Pan of Gold

How the gold pan and whether the normal-fed is pure gold ... ..?

Pure gold is only one element of which is called Aurum, In the nature gold will not found as pure gold, but gold in a safe bank surely be pure gold.

Process with a gold paned way set aside from the gold grains of quartz sand them, free gold ore in nature still mixed with other elements such as Sulfur, platinum and silver (silver) and others.

The process of purifying gold, there are two kinds, namely;

The first, called amalgamasi; the process of using the mercury (Hg) ber compound formed amalgam with gold. At first the gold ore melted and filtered, so that only a certain particle size that can be used in the process amalgamasi.

Amalgam made in destillation to mercury (Hg) escape (Hg this element will be used to process the next amalgam), after separated from the Hg elements gold is mixed with soda or borax solution and be heated with a high temperature, the mixture of the remaining left behind will still be bound by the borax or soda, to which only pure gold course, gold is then printed with the form of a rod.

Second, called cyanidation, cyanide this process is done only for the gold ore that is not mixed with the elements sulfur, or clean sulfur from the elements, in this process the gold ore dissolved in a solution or potasium cyanide salt, and then the solution is poured into the tray which has a wheel element zinc (Zn), Zink elements will react with cyanide so that the dough falls pure gold to base of tray cleaned after the new form that is appropriate to print a bar.
