Many gold ores and concentrates contain fine grained gold locked within sulphide minerals, such as pyrite and/or arsenopyrite, unavailable for recovery by conventional leaching. In Sherritt’s gold process, the sulphide and arsenide minerals are completely oxidized by pressure oxidation, thereby liberating the gold.

As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore. But, currently there are very few deposits left that contain ores suitable for gold recovery strictly by this method.

The driving factor in development of an efficient gold process flowsheet is to understand the deportment of gold and its grain size. Typically, gold occurs as native gold but processing is driven by the host mineralogy. Gold with grain size greater than 0.15mm can be readily recovered using gravity concentration.

Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and. Hashing (extraction/recovery) In the context of flowsheet selection, the bashing and mashing stages are relatively straightforward.

Step 2: Cleaning. After the surface is prepared, and a visual inspection is done, electrocleaning, ultrasonic cleaning, or steaming, usually takes place. This second, deeper, cleaning step must follow to ensure metal is free of oils and dirt, which helps produce superior plating results.

At current gold prices this is worth about $400. Both smelter treatment charges and oxidation or bio-leach costs are around $200/t of concentrate so a minimum GSR for effective downstream processing is 0.5, but clearly this is a function of gold price.

In sheet metal forming practice, we distinguish five basic modes of deformation: • STRETCHING: The material is expanded in both directions. This mode of deformation is found mostly on smooth bottoms of shallow parts and in hydroforming processes. • DRAWING: This mode is typical the material flow from the flange towards the
