Pyrometallurgical Refining is performed in liquid phase, which means that the crude Lead must be melted to temperatures from 327ºC (Lead fusion point) to 650ºC. As a general trend, the process is performed in batches of 20 to 100 tons, according to the refining plant capacity.

The aim of lead refining is to produce sellable lead metal. This is done in a refining kettle by separating out unwanted accompanying elements and alloying. After copper has been separated out, arsenic, tin and antimony are removed from the lead melt. The resulting dross is recycled. Kettle for lead refining.

Plants for the production of lead are generally referred to as lead smelters. Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal. Reduction is
