WebA comparatively smooth band, which is always found on the upper surface immediately within the perimeter, is due to the more rapid cooling of the metal where it touched the cold tray. The central part shows a marked rising, due to the evolution of sulfurous acid, and proves that at that time sulfide ores were being smelted. WebA number of technologies are being used to capture and remove arsenic from smelting stacks and mine tailings. Air pollution can be controlled effectively using scrubbers, electrostatic precipitators, and baghouses in smelters, which are capable of removing up to 99.7% of the dust and fumes produced during roasting and smelting.

WebCopper was initially recovered from sulfide ores by directly smelting the ore in a furnace. [9] The smelters were initially located near the mines to minimize the cost of transport. This avoided the prohibitive costs of transporting the waste minerals and the sulfur and iron present in the copper-containing minerals. The roasting process is generally undertaken in combination with reverberatory furnaces. In the roaster, the copper concentrate is partially oxidised to produce "calcine". Sulfur dioxide is liberated. The stoichiometry of the reaction is: CuFeS2 + 3 O2 → 2 FeO + 2 CuS + 2 SO2 Roasting generally leaves more sulfur in the calcined product (15% in the case … ipv highwaysSmelting is a process of applying heat to an ore, to extract a base metal.
