The weld joint in the steel backing is then made with the 65% nickel-copper followed by the steel filler runs. If the preparation is made from the cladding side, the joint is partially filled with steel weld metal and then completed with the combination of the 65% nickel-copper filler and then 70-30 Cu-Ni filler.

Then wet grinding in semi-autogenous rod or autogenous ball mills takes place. Size classification takes is performed in cyclones. In the next step of beneficiation, valuable minerals and gangue are separated by froth flotation of the ore pulp, which exploits the different surface properties of the sulfidic copper ore and the gangue [46].

A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.

grinding wheels. A typical sequence might begin with 120- or 180-grit papers and pro- ceed to 240, 320, 400, and 600 grits. Scratches and damage to the specimen sur- face from each grit must be. removed by the next finer grinding step. The surface damage remaining, on the specimen after grinding must be removed by polishing.
