 — Most supply was coming from the Chinese stibnite mines (mainly the Xikuangshan mine), stibnite is the most common antimony ore mineral, ... (e.g. Anzob produces a Hg-Sb concentrate) and one mine produces antimony as by-product of lead …

 — Fortunately for the U.S. at that time, a gold mine in central Idaho called the Stibnite mine was able to step up production of the antimony that is an element in the mine's ore and helped fill ...

Estimates of the abundance of antimony in the Earth's crust range from 0.2 to 0.5 parts per million. Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) …

 — In concentrating pure stibnite ores it is not necessary either to make allowance for extraction of other values or to design the process for separation of contaminating sulphide minerals. In cases where the surrounding rock and ore matrix are minerals such as quartz or feldspar, conditions should favour gravity separation because …

 — Antimonite ore is processed by hand-picking–flotation or heavy medium separation–flotation to pick out lump ore, rich lump ore, and concentrate that will go into the smelting process. Antimony smelting is done through the pyrometallurgical process or …

 — The article presents results of hydrometallurgical and bio-treatment of antimony ores and recommend new dissolvents for antimony sulfides. The authors introduce a processing plant which is a single operating processor of antimonic gold-bearing alloys with the successful electrolytic refining of anodes and production of cathode …

China's antimony mine production has fallen significantly over the past several years. However, China continued to be the leading global antimony producer in 202 3 and accounted for 48% of global antimony mine production. The world's leading antimony-producing mine was a gold-antimony mine with 23,000-ton-per-year capacity in Russia.

 — Antimony has a negative effect on the gold extraction from antimony–gold concentrate, and it is necessary to remove antimony in advance. For a high calcium low antimony–gold concentrate (Ca–Sb–Au ore), this study proposed to pre-remove antimony using slurry electrolysis in HCl–CaCl 2 system. The results indicated that the optimal …

 — The tin mine in Hunan province is the biggest antimony ore producing area worldwide. ... Membrane separation is a technology of separating or concentrating solvent and solute under the action of external pressure by using the difference of selective permeability of the membrane to different components in the mixture. According to the …

 — 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 antimony sulfide …

 — Aside from antimony ore grade, this decision falls on the mineral's association with other metals, for e.g. lead, copper, iron, mercury, arsenic, silver and gold, as well as other parameters such as ore matrix and type (sulfide or oxide). ... depending on the …
