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 ...
