Tonghua Iron and Steel Group slab mining company concentrator is a large beneficiation plant, after years of renovation and expansion, has now formed five grinding series, with an annual output of 1 million tons of iron concentrate, grinding process mainly for stage grinding, stage selection Do not, vibrating screen from the cycle and magnetic separation column re-election process.
