(The temperature has reached 900°F. at the fifth port and rises slowly to a maximum of 1150° at the eighteenth port. Exit gases at 500 to 650°F. contain about 2.7 per cent S02.) The ore is roasted to hematite rather than magnetite—the latter condition resulting in a higher cyanide consumption. Roasting Arsenopyrite Ore for Gold

Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations …
What Are Gold Tailings. To be shortly saying, tailings are ground up rock minus the gold. The placer or rocks mined from underground which contains gold is called ore. The gold mining process involves crushing the ore into sand and dust to liberate and recover the gold. What's leftover is called tailings.

As a kind of refractory gold ore resources [3], deposit of carbonaceous gold ore account for more than 20% gold reserves over the world, containing more than …
Method #2: Gold flotation process. Flotation is a widely used beneficiation method for rock gold ore. The flotation process can maximize gold enrichment into sulfide minerals, tailings can be directly discarded, and the beneficiation cost is low. The gold flotation process mainly includes four stages: dosing, agitation, aeration, and …
Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of …

Tetrahedrite or Gray Copper Ore. Part of the list of all Antimony Minerals Group is Cu2Sb8S7. — Color, grayish or grayish black; powder, grayish or grayish black, sometimes inclining to brown or reddish; luster, metallic; H = 3 to 4; G=4.4 to 5.1; no cleavage; composition, about 52% copper, and, in addition to the antimony and sulphur, …
Zinc complexes are more likely to cause trouble in the cyanidation of silver ores because such ores contain much more silver than a gold ore contains gold. Thus, a much larger amount of zinc is required to precipitate the dissolved silver, resulting in cyanide solutions carrying a relatively high percentage of zinc cyanogen complexes and …
