Boddington is one of Australia's largest producing gold mines. The Project is owned and operated by a joint venture (JV) between two indirectly whollyowned Australian subsidiaries, Newmont Boddington Pty Ltd (66 and 2/3% interest in the Project) and Saddleback Investments Pty Ltd (Saddleback) [33 and 1/3% interest in the Project]. The manager ...
The DeGrussa Copper Mine commenced commissioning of its 1.5Mtpa concentrator in September 2012. During its first 18 months of operation, the milling circuit experienced numerous issues. The majority of these problems originated from the very fine feed particle size distribution fed into the processing plant.

Higher mine production rates may be possible, subject to further studies. At throughput rates of 34 Mt/y, gold recovery improvements from Stages 1 and 2 are expected to achieve LOM gold recoveries of 80.3% and LOM copper recoveries of 85.2% compared to Stage 1 baselines of 76.8% for gold and 82.5% for copper.
Gold Mining Operation: 10 - 30 years. The gold mining operation stage represents the productive life of a mine, during which ore is extracted and processed into gold. Processing involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a ...
If the locked gold measures between 2 and 20 μm, ultra-fine grinding can be employed, which involves intensive milling and particle disintegration (Celep et al., 2011; Corrans and Angove, 1991).
This 1-day course has been designed for engineers, geologists, mineralogists, environmental scientists, plant operators, marketers, financial advisors and those either dealing with mineral processing (extractive metallurgy) or wanting a better understanding of …
Data collected from the AMIRA P420E Industry Practices Survey on mine production, gold production and cyanide consumption can also be used to demonstrate the potential of preconcentration and coarse gangue rejection for gold ores (Eksteen, 2015).Fig. 2 plots the energy consumption per unit of gold produced against head grade. The specific …
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 Saudi Arabian operation reports that particle ore sorting allows it to use 45% less water. Its flotation plant is 40% smaller, its crushing and milling costs are significant lower – 75% and 45%, respectively – and it saves $10 million per year on reagents.
Australia has recently experienced a surge in silicosis cases as a result of growth in the manufactured stone industry. In 2019, there were an estimated 350 cases of silicosis in Australia, with 100 cases identified between September and December .
Victoria has produced over 2400 tonnes of gold which is 32 per cent of all the gold mined in Australia and almost 2 per cent of all the gold ever mined globally. On a yield per area basis, Victoria has produced an average of 10.8 kilograms of gold per kilometre squared – which is greater than any other Australian state.
Free gold is that which can be easily liberated and is unbound to other minerals. Free gold can be rapidly recovered in high amounts using gravity concentration methods. Traditionally, simply exploiting the high specific gravity of free gold for recovery required little energy and was profit-generating.. Today, however, more milling energy is consumed due to the change in …

gold processing - gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …
Australia's largest gold mine has been owned by Newmont since 2009, when it purchased a controlling share in the project from AngloGold Ashanti and Newcrest. The company has since invested heavily in the Western Australian open pit mine, which reached two million ounces of gold produced by 2012, and ramped up production to 787,000oz of gold ...
Newcrest's Cadia Valley operation took out top spot as Australia's largest gold producer with 218,891 oz for the quarter, followed by Newmont's Boddington (155,000 oz) then Newmont's Tanami operation (131,000 oz).
Although there are various leaching techniques for free-milling ores, the main technique in Australia, North America, and South Africa is agitation cyanide leaching. Gold recovery is then attained through carbon-in-leach (CIL) or carbon-in-pulp (CIP) methods (Brooy, 1994). The figure below from Lima (2007) shows a typical CIL/ CIP process.
The cement industry is the main supplier of raw materials for the production of concrete and reinforced concrete. For grinding cement, two types of mills are used - ball and roller.
Alumina Balls and Satellites. Union Process is the one source for 90%, 94%, 99.5% and 99.9% alumina media. 90% alumina is available in satellites and rod/cylinders. 94% alumina balls have excellent wear resistance with higher impact strength to save running costs with less contamination.

Gold processing 101. Amidst the general fall in metal prices over the last few years, the gold price has remained comparatively stable in the US$1,000-1,250/oz range. Gold bulls were disappointed that the price did not break through the $2,000/oz ceiling; nevertheless the current stable price run has helped to maintain a strong interest in gold ...
