New Flotation Technology Research on Carbonate-Containing Hematite

Abstract:

A new flotation technology of carbonate-containing hematite was introduced in this paper, The results show that iron minerals are mainly composed of hematite, siderite, magnetite, limonite, ankerite, quartz, hornblende, and a small amount of chlorite, etc. The increase of iron carbonate can deteriorate the normal flotation of hematite, but now a new flotation technology can weaken the negative influence of iron carbonate on flotation, by which we can obtain the iron concentrate with grade of Fe 66.26 %, recovery of Fe 70.23%. It has been comprehensively demonstrated that the dispersant plays an important role in the selective separation of hematite from iron carbonate and iron silicate.
