May 31, 2016 · The rods are free inside the mill. When the mill is turned, the rods tumble against one another grinding all the ore that is between them to aid in the grinding, water is added with the ore as it enters the mill. So from that you can see why it is called a wet tumbling mill. The ore is ground wet and the mill revolves

flotation reagents - metallurgist & mineral processing

To clean the mineral surfaces, thus enhancing the action of other reagents. To depress certain minerals. Soluble salts may have their source in the ore or water, or both, and in precipitating them out of solution they generally become inert to the action of flotation reagents. Soluble salts have a tendency to combine with promoters thus withdrawing a certain proportion of the reagents from action on the mineral to be …
