iron processing - iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...
Feb 29, 2016· Roughing can be considered as the upgrading of the ore to produce either a low grade, preliminary concentrate or to reject tails that contain gangue at an early stage. The equipment used in this part can produce a large amount of concentrate and permit the recovery of a very high percentage of gold, produce clean tails or a combination of both.
