SGS MINERALS SERVICES – T3 SGS 960 11-2009
Beneficiation is the process where ore is reduced in size and gange separated from the ore. Since all iron ore deposits have unique mineralogy, the beneficiation process is specific to each deposit. Separation of certain minerals can be efficiently achieved by taking advantage of the physical, electrical and magnetic properties.

The specific energy was equivalent to 151 MJ/t of ore. This figure was more than twice the average value of electricity consumption at a concentration copper plant in Chile for 2015 (80.8 MJ/t ore) as reported in Ref. [ 71 ]. If the specific energy is expressed by a ton of metal concentrate, this value was 34278 MJ/t.
