TSL and blast furnace operations. The top submerged lance (TSL) and blast furnace operations are the actual smelting part of the process and involve the high temperature reduction of sinter with metallurgical coke to produce a crude lead bullion and slag. Lead bullion contains small amounts of other metals including silver doré, gold and copper.
Oct 09, 2019· A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the ...
The fuming slag from the secondary furnace contains lead <0.5%, zinc <1% and silver<10ppm. The fuming slag is safe for landfill. Both furnaces apply oxygen-enriched air and use crushed coal as fuel and reduction agent. This solution allows lead/silver separation from zinc to avoid silver loss and lead being locked in the circle, of high ROI.
