Ore Used Impact Ball Mill

Lead and Zinc Energy

The ore is then ground in rod and ball mills The slurry may also be ground in autogenous mills (a mill where the ore acts as the grinding medium) or semi autogenous mills (steel balls are added to the ore) Hydrocyclones are used between each grinding step to separate coarse and fine particles The coarse particles are returned to the mill for further size reduction Milling is carefully
