In this video, we will explain another method for examining some gold-bearing samples, which contain types of black, brown or red dust, or all of them together. The examination method is to grind the sample well, then wash. If the sample does not contain sulfates, and if it contains sulfates, it must first Roast well without washing, and if it contains iron, it must be removed with a magnet.
Then we melt a little of the sample with the same amount of copper, and a little borax. The sample must be melted for several hours.
Hence, we make sure that this type contains gold
When the yellowing of gold appears with copper.
Then there are other operations and calculations that must be done to obtain pure gold, and operations to separate copper from gold. We will explain this in another video, God willing.
