Underground Gold Processing Plant
underground gold processing plant
Ore processing Waihi Gold. Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous
Gold mining Wikipedia
Late 15th and early 16th century mining techniques, De re metallica It is impossible to know the exact date that humans first began to mine gold, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria.The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 7000 years old.
