Effect of grinding conditions on mechanochemical grafting ,

According to Fig 1 the volume averaged median particle diameter x 50,3 of the quartz particles decreases slower with growing grinding time if the material is ground in an aqueous solution of the monomer VP instead of pure water although the quartz concentration 20 wt is always the same The size of the quartz particles ground for 12 h, however, does not depend remarkably on the VP ....

Zinc processing

The most common method for accomplishing this concentration is to isolate the sulfide mineral from the impure constituents, or gangue, by flotation separation In this process, the ore initially is crushed to about 19 centimetres 075 inch , combined with water, and ground to less than 01 millimetre in a ball mill...
