Efecto del tamaño de grano, pH y tipo de colectores en la flotabilidad del mineral de Skarn Aurífero de los Condominios Norte y Sur, del yacimiento minero Nambija

Abstract

The handcrafted mining industry of the deposit Nambija in the south of the Ecuador rejects re-wash with golden laws of economic importance that are wasted by inadequate procedures of exploitation. Re-wash them of the handcrafted plants they were submitted to the process of flotation to recover the rejected gold; in order to improve the laws or golden concentrations, optimizing the rate of recovery of the mineral Skarn of the Condominiums North and South of the mining district Nambija, determining the size of suitable grain, changing the pH to establish if the recovery is major in an acid, basic or neutral way and finally finding the Collector who allows us to have the highest rate of performance.The results were the following ones: with size of grain of 63um, pH of 10.5, and using as collector Aerofloat 25-31, the north condominium obtained a percentage of final recovery of 89.39 % and with size of grain of 75um, pH of 10.5, and using as collector Aerofloat 25-31, the south condominium obtained a percentage of final recovery of 95.16 %.
