Small scale heap leaching is a possibility it is a process that is worth considering. Many prospectors would just like to know something about are hard rock prospecting and how to find gold veins as well as rich pocket deposits of high grade gold ore.
Feb 21, 2014#0183;#32;There are more than one hundred million people engaged in small scale hard rock mining across the planet. A lot of it is done in a dangerous manner, but is still interesting to see. I am always amazed at how people take what I would call Junk and turn it into functional mining
Smallscale hard rock miners do not have the luxury of a fully equipped industrialgrade mill with flotation and cyanide leaching to process their ore and recover values. We are usually limited by practicality, finances and permitting to a simple crushing and grinding circuit, with a gravity recovery system for the free milling values and value
