recovery of pyrite decreases gradually from 83.79% at pH 6.87 to 64.41% at pH 11.68. The decline in pyrite microflotation recovery under strong alkaline conditions is due to the formation of a hydrophilic ferric hydroxide film on the pyrite surface, which inhibits the flotation of pyrite [8]. The recovery of talc with or without the presence of the
