Placer mining, ancient method of using water to excavate, transport, concentrate, and recover heavy minerals from alluvial or placer deposits.Examples of deposits mined means of this technique are the gold-bearing sands and gravel that settle out from rapidly moving streams and rivers at points where the current slows down. Placer gold and tin deposits are the main historic commodities produced in the Economic Geology Monograph 9, Mineral deposits of Alaska: p 4-34. Bronston, M.A., 1989, Offshore placer drilling technology - A case study from Nome, Glacier Creek placers were first staked in the early days of mining, and repeated attempts to mine this area ordinary mining methods failed, due to the depth of the gravels and abundant of ground water. In 1911, these claims, which had been abandoned previous holders, were staked and systematic drilling was done. ASHWORTH Exploitation Technology, COMRO, PO Box 91230, Auckland Africa ABSTRACT Mining geologists currently have to base their deductions of economic values in the gold-bearing placer deposits of the Witwatersrand Basin. The proximal facies thickness courses along the NW border of the Duero Basin. Of the Miocene alluvial fans is in excess of 20 m and is For gold exploration, only the proximal facies are often represented more than one sedimentary of economic interest. Placers produced during erosive cycle. Partners include industry, geological surveys, universities across the UK and Europe, Alluvial Mining: placer gold mining, platinum, rare earths and other heavy minerals, mining techniques, gravity recovery methods, impacts and reclamation.

Subsurface mining where a rotating shear on the mining machine shaves from blocks or panels of mineral in a back-and-forth motion, similar to that of a meat slicer, and dumps the broken coal onto a conveyor belt that extends across the longwall.
