how is antimony processed

 · Production Process Antimony; Antimony Wikipedia. Production process. The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lowergrade ores are concentrated by froth flotation, while highergrade ores are heated to 500–600 °C, the temperature at which stibnite melts and separates from the gangue minerals. .

ANTIMONY is spontaneously flammable in fluorine, chlorine, and bromine. With iodine, the reaction produces heat, which can cause flame or even an explosion if the quantities are great enough [Mellor 9:379 194647]. Even at 10° C. bromine trifluoride reacts with antimony incandescently. Bromine trifluoride reacts similarly with arsenic, boron, bromine, iodine, phosphorus, and sulfur [Mellor 2 ...

 · When used as an alloying element, antimony greatly increases the hardness and mechanical strength of lead. The main use of antimony is to harden lead in storage batteries, and it is increasingly being used in the semiconductor industry. Historically and economically, antimony is the second most important metallic commodity in Victoria, after gold.

 · Today, there is not an active antimony mine in America. The Stibnite Gold Project would be the only domestic source of mined antimony and the Project can help us take back control over one key part of our mineral future. As we continue to move through the permitting process, we are excited about our ability to bring production of this mineral back home to the

Antimony, like many of the metalloids, is relatively toxic. Toxic effects are similar to those of arsenic, causing severe vomiting and eventually death. In trace amounts, the body can process antimony rather well, and in small doses, effects are minor – dizziness, vertigo, and headaches. Because of its use in many disposable products, antimony seepage into water sources is a concern in many ...
