THE BASIC PROCESSES OF GOLD RECOVERY INTRODUCTION. Man has held a fascination with recovering and acquiring gold almost since the beginning of time.
A gold mill houses the equipment necessary to remove gold from the surrounding waste rock, either by concentrating it or by mechanically separating it.
Summary. Historically, the majority of gold was mined from quot;placer depositsquot;, where gold has settled out of an existing or ancient waterway downstream of where nuggets had eroded out of rock outcrops.Some early miners also used an early form of hardrock mining, digging solid veins of gold out of rock, where mineralized water had deposited
