metal ores, the gold is floated from the base metal tailings.

Arrastras were one of the earlier crushing devices used for pulverizing and removing gold from such ore. Stamp mills, even more labor-intensive albeit more productive, soon followed. An old time prospector's first inkling of a lode occurrence would more than likely have been the discovery of a quartz vein. A rich placer deposit holding coarse ...

Boddington Gold Mine (BGM) is located about 130km south-east of Perth in Western Australia. Boddington Gold Mine (BGM) produced 741,000oz of gold and 69Mlb of copper in 2011. Image courtesy of Calistemon. The ore is initially produced by floatation, which produces copper/gold concentrate with approximately 18% copper.
The raw ore consisted of pyrite, quartz, calcite and mica, with gold being the valuable mineral. It had a gold grade of 4.70g/t, silver grade of 4.63g/t, iron grade of 20.10% and a sulfur grade of 20.55%.
miners do excavate eroded layers of quartz-gold-veins which have a high Bond Index (i.e. are very hard). Hammer mills work in conjunction with hydraulic mining, where ore is disintegrated by high pressure water jets and channeled to feed the mill. The mill product is then concentrated by matted sluice and upgraded by panning.
