- W4256221474 abstract "The use of tonnage oxygen in non-ferrous extraction metallurgy is now established practice and part of conventional technology, however it was not always so. While technically understood in the scientific literature decades before major developments were commercialized, widespread application, historically, is comparatively recent. In this paper, the progress of oxygen applications is traced and factors governing the rate of commercialization and acceptance within the industry are examined. Canada has in fact played a leading role in developing oxygen-driven processes in non-ferrous metallurgy. As examples, Cominco, at Trail B.C., was the first to use oxygen-enrichment in zinc and lead pyrometallurgy in the nineteen thirties and forties; Inco pioneered oxygen smelting twenty-five years ago when its new flash furnace was commissioned in Sudbury with oxygen produced in the world's third largest plant. Testwork at Noranda's Horne smelter in the sixties and seventies confirmed production improvements with oxygen enrichment in the Noranda Process which now operates with over 400 tonnes of oxygen per day. The first commercial zinc oxygen-pressure leaching process was commissioned at Cominco's Trail plant in 1981 following initial laboratory work carried out nearly 30 years ago by Sherritt Gordon Mines Limited and subsequent joint piloting by Sherritt and Cominco. An appreciation of these and many other developments is also useful in putting into perspective the state of innovation at the present time. Concepts which may lead to new future developments are also introduced." @default.
