the value of the gold and silver in this ore outweighed the critical mineral. "Antimony is often a highlevel indicator of deeper gold deposits," said Barker.

A mixture of nitric and tartaric acid [17] was used in the present work to decompose the stibnite ore sample. This method was proposed by Hampe [18] and has found wide application in the analysis of minerals containing antimony and tin, as well as of metallurgical products. Thus, tartaric acid is used mainly for the analysis of antimony ores.

Feb 02, 2015· Most antimony ore and thus research conducted is on Stibnite. Since Stibnite is a sulfide then floatation is the best way to go. Other minerals associated will determine reagents used and your complete flowchart. Standard reagents are MIBC, PAX, Lead Nitrate, and a .
The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony 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 .
The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment, realgar, and stibnite is usually difficult or even impossible. Extractions are low and the solutions soon become ''foul.'' The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected.
The rate of oxidation of stibnite is strongly dependent on pH with appreciable dissolution at pH 12, reducing to low levels at pH 10. Figure shows Hedley and Tabachnick''s (1958) results of the cyanidation of a synthetic ore containing % stibnite at pH values of 10, 11, and 12. At higher pH values, higher levels of antimony pentoxide have been observed on gold surfaces, which then ...
