Efficient Technology for Improving Grade of Iron Concentrator and Reducing Impurity

For efficient filtering of concentrate, BPF automatic pressure filter is adopted to filter minerals that are hard to be filtered, filter at a plateau or in cold areas where there is a higher requirement on moisture content, or filter on occasions with higher demand on automation. Filter cake with low moisture can be obtained.

Case Analysis

At a large-scale poly-metal concentrator with a daily processing capacity of 2,000 tons, 4 sets of BPF automatic pressure filters were adopted for filtering flotation copper, lead and zinc concentrate respectively, with moisture content standing at 6~11% and the processing capacity per unit area reaching 300~400kg/m².h.
