Validación de un método voltamperométrico para la determinación de arsénico en concentrado aurífero en planta de beneficio Metalesa periodo 2022.

Abstract

Heavy metals are found naturally on the earth's crust, among them we can mention As, which in high concentrations is extremely toxic and harmful to human health. On the other hand, mining plays a fundamental role in As contamination, since this element is found in a greater proportion in hydrometallurgical processes, among which we can mention flotation, which consists of concentrating most of the mineral of interest. by the general use of air or other reagents. Likewise, some of the different mining companies, present in the province of Azuay, in the Ponce Enríquez canton, are subject to penalties for the existence of this metal in their concentrates, causing incalculable losses for the country and for the company in question. Some of the techniques used for the determination of As are Atomic Absorption Spectroscopy, which has been used for some years in the Ponce Enríquez canton, but this technique is not one hundred percent effective for the determination of the metal, some The shortcomings of this technique are mainly that it uses expensive reagents, the low precision of the method, and the high cost of the equipment.
