As upside potential B2Gold considers that part of the stockpiled low and medium grade ore can potentially be processed in the ROM feed at marginal cost, as the processing plant was designed for the 4 Mtpa nameplate ...
Ore processing Waihi Gold. The processing plant has the capacity to treat up to 1.25 million tonnes of ore per annum. These stages can be described under three main headings: grinding and size classification to reduce the ore down to a fine particle size; leaching and adsorption to extract the precious metals from the rock
Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.
Raw materials through crushing, grinding processing, when the particle size of 200 mesh content reach to 90% - 95%, stir and cyanide the slurry, then leaching, activated carbon counter current adsorption, gold loaded carbon desorption electrolysis etc steps, the finished product is gold ingot.
If the ore contains some particle gold, the gravity separation process should also be set in the first stage of grinding and grading unit. 3. Thickening. The overflow slurry of classification is only 18-25%, if directly leaching will result in excessive energy cost and reagent consumption. Therefore, thickening is .
The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in the leaching process.
The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation.

The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately 0.8 gram per tonne gold and 0.11 per cent copper.

In simple ores, the amenability of the composite to the recovery influenced by the gold minerals distribution, gold particle size, degree of oxidation and occurrence. Sometimes, gold deposits are not exploited due to the mineral was not well understood and the process was not able to give high recoveries, or at least, expected recoveries.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
