Southern African Pyrometallurgy 2006 Johannesburg, South Africa, March 58, 2006. The `Southern African Pyrometallurgy 2006´ international conference was set up to showcase southern African pyrometallurgical operations, and to provide a forum for the exchange of ideas between people working at various types of smelters.
Extractive metallurgy is that branch of metallurgy that deals with ores as raw material and metals as finished products. It is an ancient art that has been transformed into a modern science as a result of developments in chemistry and chemical engineering.
About the author (2002) Professor Davenport is a Fellow (and life member) of the Canadian Institute of Mining, Metallurgy and Petroleum and a twentyfive year member of the () Society of Mining, Metallurgy and Exploration. He is recipient of the CIM Alcan Award, the TMS Extractive Metallurgy Lecture Award, the AusIMM Sir George Fisher Award,...
Pyrometallurgy of copper Responsibility: international symposium organized by the Metallurgical Society of Canadian Institute of Mining, Metallurgy and Petroleum, Chilean Institute of Mining Engineers, and Minerals, Metals, and Materials Society of the AIME.
The Inca bronze alloys were also of this type. Arsenic is often an impurity in copper ores, so the discovery could have been made by accident. Eventually arsenicbearing minerals were intentionally added during smelting. [citation needed] Copper–tin bronzes, harder and more durable, were developed around 3200 BC, also in Asia Minor.

This new edition has been extensively revised and updated since the 3rd edition published in 1994. It contains an even greater depth of industrial information, focussing on how copper metal is extracted from ore and scrap, and how this extraction could be made more efficient. Modern high intensity smelting processes are presented in detail, specifically flash, Contop, Isasmelt, Noranda ...

Pyrometallurgy of copper in the past and at present lowgrade material because it is more economical. In the copper industry highgrade massive sulfide ores were broken down into small lumps and charged to a vertical furnace whereby the unwanted rock was removed as a slag and the coppercontaining minerals were collected as a matte.
electrometallurgy. Pyrometallurgy is the most ancient technology, while hydro and electrometallurgy are more recent. No wonder then that, in some cases, these new technologies are displacing the older ones gradually, ei ther because of improved efficiency and better econom ics or to comply with environmental regulations [13].

After injecting biodiesel into molten copper slag at 1523 K for 4 minutes, magnetite was reduced from % to less than % and the viscosity decreased from poise to poise. This low viscosity is beneficial for separation and recovery of copper from the molten slag.
