A remarkable 90 years of lead smelting at Mount Isa Mines

Construction of Mount Isa's Lead Smelter began in 1929 and was commissioned in June 1931, at a total cost of 3,500,000 pounds, including all site infrastructure. By 1931, Mount Isa's very first tonne of lead bullion was cast and shipped overseas, which marked the start of a remarkable 90 years of lead smelting at Mount Isa Mines.

BACKGROUND REPORT

the bullion in cast iron kettles, occurs in five steps: 1) removal of antimony, tin and arsenic; 2) removal of precious metals by Parke's Process, in which zinc combines with gold and silver to form an insoluble intermetallic at operating temperatures; 3) vacuum removal of …

eTool : Lead: Secondary Lead Smelter

Reverberatory furnace tapping operations involve pouring the molten lead and slag from the furnace into molds or ladles. Some smelters tap metal directly into a holding kettle, which keeps the metal molten for refining. Other smelters cast the furnace metal into blocks and allow the blocks to solidify. Potential Sources of Exposure

Fluxes for melting aluminum

Drossing fluxes promote separation of molten aluminum entrapped in the dross (sometimes up to 80%). Besides chlorides and fluorides drossing fluxes contain oxidizing component (KNO 3) reacting exothermically with aluminum when heated.Heat generated by drossing flux improves wettability and fluidity of the entrapped aluminum, drops of which …

12.11 Secondary Lead Processing

the holding pot, the lead is usually cast into large ingots called pigs or sows. About 18 percent of the charge is recovered as slag, with about 60 percent of this being a sulfurous slag called matte. Roughly 5 percent of the charge is retained for reuse, and the remaining 7 percent of the charge escapes as dust or fume.

What Is Lead Smelting?

This material is drawn from the blast furnace, and it has to go through a drossing process. Professionals put the bullion inside a kettle to cool it down to between 700 and 800 degrees. Drossing produces two different materials: dross and molten lead.
