    Abstract:

    Environmental impact of extraction of natural resources is today in the focus and mining and metallurgical activities to produce metals are not the exception.Copper content in ores today is around 1% and that implies necessarily to eliminate, in some way, around 99% of non useful material. A lot of attention has been pay on metal losses, then trying to recover the maximum of copper from some wastes produced. However, not a lot of attention has been done on those wastes containing other materials, but with some practical use today in various others activities in our society.This presentation will propose some alternatives of use for some wastes coming out from the copper extractive industry, particularly those representing a big amount after extraction processes (gases, tailings, overburden, slags), with special attention to sub products generated during smelting steps (slags).The results of some researches developed over copper slags at the University of Concepcion, where a plant design to recover some valuable metals has been established, make possible to find economical alternatives for these kind of wastes, and, by this way, diminish strongly the environmental impact of the copper mining industry.Results obtained specifically for slags, showing recovery of various metals as well as the utilization of other contained materials will be shown. As promissory results, it is expected to extend this kind of research to others wastes in the mining and metallurgical industry.
