• Thiosulphate as an alternative to cyanide for gold processing – issues ...

     · Thiosulphate is an attractive alternative reagent to cyanide for processing gold ores. It is relatively cheap and nontoxic, forms relatively strong gold and silver complexes, and readily leaches gold ores in ammoniacal solutions, alysed by Cu (II). It is particularly suited to carbonaceous ores where the recovery of gold by cyanide is poor.

  • The environmental impact of gold production

    processes were considered: open pit mining to extract the ore, cyanide leaching to extract the gold from ore, carbon adsorption to extract the gold from the cyanide solution and electrolytic refining and chlorination to refine the gold. The LCA assessed production from both nonrefractory ores, which are relatively easy to treat, and refractory ores where the gold is .

  • Ore |

    Uranium mining is already done by chemical leaching and most sulfur is mined by dissolution with hot water pumped into the ground. Once above ground, the ore is typically crushed, pulverized, and then upgraded during a process called beneficiation. Beneficiation separates metal and gangue into concentrates and waste material called tailings.

    Ore sort 'waste' from the Volcanic unit is low grade ore and will be stockpiled for processing later in the mine life. Ore sorting preconcentration increases the mill feed gold and silver grades by 32% and 31% respectively compared to run of mine (ROM) grades. The table below shows ROM grades with ore sort waste removed from the ROM, and the resulting mill feed.

  • The Metallurgy of Cyanide Gold Leaching – An Introduction

    Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

  • Gold extraction

    Gold can be extracted from placer ores using physical separation techniques, particularly through gravity treatment. In modern practice, concentrators use centrifugal force in order to liberate finer gold particles. Major Processing Route For most freemilling ores, a pretreatment process is necessary when chemical recovery is being employed.
