Frontiers Effect of Grinding Media on Grinding-Flotation

Experimental Methods Grinding Tests. The chalcopyrite and pyrite are crushed with a small hammer to 1–2 mm, then, the samples were ground in a grinding bowl using the 15 mm nano-ceramic balls and 12 mm steel balls (of the same weight) as grinding media. Firstly, the grinding medium and appropriate amount of sample were added in the grinding bowl.
