The dump consists of the concentrator tailing discharge, over a period extending to the present date. According to daily samples taken during that period, the copper content is about 0.64 per cent, and the silver 0.48 oz. per ton. The peak of the dump, or the point where the tailing is discharged, carries about 0.75 per cent, copper, while down toward the toe, and where present excavation is taking place, the

    The Metallurgy of Cyanide Gold Leaching An Introduction

    Oct 20, 2014  Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed i.e. the gold is liberated.

    2.1 Leaching. Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 310m high, 10 4 10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 15kg Cum −3.

    Pressure Oxidation

    Overview. Pressure Oxidation (POX) is a process used to extract gold, copper, zinc, molybdenum, and uranium from refractory ore bodies. The POX process utilizes elevated temperatures (roughly 230 degrees Celsius), elevated pressures (roughly 35 bar or 510 psi), and oxygen to liberate the minerals from refractory ores.
