separation of lead from stibnite ore by floatation

How Antimony is Processed by Flotation - 911 Metallurgist

Mar 19, 2017 ... The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore. The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides.
