Pruebas comparativas de flotación y cianuración del material de la planta Minas Nuevas 1 en el distrito minero Zaruma, a través de parámetros preestablecidos

Abstract

Abstract:The present work was developed in order to compare the results of metallurgical tests with pre-established operating parameters such as grain size of 230 mesh (D80 = 62 µm) and pH of 10 to 11. Comparative tests were carried out between flotation and cyanidation, flotation being a method used for the recovery of mineral from hydrophilic and hydrophobic properties, using reagents such as: collectors, foaming agents and depressants with the addition of air, on the other hand, the cyanidation test It consists of the recovery of gold from leaching using sodium cyanide with a concentration of 1 g / ton for this work. After the corresponding tests, the metallurgical balances and the recovery percentage, it was obtained that the flotation test reached a yield percentage of up to 60,50%, while the cyanidation reached the highest results with a 73,62% yield that was projected at 24 hours of cyanidation, these results are also reflected in the economic analysis carried out where it was obtained that cyanidation exceeds float in earnings with a difference of $ 20.995,99 dollars / month.
