EPA promulgated the Ore Mining and Dressing Effluent Guidelines and Standards (40 CFR Part 440) in 1975, and amended the regulation in 1978, 1979, 1982 and 1988. The regulation covers wastewater discharges from ore mines and processing operations. The Ore Mining Effluent Guidelines and Standards are incorporated into NPDES permits.
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 (Sb2S3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.

Such unpredictability of ore requires expensive exploration to delineate significant deposits. Little to no exploration was ever done of the deposits during active mining. Mining of antimony ore has been limited to northern Sevier County, although some stibnite is also present in Pike County, associated with cinnabar (HgS). Mined ore deposits ...
Nov 14, 2018· Nevertheless, the most significant producers – Russia, Australia and Tajikistan – send their ore straight to China. Polyus' Olimpiada mine in Russia, for example, which produces antimony as a by-product, supplies around 20,000 tons of the ore to China, according to Backeberg.

Jan 11, 2019· Antimony is a lustrous tin-white metal. Although it is usually described as a metal, it possesses mixed metallic and nonmetallic characteristics, and is more properly described as a semimetal or metalloid. The antimony ore found in our mine is Stibnite, which is a sulfide bearing ore and is concentrated using a froth flotation process.
tungsten and antimony ore. Ore mined at the Meadow Creek mine contained 0.23 ounce of gold per ton and 1.6 percent of antimony. That mined at the Yellow Pine mine contained less gold but about 4 percent of antimony and 2 percent of WO8. The tungsten ore body at the Yellow Pine mine was exhausted in 1945. A total
The mine is thought to have been discovered in 1521 and was originally mined for its tin deposits. 464,000 tonnes of antimony were produced at the mine between 1892 and 1929. From 1949 to 1981, 172,000 tonnes of antimony were produced. In 1981 1,700 tonnes of ore was being mined each day which was between 2 and 3 percent pure antimony.
The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore.The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of quartz but contains, in addition, a small amount of talc.

Proportion of antimony ore is far greater than proportion of gangue, so it will be separated by using the method gravity separation. This method has many features, high efficiency, energy saving, and environment protection, which can make the low-grade ore enrichment advance. After gravity separation, the antimony will be purified by floatation.
