Increasing Non-Concentrate Feed to Brunswick Smelter's Updraft Sinter Machine

摘要

In 2000, Xstrata Zinc - Brunswick Smelter began to feel the impact of a changing feed market in the leadrnsmelting industry. Global demand for lead concentrate was increasing due in part to China's growingrnconsumption of externally produced concentrates. As a result of the tightening concentrate market, thernSmelter adopted a strategy in 2003 to increase its proportion of non-concentrate feed.rnThis paper will describe the technical challenges and developments undertaken to increase the proportionrnof non-concentrate feed to Brunswick's updraft sinter machine. This development has allowed the Smelterrnto remain competitive with a diverse feed base.
