Where gold is located?
The gold was found in the oaks of the creek, which was formed before the Cambrian era to the present day, where there were alloys of silver and gold known as electrons, and these are found in different degrees in color, in gold and silver, depending on the proportion of containing the elements, Very small particles formed in rocks along with quartz or calcite sulphite, known as pseudo-gold, and with tellurium, rarely exist with copper, lead, and mercury alloys. Metals were found in the form of flakes, nuggets at the end of silt deposits, and microbes Played an important role in the formation of R. Gold is found in these regions. The mineral is also present in the sea and ocean world. It was found in the Atlantic Ocean and the Eastern Pacific at different concentrations. Gold concentrations in the South were equal to 50 fmol / L and also found in the deep waters of the White Sea But at a slightly higher concentration with concentrations of 100-150 fmol / L.
Since 1880, South Africa has been one of the largest exporters of gold around the world. It produced about 1480 tons of gold per year at the time. In 2007, China started producing 276 tons of gold annually. In that year it was the most productive country in the world, As of 2013, China ranks first, followed by Australia, the United States, Russia, Peru and South Africa. There are many important countries producing khat, Burkina Faso, Mali, Indonesia, and Uzbekistan. Johannesburg which is located in South Africa to detect mines Gold is located on the northern and northwestern fringes of the Wetwatersrand basin. The area consists of rocks between 5 and 7 km in diameter and gold is found in six regions in the north and northwest.
