Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.
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.
Gold demand of 973.5t was the lowest Q1 since 2008. The main cause was a fall in investment demand for gold bars and gold-backed ETFs, partly due to range-bound gold prices. Jewellery demand was steady at 487.7t, as growth in China and the US compensated for weaker Indian demand. Central banks bought 116.5t of gold (+42% y-o-y).

one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called 'beneficiation.' Milling is one of the most costly ...
