Abstract
In the present work, a study of the mineralogical characteristics of the copper mineral from the San Rafael de Belén deposit was carried out, in order to investigate and identify significant variables for efficient recovery and achieve an optimal degree of sulfide copper concentrate through foam flotation. The experimental tests showed that with a combination of factors (% solids, pH, collector: Aerofloat 25 and flotation time) a recovery greater than 90% of sulfided copper is achieved. The variable characterization tests used the Plackett-Burman experimental design to evaluate the factors involved in the process. It was found that the variables with the highest incidence are the percentage of solids and dosage of the Aeroflotat-25 collector; Finally, a first-order mathematical model was determined to predict the recovery of the sulfide copper mineral present in the deposit.
