The High Mud Content of The Raw Ore Affects The

2021-2-15 · When studying how to reduce the influence of slime on the flotation effect of gold ore, we must first understand the property of the ore with high mud content. This type of gold ore contains a large number of gangues of easy flotation and easy argillization (talc, serpentine, chlorite, calcite, dolomite, sericite, kaolinite, montmorillonite, feldspar, etc.).
