Converting an idea into a worldwide business commercializing smelting technology

Pyrometallurgy is an ancient art which has defined significant stages of human development. Today, new opportunities for improvements in the economic, environmental, and workplace costs of metal production continue to provide challenges for the profession and industry. Top-submerged lancing technology for the high-temperature processing of a range of metals and wastes is an example that has been taken up by many companies around the world. The furnace system now marketed under the names of Ausmelt and Isasmelt was, in the early stage of its 33 years of development, known as Sirosmelt. The voyage from the original idea through theoretical, laboratory, pilot plant, and commercial developments to establishment of a worldwide business has been both stimulating and rewarding.
