Pruebas comparativas de flotación, cianuración y concentración gravimétrica centrifuga de los relaves de la Planta de Beneficio “PITUCA II” sector Zamora

Abstract

The tailings from the mining concession "Pituca II" Zamora sector, were subjected to three metallurgical testing flotation, gravity concentration and cyanidation centrifuge by Knelson. To perform the respective tests was grinding to release the Au, since the mesh valued told us a higher percentage of Au in the mesh # 120 with a D80 = 158 um before subjecting the material to grinding conditions are not optimal to perform metallurgical testing, since it became a grinding 15 minutes in which he obtained a D80 of 95 microns, with optimal conditions for metallurgical testing. After making the appropriate testing under standard metallurgical balances respective done to compare and thus know which one is the most efficient for the recovery of Au, coming to see the end that the most efficient test is cyanidation with a percentage recovery of 83%. quantifying the sludge in which indicates that has a volume = 334,37m3 = 735,61Tn was performed.
