Apr 14 2015 We USAF active duty members in Alaska back in the late 1950s did a lot of stupid things in our quest for gold. When panning for gold the remaining concentrate of heavy sands and fine gold presented a problemseparating the gold from the sand was a tedious undertaking with tweasers kind of like picking fly chit out of pepper.
Underground mining occurs if the ore grade or quality is sufficient to justify more targeted mining. The room-and-pillar method involves extracting the ore by carving a series of rooms while leaving pillars of ore to support the mine roof. 7.1.2 Beneficiation Precious metals may be recovered from the gold ore or from refining processes of base
