Sustainable system for processing fine tailings from mining, low-hardness minerals and industrial, electronic and construction waste, and products obtained therefrom

Abstract

The invention relates to a sustainable system for processing fine tailings from mining, low-hardness minerals and industrial, electronic and construction waste, and products obtained therefrom, for application in the processing of fine tailings from mining, and also for the processing of low-hardness minerals and for the treatment of industrial, electronic and construction waste. This novel design consists of the incorporation of technologies around high-efficiency grinding mills with circulation of hot gases that can raise the process temperature to values of up to 750° C., and pre-concentration systems. This solution makes it possible to improve the recovery of materials of interest, usually metals, and further to promote the pozzolanic activation of the remaining material. This activation will depend on the material and the temperature, and the parameters of the process will be defined taking into account the process and application requirements of the products.
