Recuperación de oro usando bórax mediante concentración gravimétrica variando el tamaño de grano, trabajando con técnicas amigables con el medio ambiente

Abstract

Abstract: The present research work entitled "Gold recovery using borax by gravimetric concentration varying the grain size, working with environmentally friendly techniques" presented two phases.The first consists of submitting the material to metallurgical tests; starting with gravimetric concentration on a vibrating table, analyzing the influence of particle sizes 75 μm and 63 μm, obtaining values of 3.79 % and 3.23 %; the second test was used to verify the presence of gold in the sample; flotation, acquiring 14. In the mineralogical analysis with X-ray diffraction, I determine the minerals with the highest percentage (anorthoclase, muscovite) and in X-ray fluorescence: silicon oxide(SiO2),alumina(Al2O3);applying the Aerofloat 1238 collector, effective for gold and avoids toxicity to the environment.The second phase aims to mitigate the mercury pollutant with the direct fusion of borax, through the concentrate obtained on the table. The results and interpretation can be found in chapter 4.
