Processes Kivcet Flash Smelter MetSoc of CIM

A mixture of lead-zinc-iron oxides and flux agents form a semi-fused slag which collects under a layer of coarse coke called a coke checker in the first compartment of the furnace, called the smelting shaft. As this coke sinks through the slag, the lead oxide is reduced to lead bullion.

Smelting chemeurope.com

Chemical reduction, or smelting, is a form of extractive metallurgy.The main use of smelting is to produce a metal from its ore. This includes iron extraction (for the production of steel) from iron ore, and copper extraction and other base metals from their ores. It makes use of a chemical reducing agent, commonly a fuel that is a source of carbon such as coke, or in earlier times charcoal

The Direct Iron Ore Smelting Reduction Process (DIOS) directly uses noncaking coal in a powder or granular form, and iron ore without the use of coke or a sintering process, which are normally required in blast furnace processes. The noncaking coal is directly fed to a smelting reduction furnace, while the iron

In the furnace the iron ore is increasingly reduced and liquid iron and slag are collected in the bottom of the furnace, from where they are tapped. The slag from the blast furnace is granulated, pelletised, or tapped into slag pits. The slag granules or pellets are usually sold to cement manufacturing companies.
