May 25, 2021 Iron ore mining plant. With the increasing demand for iron ore, the number of open pit iron ore mines and mining rate are increasing, and there are more and more problems faced in the process of iron ore mining, which seriously affect the safe production of mines.A Thickener Plant will dewater the tailings from very low solids density to medium and high density. As an example from 5 % w/w solids up to around 65 to 70 % w/w solids for an iron ore tailings. The Thickened Tailings slurry is then pumped to Filter Plant in which thickened tailings slurry is further dewatered into filter cake. Get a quote
