Hydrometallurgical process of producing FERRIC SULFATE solutions at a concentration of Iron (iii) greater than 20 g / l, and contained less than 1 g / l of Silicon and other impurities from fayaliticas slag

摘要

This process is carried out continuously in three Sequential Stages: acid leaching slag fayaliticas blasted and classified in a 100% of particles with a diameter greater than 0.1 cm; removal of impurities in SiliconAluminum and other impurities in the leaching Liquid percolated through the previous Stage specific Thermal coagulation and precipitation of Colloidal silica, or alternatively the Neutralization by Lime slurry; and bioxiliviacion the ferrous solution in a bioreactor
