The modem copper industry presents an excellent opportunity for the application of clean, environmentally friendly techniques using currently available hydrometallurgical technologies. This paper briefly reviews key events in the development of modern hydrometallurgy in Chile. Discussion is given to those prominent events whose impact continues to be felt on most projects currently underway. Mention is also made of the foundations of heap leaching technologies, preceded by agglomeration and acid curing, known as the T.L. Leaching Process, the cornerstone of more recent developments. A review is also presented of the leading copper hydrometallurgy projects of the 1990s. A list of those projects, their tonnages and the estimated date of implementation is provided. The conclusion provides an overview of developments in research and the trends in the implementation of copper hydrometallurgy projects in Chile for the coming years.
