Production of High Grade Iron Ore Concentrates Using Flota

forced iron ore producers to re -examine their process flowsheets and evaluate alternate or supplemental processing routes. The requirement for higher quality pellets demands that the silica content be lowered to levels ranging from 2.0% SiO 2 to below 1.0% 2

Production of High Grade Iron Ore Concentrates Using Flota

CPT Inc. has developed a flotation process for the production of Direct Reduction (DR) as well as Blast Furnace (BF) grade concentrates utilising column flotation technology. This process has been adopted by several major iron ore producers and current aggregate production is approximately 50 MTPY of DR grade concentrates.

The processing of iron ore requires physical processes that help ensure conformation to sizing specifiions and where required help the ore achieve grade targets. The sizing separation of iron ore is achieved through the comminution and screening processes

Iron processing - Ores | Britannica

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
