Karat24 Gold

  Amazing Right? Yes, in fact it is possible. The total amount of gold and other precious metals dissolved in seawater is truly incredible.  It has been estimated that we have mined more than 5 billion troy ounces of gold since mining began some 6,000 years ago.  By comparison, the concentration of gold in seawater is, according to scientific estimates, that the oceans contain about 25 billion troy ounces, and that this amount is constantly increasing as more gold leaves the earth's mantle. There are several ways to collect this gold, and some companies have trials underway. Distillation would be one method: basically distilling seawater and refining the residue.  This is uneconomical as the energy required to boil the water is considerable, although potentially a product of desalination plants with additional stages. Besides gold, practically all natural elements dissolve in seawater, to some extent. Now there is a more exciting and potentially inexpensive solution,...

  Precious metal refining refers to the separation of precious metals from materials containing noble metals. These materials are chemically called minerals or scrap.  The most precious metals include gold and silver. These two metals have a very strong position in the development of any nation. So, improvements in its refinement process are the topic that most interests alchemists and metal smiths.  Therefore, on a commercial scale, methods are employed that are economically manageable and have reduced chances of loss of precious metals during the refining process. The commercial refining process is a multi-step process. The first and most important step is the receipt of the sample. The source of the sample is of vital importance. Many geologists predict the potential percentage of the precious metal in scrap. The sample from that location is delivered to the refining plants. When the sample is received at the refineries, it is weighed with the standardized calibrated b...
