Black sands in Egypt are beach placers deposited from the Nile stream reaching the Mediterranean Sea at river mouth Floods associated with pluvial periods which prevailed in Egypt during Pleistocene may have caused erosion of the source rocks and liberated heavy minerals including monazite Dawood and Abd El Naby 2007
Chemical on black sand it takes a lot and you have to process out the iron oxides before you can get to the gold I have done this with warm hcl it quickly quits working as the iron in solution elevates I have a water cooled condenser and supply enough heat to force force the reaction allong condensing the evaporated HCL when sands are
gold processing preparation of the ore for use in various For thousands of years the word gold has connoted something of beauty or value These images are derived from two properties of gold its colour and its chemical colour of gold is due to the electronic structure of the gold atom which absorbs electromagnetic radiation with wavelengths less than
If there is only a small amount of gold present in a large amount of black sand it may not be worth the effort to extract it However if a sizable amount of gold is present in the black sand and it can be separated using a simple and inexpensive process like sifting it may be worth the effort to extract the gold
