In the primary stage, the devices used are mostly jaw crushers with openings as wide as two metres. These crush the ore to less than 150 millimetres, which is a suitable size to serve as feed for the secondary crushing stage. In this stage, the ore is crushed in cone crushers to less than 10 to 15 millimetres.

heat generated in the crusher. At most operations, water is sprayed into a crusher and onto conveyor belts to suppress dust in the plant, but this usage represents only a small fraction of the plant's total water usage. The crushed ore is transferred to a semiautogenous (SAG) mill or ball mill where the ore is further reduced in size.

Generally, the process can be roughly divided into three main stages: the smelting (reduction) of the ores to produce a bloom (a spongy mass that is a mixture of metal and slag), the refining of the bloom (primary smithing) to produce a more compacted metal (a bar ingot) and the forging of the end product (secondary smithing, see Fig 1 ).
