Crushing Process Of Sulphide Ore

Sep 01, 2019 Abstract. The effects of crushing energy, ore hardness and particle size of cassiterite polymetallic sulphide ore and lead−zinc polymetallic sulphide ore on the crushing characteristics during impact crushing were investigated by mineral liberation analyzer (MLA) and drop weight test. The results show that both ores contain pyrrhotite
