Extracting gold from rock OpenLearn Open University
We used a heavy metal rod (a broken half shaft from a four wheel drive) and smashed the small bits of rock in a saucepan. The rock needed to be powdered for us to get to all the gold within the rock. This is a timeconsuming job because we needed a very fine powder far finer than even sand. We wore out several pairs of gloves in the process. Mercury...
