Extracting Gold|HowStuffWorks

Removing thegold-bearing rock from the ground is just the first step. To isolate puregold,miningcompanies use a complexextraction process. The first step in thisprocessis breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Innovations: Introduction toCopper:Mining&Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metalliccopperfrom the ore. By far the greatest proportion ofcopperis extracted from the sulfides ofcopper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
