Flash smelting has been the most widely adopted copper matte smelting process since 1970. More than 40 furnaces have been installed to replace reverberatory furnaces or at new smelting operations. Nowadays the Outokumpu-type smelters account for more than 50 % of world primary smelter capacity.

Nationalization and Mining: Lessons from Zambia budget deficit increased to US$150 million. Foreign debt of $2.6 billion had to be restructured. By 1986 a noticeable decline in copper production resulted in the closure of many mining units and led to the implementation of a five-year plan to revive the company8. This was not successful, and by

7.1 Process Overview 7.1.1 Surface Mining Surface mining is the primary source of gold and silver. It requires extensive blasting as well as rock, soil, and vegetation removal to reach load deposits. Ore is removed from the mine and transported to milling and beneficiating plants for concentrating the ore, smelting, and/or refining.

Early application of bioleaching to copper mining centred in its recovery from dumps (Gentina and Acevedo, 1985; Acevedo, 2002). This is a low technology process and renders low productivities and recoveries. Nevertheless, dump bioleaching is economical, mainly because it recovers copper
