In flash smelting, dry sulfide ore containing less than 1% moisture is fed to the furnace along with preheated air, oxygen-enriched air (30–40% oxygen), or pure oxygen. Iron and sulfur are oxidized. The heat that results from exothermic reactions is adequate to smelt concentrate, producing a liquid matte (up to 45% nickel) and a fluid slag.

Sulfur dioxide (SO2) is a major air pollutant emitted in the roasting, smelting and converting of sulfide ores (nickel sulfide concentrates contain 6-20% nickel and up to 30% sulfur). Sulfur dioxide releases can be as high as 4 metric tons of sulfur dioxide per metric ton of nickel produced, before controls. Reverberatory furnaces and electric ...

A Balanced Tin Supply. World tin production has been quite stable in recent years, with refined tin production between roughly 330,000 tpy and 370,000 tpy. This is made up from mine production between 270,000 tpy and 310,000 tpy, and the balance by 50,000 – 70,000 tpy of secondary refined tin production. Tin recycling will continue to play a ...

Smelting and other primary-production- related processes (mining, refining and production of anodes for smelting) together are responsible for over 90% of the total emissions [2].

Description. The interviews with both Curtis Dungey and Chuck O'Donahue discuss their association with the Tacoma Smelter and ASARCO. O'Donahue, who worked at the plant for over twenty years (1963-1985), also was active as a union leader for Local 25. Dungey was the senior environmental scientist for ASARCO who oversaw the closure of the plant.
