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.

A rocking motion provides the movement of water needed to separate gold in placer material from gravity. Hard rock mining. Hard rock gold mining extracts gold in rock instead of fragments in loose sediment, producing most of the gold in the world. Open-pit mining is sometimes used, for example in central Alaska’s Fort Knox Mine.

Gold Mining Methods. There are several ways to mine for gold. Some methods highlight old-time techniques, while others embrace the use of modern Dredging - Many miners use suction dredges. These are powerful vacuum-type suction hoses that place materials on a floating recovery system.

Because the materials of interest are located on the same geographic features that are hotbeds for life, any form of mining will disrupt active habitats. A number of studies have been done in an attempt to understand exactly what the consequences would be, based on simulated experiments in the ocean.

This study investigated the use of Philex copper-gold mine tailings (PCGMT) in roller compacted concrete (RCC) production, a mining waste material consisting of finely grinded siliceous particles was obtained from Tailings Pond number 2 (TP2) of a Philippine copper and gold mining company.

Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in northeastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts.
