Gravitational Gold Washing Method for Alluvial Gold Fields

Alluvial gold ore are mainly mined from land surface or river or underground. There are various types of gold raw material: alluvial gold, placer gold, sand gold, river gold, gold tailing, etc. The main gold beneficiation process includes feeding, washing, sieving, rough separation, final concentration and refining. Because the gold density is ...

The electromagnetic spectrum is a distribution of energy over specific wavelengths. When this energy is emitted by a luminous object, it can be detected over great distances. Through the use of instrumentation, the technique detects this energy reflected and emitted from the earth's surface materials such as minerals, vegetation, soils, ice, water and rocks, in selected wavelengths.
