Optical Sizing Analysis of Blasted Rock: Lessons Learned
Optical sizing of blasted rock has been used for about 15 years. Originally thought of as a specification type of measurement tool, it has over the years evolved into a process control tool. Because of the difficulty defining what the size of an irregular fragment is, it is difficult to reconcile different methods of measurement. Screening nominally measures …

Copper Ore
Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.
