extracting gold powder in quartz sandstone

Extracting gold from rock. We want pure gold, but gold-bearing rocks include lots of other materials such as quartz, calcite and the sulfides of other metals We need to separate the gold from everything else in the rock so the rock needs to be treated in some way In New Zealand we chiselled some rocks from an outcrop near a small creek...
