Cam milling is a special milling operation that is used to make cams. It involves using a universal diving head to rotate and index the workpiece while the cutting tool removes material to produce the desired shape. You can vary the cam axis between 0 and 90 degrees to obtain an appropriate cam profile.Web

The MF2 configuration is comprised of two rougher flotation stages and a regrind mill between the rougher banks. This stage-wise collection of concentrate targets the relatively coarse BMS and fine platinum sulphide minerals in separate circuits. Thus, the over-grinding of both the valuable minerals and chromite/gangue is minimised .Web

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.Web
