Processing Nickel Ores - Mine Engineer

The ore is crushed to -5 inches in primary cone crushers, then reduced to -1/2" in short head cone crushers. The ore is then ground to -100 mesh in ball mills. Using wet magnetic separators the magnetic ore is separated (pyrrhotite) and further reduced to -200 mesh in a ball mill.

Sample Preparation and Physical Testing | SGS

SGS laboratory staff most commonly use a jaw crusher as the primary crushing tool. These crushers can accommodate chunks up to 15 cm and can reduce them in size until 80% of the sample passes through a 2 mm screen. Staff then use ring and puck mills to prepare a smaller particle size if required for sample pulverizing.

As the size of the fines is generally constrained (10 mesh (1.17 mm), 20 mesh (0.85 mm), and 32 mesh (0.50 mm) are most common), testing at crush sizes finer than 6 mesh is not usually practical. However, if the grain sizes of the ore are considered large enough, testing at crush sizes coarser than 1/2" is
