Gold mining

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 dredgingThe selection of underground mining methods is primarily based on the geological/spatial setting of the deposit Candidate methods can therefore be chosen and ranked based on estimated operational/capital costs, production rates, availability of labors and materials/equipments, and environmental considerations The method offering the most reasonable and optimized combination of safe ty.
