Extracting antimony from high arsenic and gold

2019-6-1  This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about 5.50% and 1.14%, respectively.

Antimony & Gold Tri Star

Refractory gold is in the ground gold ore trapped in sulphide lattice structures that conventional processes are unable to unlock. The clean roasting antimony technology developed by Tri-Star sold to joint venture company, Strategic & Precious Metals Processing LLC in 2015 has opened the treatment again of these world gold resources, estimated

Natural antimony consists of a mixture of two stable isotopes that have atomic weights 121 (57.25 percent by weight) and 123 (42.75 percent by weight); in addition, about three dozen radioactive isotopes are known. Antimony’s average concentration in the Earth’s crust is 0.20 gram per metric ton (g/t). Antimony metal melts at 630.6 o SS

2019-4-22  This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE). The results indicated that the leaching efficiency of antimony was higher than 98%, and those of iron and arsenic were about 5.50% and 1.14%, respectively.

Invisible gold in ore and mineral concentrates from

About 50–55% of the gold produced at Hillgrove occurs invisibly in arsenopyrite and pyrite. Gold losses of ∼20% into tailings are due to this mineral chemical factor. From PIXE probe analyses, it has been found that arsenopyrite contains 255–1500 ppm Au and pyrite 24–223 ppm Au, with Au contents of each mineral correlating moderately with As content.

Photos of gold ores, quartz, telluride gold ore and

2014-6-22  In most gold ore, the gold is present in tiny specs, either within minerals like pyrite, or spread out free among the quartz. Only a very small percentage of the gold occurs in visible pieces like this. of gold ores comprises the gold-telluride group. The gold telluride ores occur with silver, or with silver, lead and antimony, or as

Establishing thE ProcEss MinEralogy of gold orEs

Antimony, bismuth sulfide and telluride gold ores: Antimony, bismuth sulfide and telluride gold ores are often somewhat refractory due to the presence of slow-dissolving gold minerals such as aurostibite, maldonite and gold tellurides. Carbonaceous ores: The gold is

Antimony Ore Article about Antimony Ore by The

Antimony Ore. any of the natural mineral formations containing antimony in compounds and concentrations that make commercial use technically and economically feasible. Of the antimony ores proper, the major mineral is antimonite (Sb2 S 3 ), which contains up to 71.4 percent Sb; in rare cases, antimony ores are represented by complex sulfides of

The Source of Gold Its Ores and Minerals

Gold also occurs as tellurides such as calaverite. Common gangue minerals in gold ores include quartz, fluorite, calcite and pyrite, but many others can be found in smaller amounts. Gold Ore Minerals: The most prominent is native gold most of the native gold contains a small amount of silver, copper, platinum, etc. Telluride minerals are the

Basic theory and optimization of gold containing

2019-1-21  Gold containing antimony ore is a type of refractory gold in which gold is intimately associated with stibnite (Guo et al., 2017). When the traditional cyanidation method is used for gold extraction, thioantimonate by stibnite decomposition reacts with oxygen to form antimony acid salt, or antimony

Antimony Mobilization through Two Contrasting

2009-4-22  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 were low (<100 mg/kg) compared to arsenic (As

Invisible gold in ore and mineral concentrates from

Vein-hosted mesothermal stibnite-gold mineralisation at the Hillgrove Au-Sb mine in northeastern New South Wales has a halo of veinlet and disseminated auriferous arsenopyrite and arsenian pyrite in metasedimentary and granitic host rocks. About 50–55% of the gold produced at Hillgrove occurs invisibly in arsenopyrite and pyrite. Gold losses of ∼20% into tailings are due to this mineral

A selective process for extracting antimony from

2017-5-1  The leaching experiments demonstrated that antimony could be selectively leached from refractory gold ore. Under optimal conditions, the leaching recoveries of antimony, gold, and arsenic were 96.64%, 1.44%, and 0.41%, respectively. (2) Antimony in the leaching solution could be precipitated in the form of sodium pyroantimonate by pressure
