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 ) is the predominant ore mineral of antimony.
How much Antimony is produced and released to the environment? In 1984, 64.5 million lbs. antimony ore was mined and refined. Production of the most commonly used antimony compound, the trioxide, increased during the 1980s to about 31 million lbs, reported in 1985.
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. So the processing method of Xinhai is gravity separation-flotation process.
The invention discloses a method for preparing sodium antimonate from an antimony oxide ore via an alkaline approach. The method comprises the following steps: (1) leaching the antimony oxide ore, (2) purifying filtrate, and (3) oxidizing the purified filtrate.
The industrial methods for refining antimony are roasting and reduction with carbon or direct reduction of stibnite with iron. The largest applications for metallic antimony is an alloy with lead and tin and the lead antimony plates in lead–acid batteries .
Plans, however, were underway to install a system for complete recycle of the antimony in the effluent from the electroly- tic production of antimony back to the antimony plant in- fluent (ore leach).

For roasting sulphide ores two methods are used, viz., simple roasting yielding mainly antimony tetroxide, and volatilisation roasting yielding mainly antimony trioxide. In the former, reverberatory furnaces are employed, the flue gases passing through a condensing plant for the recovery of any antimony trioxide that may be formed.
Dear Riina, I want to analyze antimony in ore (the ore is rich in lead, silver, antimony and arsenic). Can you tell me the dissolution method for antimony? So that I could analyze antimony in ICP-OES.
method to ore ground to approximately 80-mesh, 96.0 percent of the mercury in the ore was recovered in a cinnabar concentrate that assayed 80.3 percent Hg and 1.3 percent Sb. The antimony product contained 80.7 percent of the antimony; it assayed 0.82 percent Hg and 62.3 percent Sb. The mercury product contained 11.6 percent of
Gold ore,silver ore,iron ore,lead ore,zine ore,antimony ore . Retorting is the process of distilling off the mercury from the metal/mercury amalgam and is . In this way, the retort is safe for human use and the mercury has a high recycle rate.

antimony prices Pricing of the metal is generally based on the London Metal Exchange average price C.I.F. Rotterdam per metric ton (a metric ton contains 2,204.6 pounds). Antimony oxide contains 83.1% antimony metal and it is typically the preferred product for selling.
Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide.Little antimony is currently mined in the United States.
