Gold recovery from the stibnite concentrate was in the range of 50–80%, dependent on the level of exposure in the concentrate treated. For most years, gold-rich arsenopyrite/pyrite concentrates from Hillgrove were sold to smelters. ... Low-Grade Antimony Gold Ores. For gold ores, where minor, economically insignificant stibnite …

Hi all, So over the weekend I tried to process my gold bearing ore with aqua regia and failed yet again. 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.

The headwaters of the East Fork South Fork Salmon River, and its importance to salmon recovery, are far too valuable to be placed in jeopardy at the expense of a profit driven gold mine. The Nez Perce …

At the plant of the Consolidated Murchison Co. in the Transvaal, South Africa, where a refractory high-antimony gold ore is being treated, flotation and cyanidation of the flotation concentrates and tailings are being practiced.
