  • How to Make Gold Bar, Nugget/Bullion Casting Machine for Sale

    The first step in the process of making gold bars (if gold is being processed form gold ore) is that the ore must be extracted from the ground After a goldbearing deposit has been located, the gold is extracted by mining In old times hydraulic mining was often performed – using high pressure water jets to mine, move and separate gold from deposits However in modernPressure 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 POX has been used since 1985 when it was first put intoPressure Oxidation Caldera Engineering31/8/2020· Open pit mines also process roughly five times the amount of ore at an average grade of around 105 g/t Au for the population evaluated, versus 325 g/t Au for underground mines,” says S&PNearly a tonne of CO2 emitted per ounce of gold produced
