The hammer mill is made up of a steel drum that houses a shaft of many hammers. This type of mill is often used as a secondary or tertiary crushing method to achieve the desired results, but can also be the primary mill when called for. The hammers are spun at high speed as the material enters the drum.

In processing lines the combination of crusher, HPGR and IsaMill can force out the classical comminution line with crusher, SAG mill, ball mill and vertical stirred mills 4. The fineness requirements depend on the required liberation particle size for the flotation and on the classification process downstream of the comminution process.

Sodium hydrogen sulfide NaHS is commonly used as a copper depressant in the selective flotation of copper and molybdenum ores. However, the process is facing health and safety issues because NaHS readily yields toxic hydrogen sulfide gas H 2 S under acidic conditions. In this study, Na 2 SO 3 was proposed as an alternative copper depressant. The effect of Na 2 SO 3 on the surface ...
