Differences in Properties between Pebbles and Raw Ore from a SAG Mill
Semi-autogenous (SAG) mills are widely used grinding equipment, but some ore with critical particle sizes cannot be effectively processed by SAG mills and turned into pebbles. This research aims to analyze and compare the properties of raw ore and pebbles from a zinc- and tin-bearing ore. The results show that the contents of sphalerite, …

Barite Beneficiation Process and Plant Flowsheet
Barite-Fluorspar-Zinc Ore Grinding. The ore for treatment is of such a nature that conventional grinding to —65 mesh using a ball mill classifier circuit results in excessive overgrinding of the barite. To avoid this condition a rod mill is used instead of a ball mill for reducing the feed for flotation.
