A filtering system at a South Australian zinc mine has helped bring a site into full production six months earlier than anticipated, exceeding all production start-up expectations. The filters boosted filtration capacity by 30% and increased production by allowing the mine to handle higher lead concentrates when the ore grade is high.

In the first of a series of articles, Ken Sutherland looks at one of the minor end-use sectors, which, although important industries in their own right, actually have relatively small shares of the filtration and other separation equipment market. In the present case, the review is of the production of minerals, other than fuel materials, and the making of metals, both ferrous and non-ferrous.
