lead smelting can also be achieved with high lead concentrate feeds. The Isasmelt process has been used instead of a sinter plant at the YMG Qujing operation, Kunming China. The high lead sulphide concentrate feed is used to smelt direct lead and produce leadrich slag. The Shui Kou Shan lead smelting process (SKS) is a bath smelting

Extraction Indirect smelting. Before lead concentrate can be charged into traditional blast furnaces for smelting, In the Isasmelt process, a gas or air lance is brought in through the top of a furnace and its tip submerged in the sulfide concentrate. A blast from the lance produces a turbulent bath in which the concentrates are oxidized to

Jul 01, 1992· The lead Isasmelt process is a continuous twostage process for the production of crude lead from concentrate. It is based on the use of a top entry, submerged Sirosmelt lance to produce turbulent baths in which high intensity smelting or reduction reactions can occur. Krebs was the designer of the solvent extraction section. In a new

Sometimes, however, it is necessary to remove leads. This is called lead extraction. The surgeon opens the area where the leads are attached to the pulse generator and disconnects the leads. Laser or mechanical sheaths are then placed over the leads to free them from the body. This allows the leads to be removed safely from the body.

The ISASMELT process is an energyefficient smelting process that was jointly developed from the 1970s to the 1990s by Mount Isa Mines (a subsidiary of MIM Hings and now part of Glencore) and the Government of Australias CSIRO. It has relatively low capital and operating costs for a smelting process.
ISASMELT technology has been applied to lead, copper, and nickel smelting.
