Small samples of soil are taken on an expansive grid to identify parts per billion of gold. This method can also be used when geologists want to sample the top of bedrock, which can be 20 or 30 metres below the surface.

Mining Placer, Streams, Alluvial: Placers are unconsolidated deposits of detrital material containing valuable minerals. The natural processes by which they form range from chemical weathering to stream, marine, and wind action. Typical minerals recovered in placers are gold, tin, platinum, diamonds, titaniferous and ferrous iron sands, gemstones (rubies, emeralds, and sapphires), and ...

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.
