    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 Gold panning is mostly a manual technique of separating goldMining is the extraction of economically v aluable minerals or other geological materials from the e arth surface It may be from an ore body, lode, vein, seam, reef or placer deposits Since the(PDF) AN OVERVIEW OF MINING METHODS ResearchGateShrinkage stoping is a mining method used for steeply dipping, narrower ore bodies with self supporting walls and ore It is an overhand mining method that relies on broken ore being left in the stope to be used as the “working floor” and to support the walls During the mining cycle, only 30 – 35% of the ore blasted is extracted beingShrinkage stoping QueensMineDesignWiki
