ResumenThe purpose of this paper presented at RECIMAT-09 is to address, briefly and as clearly as possible, expectations which may have arisen from the basic and applied research regarding the increasing problem of pollution caused by arsenic derived from copper metallurgy. In addition to the metallurgical problem which has not been resolved on an industrial scale, there are difficulties with the environment, with energy variables (both exothermic and endothermic reactions) and materials or by-products related to nanoscience and nanotechnology. This type of product may originate from the emergence of new solid phases due to condensation vapour. Finally, since large amounts of high quality AS2O3 metal are being produced naturally through this process, this would be a good time to look at the situation as a real opportunity rather than a problem that must be avoided. We need think only about what it would mean to lower costs and thus prices in the electrical industry - electronic: semiconductor and photovoltaic solar energy, mass and the economic feasibility of the chalcogens (chemical combinations between elements of the III and VI columns in the Periodic Chart) [1].
