Leeson Electric Corp. is building a 4,500-sq.-metre motor distribution facility at its headquarters in Grafton, Wisc. It will be attached to Leeson’s current 14,400-square-metre complex.

Larox of Finland has published a pressure filtration application guide for mining and minerals. The guide tells how a talc producer has reduced moisture and increased production throughput by introducing pressure filtratrion. At a zinc processing plant, the problem of high lead dust content in air was solved by lowering the moisture content of zinc and lead concentrates. In addition, a surge in capacity made plant expansion possible. A copper and lead capacity plant was able to meet the transportable moisture limit after the introduction of pressure filtration technology.

Du Pont Co. has decreased the price of sodium cyanide, used primarily in precious metals mining. The decrease applies to all grades and packages and varies from 4 cents to 6 cents per lb. The price decrease reflects current market overcapacity due in large part to rapid production expansion to ease the previous supply shortage, says David Zimmerman, manager of the solid cyanides business. To meet demand, DuPont has expanded its operations in Memphis, Tenn. and Texas City, Tex. and is starting up a 20-million-lb-per-year facility in Mexico.
