Abstract
A process for removing impurities from copper concentrate prior to smelting is presented here. The concentrate is subjected to thermal decomposition i n a vacuum chamber at temperatures of about 950 degrees C. This pretreatmen t allows the complete removal of arsenic, antimony, bismuth, lead, zinc, as well as of other impurities from the copper concentrate. (C) 1999 Publishe d by Elsevier Science Ltd.
