CuCr composite particles have been obtained using copper deposition from the solution of its sulfate onto chromium powder particles with the simultaneous mechanical activation (MA) of the mixture in an AGO-2 planetary ball mill for 5 min. The CuSO 4 ·5H 2 O concentration in the solution with complete copper reduction provides a molar ratio of Cu/Cr = 1.

Chromium, with and without 4 volume percent thoria, and nickel powders were ground to fine powder sizes by ball-milling in gaseous hydrogen halides. After reducing the milled chromium in flowing hydrogen under pulsating pressure at about 680 deg C submicron-size powders with 4 to 500 ppm residual halogens were obtained.

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
