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.

Sep 12, 2017· The ore is milled quartz breccia with free gold and stibnite, all other minerals/elements are negligible. The stibnite content is pretty high and it is dissolving in aqua regia and precipitating when I add the sodiuim metabisulfite. How would I separate the antimony from the aqua regia before the gold.
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 .
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.

Only gold, antimony, and silver ores were mined in the Meadow Creek mine, which was ... the gold ore bodies, and the third and final stage by replacements by stibnite and silver ..... oxidized state is small no attempt is made to recover it.
Remember this material is old flotation''s tail of stibnite with gold values. This material is old flotation tail of Stibine with gold values (maybe the head''s flotation in plant was 8% Sb or more). We want to gold recovery by flotation (now we have a recovery 70% of gold) then maybe roasting tests to finally cyanidation and recovery gold.

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.

GEOLOGY OF THE TUNGSTEN, ANTIMONY, AND GOLD DEPOSITS NEAR STIBNITE, IDAHO By JOHN R, COOPER ABSTRACT The deposits of tungsten, antimony, silver, and gold described in this report occur in an area about a mile wide and 3% miles long near the town of Stibnite, Valley County, Idaho. Ore has been mined from only two deposits in the area,

Antimony is sometimes found in pure form. It also is obtained from the mineral stibnite (antimony sulfide) and commonly is a by ...
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 ...
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.

Ubaldini et al. used alkaline sulfide leaching as a pretreatment step, to remove antimony from a goldbearing stibnite ore. Antimony was then recovered by electrodeposition. Results showed that this pretreatment improved the recovery of gold in the consequent cyanidation process from 30 to 75 %.
