The goal of leaching is to push the reaction to the right ie; consume the reactants to produce the gold complex in solution. Therefore to leach the gold out of the ore and into solution, cyanide, and oxygen must be added to the slurry. Lime is added to the grinding circuit to modify the pH of the slurry to
Of the numerous major gold mining operations around the world, most utilize a primary crushing circuit which flows into a SAG mill circuit and then a ball mill circuit. The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed rates.
Slurry from the grinding circuit, at approximately 35% solids and 8085% passing 135 mm is pumped to three thickeners. Thickener underflow, at approximately 54% w/w solids, is pumped to a train of four acidulation tanks. Sulfuric acid is added to the slurry to destroy sufficient carbonate prior to entering the autoclave circuit. Process air is also injected into the acidulation tanks to aid

Designing a leach circuit should consider both orespecific factors as well as factors involving the interaction between the ore and process equipment. Achieving the optimum leach performance involves combining operating parameters, such as grind size, residence time, chemical conditions (reagent addition levels, temperature, etc.), most of which interact with each other.
leaching is being developed for implementation at Newcrests Telfer Gold Mine in Western Australia to facilitate a change in circuit design that would then allow for increased concentrations of soluble copper to be tolerated in an expanded gold cyanidation circuit

The mixing of solids suspended in a fluid medium is still largely an art. The development of fundamental laws governing the operation is complicated by the large number of variables involved, some of which can hardly be evaluated in mathematical terms. Practical studies of the circulation patterns of the more common types of agitators are to be found in chemical engineering literature. In one
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the
tonnage (quantity of ore available for leaching) to justify the complexity of design, and higher capital cost as compared to cyanide heap leach methods. A gold mill can be divided into 4 major areas: ore mining and size reduction, leaching, gold recovery, and tailings disposal. Once the ore is removed from the ground it is crushed
