Flotación de oro, material de la relavera comunitaria El Tablón procedente del distrito minero Portovelo-Zaruma, usando reactivos químicos amigables con el medio ambiente

Abstract

Abstract: The present research work called "Flotation of gold, material from the community tailings" El Tablon from the Portovelo-Zaruma mining district "consists of three phases, the first phase includes grinding tests to achieve the appropriate grain sizes (76 μm , 66 μm) (# 200, # 220 mesh), later eight differential metallurgical floatation tests were carried out, varying the pH in a range from 7 to 9, also alternating the use of the Ar-1404, Ar-1242 collector. In the second stage of metallurgical flotations, the pH (7) of the liquid flotation medium is fixed, the granulometry varies from # 200 to # 220 mesh; finding the best result in the range of pH (7) with a yield of 97.50% with the granulometry in the # 200 mesh. The third phase was carried out with variants in the size of the grain and the collectors used Dithiophosphates Ar-1404 and Ar-1242, another variant is the pH range (9.10), obtaining 93.7% as the best yield using the Ar-1242 collector with a granulometry in the # 200 mesh.
