Effect of flotation reagents on the wet grinding of ...
Generally, wet grinding of ores is performed in mineral processing. After this step, ores are beneficiated typically by using froth flotation method. In the flotation process, specific reagents are used depending on mineral properties in the ore. Some of the reagents can be introduced into pulp during grinding to serve as grinding aid.
