For low-grade iron ore dressing, the SS in process waters are highly dispersed during separation processes and difficult to completely remove—and this issue becomes serious with SS accumulation through process water reuse (Wang et al., 2019; Yenial and Bulut, 2017). SS removal from this process water form therefore needs more insight into the ...

As for ore properties, oolitic hematite ores in Europe have uniform mineral distribution and little difference in ore structure, which bring a lot of difficulties for their utilization. While in China, oolitic hematite ores have relatively higher grade and larger differences in ore struc-ture. These make it hopeful for the exploiting of such ores.

Zhang et al. [23] studied the process mineralogy of copper ores and found that copper minerals are mainly sulfide minerals that are easily floated, but most of them are embedded at around 0.3 mm, requiring a grinding fineness of 85–90 % −300 mesh to make the copper ore fully dissociated.

The ore is generally associated with rock impurities like clay, sand etc. called 'gangue or matrix'. The purification of ore means removal of gangue from the powdered ore. This process is otherwise called concentration of the ore or ore dressing. Thus, the percentage of the ore in the concentrated ore is higher than that in the original ore.
