Reef gold is imbedded in quartz rock, which has to be crushed to release the gold caught in the seams.Gold extraction processIn this gold extraction case, use Zinc powder 80 grams or 4 times of quantity of gold. And hope to have gold 20 grams. The first time, we use Zinc powder 50 grams. The second time, we use Zinc powder 30 grams, Potassium Hydroxide 110 grams per a liter of water. The first silt, we use Potassium Hydroxide 80 grams.
