Borehole Mining Springerlink

Borehole mining is a general term for any process in which the wanted mineral or metal values of a deposit are fluidied in place by some means and removed from the deposit via borehole. Researchers have proposed Shock and Conley 1974; Anon. 1974a that it should supplant the accepted but narrower term chemical mining which implies that the wanted values are dissolved in a reagent that
