mining wikipedia placer mining is the technique by which gold that has accumulated in a placer deposit is extracted placer deposits are composed of relatively loose material that makes tunneling difficult and so most means of extracting it involve the use of water or dredging Gold Mining Methods Summary historically the majority of gold was mined from quotplacer depositsquot where gold has settled out of an existing or ancient waterway downstream of where nuggets had eroded out of rock outcropssome early miners also used an early form of hardrock mining digging solid veins of gold out of rock where mineralized water had deposited it over thousands of years Gold History Of Use Mining Prospecting Assay Amp Production Uses of gold in the ancient world gold was among the first metals
