This is a piece of gold ore from the famous Witwatersrand gold deposits of South Africa. The ore consists of conglomerate pebbles mostly of quartz, in a sandy matrix, with abundant pyrite in the cement. The gold, which occurs in the cement but not in the pebbles, is closely connected with the pyrite and is not visible to the naked eye.
The crude gold is melted and then treated with chloride. This converts any foreign elements or minerals still in the gold into chloride, which will then naturally drift off the gold. The result of this process is 99.5 percent pure gold. The final step is to cast the gold into electrodes or
Apr 11, 2017 Im thinking that if youre getting 100- or finer gold, dont go above 12 inch down from the top.
