Resumen
[Resumen] Se estudia el proeeso de flotacion Pirita-Scheelita en tubo de Hallmmond,y su aplicacion en una celda de flotacion monolaminar. El preacondicionamiento de la superficie de los cristales de Pirita,para eliminar los grupos hidrofilicos permite obtener rendimientos cercanos al l00%,en la flotacion de pirita con KEX y Aceite de Pino [Abstract] The Golpejas tin deposit consists of several sheets of albite microgranites, more or less circular in shape, that intersect rock materials of the schist-graywacke comp1ex and the over1ying Ordovician and Silurian metasediments. Most frequent1y, the minerals making up the deposit –cassiterite and columbite-tantal ite-- are disseminated in the granite, but ocassionally they also occur in intragranitc quartz veins containing ambl igonite and Cu, Sn, Zn, Ag and Bil sulphides. The albite leucogranite were generated during the final crystalization stage of a highly differentiated magma. They were intruded at a relatively shallow level following the emplacement in depth of a granitic cupola during the second Hercynian, tectonic phase
