Falling prices for iron ore with lower quality than 60 % Fe have led increasingly to the design of iron ore beneficiation lines. General problems of water scarcity and risks with tailings dams have led to the focus shifting to dry beneficiation technologies. In the following article, current developments are examined and case studies referenced.
The ore samples were supplied from a new low-grade chromium ore deposit located in Eastern Anatolia in Turkey, and they were characterized in detail in terms of their physical, chemical, and mineralogical properties. The grindability of the ore was determined using the standard Bond Work Index method with a test sieve having a size of 106 µm.
South African chromite mines generally recover 10–15% lumpy/coarse ore (15 ≤ typical size range ≤ 150 mm) and 8–12% chip/pebble ore (6 ≤ typical size range ≤ 15 mm), with the <6 mm fraction accounting for the remainder of ore . The beneficiation of lumpy, chips/pebble chromite is achieved by crushing, screening, and dense media ...
