Crude lead produced during smelting operations is remelted in cast iron kettles and refined by the addition of reagents, such as sulfur and caustic soda. The purified lead is then cast into molds or ingots. Significant lead emissions can occur from poorly controlled refining, casting, and drossing operations. Refining; Casting; Drossing

drossing kettles. On the basis of these findings, sodium treatment was incorporated as a standard part of Glover's rough drossing operation. The only significant capital expenditure required was for facilities to handle tank car quantities of sodium. Over …
Effect of Smelter's Practice on Dross Quality • Following key steps are involved • Drossing Temperature. • Fluxing Practice before drossing. • Skimming Practice. • Cooling of dross as soon as possible. • WAYS TO COOL THE DROSS. • Air Cooling. • Rotary Dross Cooler. • AROS Argon Cooler. • Dross Press (Most Widely used Practice)
The smelting process is a major source of lead fume emissions. Smelting involves the reduction of lead-bearing scrap into metallic lead in a furnace.
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 …

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.
–Tailor made: Based on experience and inputs from Cast House application (Foseco makes > 200 MT of compacted flux in a month) –Improved Drossing and reduced loss –Reduced corrosion of structure (Reduced aggressive fumes) –Potential to prolong the need for big cleaning (Reduced oxide build up since dross is dry)
