Confined bed comminution in highpressure grinding rollers (HPGRs) and vertical roller mills (VRMs) was previously used preferably for grinding comparably homogeneous materials such as coal or clinker. Meanwhile, it started to complement or even replace tumbling mills in ore beneficiation with ore and gangue particles of rather different breakage behaviors. The selectivity in the comminution ...
The influence of microwave pretreatment on grindability of leadzinc ore was studied through comparison analysis on the changes of particle size distribution, percentage of below mm, energy consumption, and other indexes of grinding products before and after microwave pretreatment in the ball milling process. The results showed that the grindability of leadzinc ore was improved ...
In the 1950s and 1960s ball mills dominated primary grinding, however they were supplanted in the 1970s by AG and SAG mill which also replaced two stages of crushing. Nowadays ball mills still dominate secondary grinding applications, but are increasingly in competition with closed circuit AG/SAG mill circuits and stirred mills .

The leadzinc ore is a typical lowgrade complex polymetallic sulphide ore. Its typical mineralogy is characterized by a high content of cryptocrystalline graphite, low content of lead, zinc, and copper, and fine grain size. However, the aggregation size of sulfide mineral aggregations is coarse, and the symbiotic relationship is relatively simple. Conventional process treatment requires the ...
Little thought had been given to the effect of grinding media on flotation selectivity of copper lead zinc ore. Ore Sample. The mill feed for the pilotplant investigation was from a copperzinc producing mine in northwestern Quebec. A 200 ton sample was made available, free of charge, thanks to the cooperation of a Canadian mining company.
