It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions nuggets of native gold weighing up to 50 kilograms are foundthe largest having weighed 92 kilograms. Native gold invariably contains about 0.1 to 4 percent silver. Electrum is a gold-silver alloy containing 20 to 45 percent silver. It varies from pale yellow to silver white in colour and is usually associated with silver sulfide mineral deposits

The impacts of various challenges, including escalating costs, labour availability, and labour utilization on the mining industry, and the gold sector in particular, are quite evident. This is confirmed by EY (2014), who state that productivity on cost and volume bases has been declining since 2000, and various companies have engaged in different cost-cutting exercises. EY (2014) emphasized that the mining industry needs to regain ground lost over the supercycle; innovate to recover/gain competitive advantage; and counteract rising wages, hence the need to boost productivity. This paper discusses trends in productivity for South African gold mines and gold mining companies between 2006 and 2014. Productivity reporting is not yet fully practiced and where done, it is done in silos. This paper aims to provide a guideline to where the South African gold sector stands in terms of productivity, over a time period that captures the impacts of (1) the global financial crisis and (2) labour unrest. The choice of the gold sector was in line with its labour-intensive nature as well as to provide boundaries to the paper

Mining and mineral processing have generally been at the forefront of industrial innovation for millennia and, through development of extraction and refining technologies, were responsible for major improvements in lifestyle, beginning with the Bronze Age and the Iron Age. Copper smelting, for example, began at least 4000 years ago. Until the mid-1800s, most aspects of mining and processing underwent progressive evolutionary improvements in technologies that had been applied successfully for centuries. However, the mineral industry then became a leading participant in the Industrial Revolution with important innovations in underground mining methods, improved gravity concentration equipment, and grinding mills
