antimony ore compositions . Antimony: The mineral native Antimony information and pictures. Antimony is a native element that can occur in a natural state, but it is rarely pure. It almost always contains some arsenic, and may also contain traces of silver, iron, and sulfur.
Three studies concerning the geochemistry of the semimetal elements: arsenic, antimony, and bismuth, were done to better understand oreforming processes. The scope of these studies varied from regional distributions of the elements to small scale changes in mineral compositions. Regional distribution of the semimetal elements, measured by presence as discrete mineral phases, in the ...
