Concentration By Gravimetry Of A Sedex-Type Deposit Of (Au-Pt)
Abstract
In this work the characterization and gravimetric concentration of the precious metals contained in a SEDEX type mineral, from the Molango region in the state of Hidalgo, Mexico, was performed, said mineral presented an average chemical composition in weight% 32.72 of Si, 4.92 of Al, 0.62 of Fe, 0.70 of Mn, 1.25 of K, 57.07 of C, 0.61 of Na, 0.2 of Mg, 0.21 of Ti and 0.34 g/ton of Pt, 0.71 g/ton of Pd, 0.23 g/ton of Ag y 7.67 g/ton of Au.; Likewise, it presents as majority mineralogical phases: ilmenite, calcopirite, quartz, mogonite, argentopirite, moscovite. On the other hand, the results of gravimetric concentration revealed that the greatest recoveries of these metal concentrates occur between 80 to 150 meshes with recovery ranges of 37 to 55 g of metallic elements with contents of 23% Au and 3% Pt.
