1 crushing and grinding of the ore 2 concentration or benefaction of the ore 3 extraction of crude metal from concentrated ore 4 purification or refining of the metal 1 crushing and grinding of the ore the ores occur in nature as huge lumps they are broken to small pieces with the help of crushers or grinders.

investigations have been carried out to evolve a grinding aid useful in grinding a 40 ironbearing magnetite containing quartz as the major gangue based on studies conducted with pure magnetite pure quartz and its synthetic mixturethese investigations established that an addition of 200 g of cao per metric ton of ore was the most effective in grinding quartz preferentially over magnetite.

the ores generally occur in nature in the form of huge lumps these lumps are broken into small pieces with the help of grinders or crushers so that the chemical changes which have to take place later on may become convenient this process is called crushing which is done by jaw crushers.

Autogenous grinding the process of grinding ore in a rotating cylinder using large pieces of the ore instead of conventional steel balls or rods b back the ceiling or roof of an underground opening backfill waste material used to fill the void created by mining an orebody.
