Alluvial Gold Ore Grade and Exploration – GeologyHere
ALLUVIAL GOLD ORE GRADE. If someone selling gold ore tells you that my gold grade is 3g/m, that's a very low probability. If you could really get 3g/m, you could get 2,400 grams of gold out of 1,000 cubic meters of gold per day. According to the recovery rate of 80%, the formula is 1000 cubic meters ×3g/m ×80% recovery =2400 …
