Interactive effect of minerals on complex ore flotation:

2019-10-13  Therefore, magnesite flotation should be studied in economic and environmental perspectives. One of the essential challenges during magnesite flotation in the presence of carbonate gangues is the occurrence of slimes. In general, slime problems are largely caused by the associated carbonates in low hardness.
