Extraction of Antimony

For volatilisation roasting either the Herrenschmidt or the Chatillon process is used. In the Herrenschmidt process, the furnace is a rectangular shaft of firebrick with firebars arranged in steps. The gases from this furnace are cooled by passing them through a series of iron pipes into a wooden tower packed with coke down which water trickles.Details
