How to melt gold?


WHEN RECYCLING gold, or gold ore excavating ore te essential process in gold is chemically dissolve the gold. You should know that gold is rare metal, precious and highly valued. In obtaining gold from ore require considerable amounts of raw materials. FOR ONE GRAM PURE GOLD NEED MORE TONS excavated ore from which it gets the gold.

To extract gold from raw materials and get the required purity of the gold pieces you need to use a chemical process. Because of its features gold is very durable metal, among other difficult soluble, antikorozivan and excellent conductor. To extract gold from raw material processing needed to use the well known method of melting gold using acid 'aqua regia' or translated Aqua regia.

Aqua regia word itself tells us what kind of fluid it is. Specifically aqua regia is one of the few acids 'acid blend' that can dissolve the gold. Aqua regia is essentially a combination of the two acids, none of which can dissolve gold independently - without the operation of the other acid.

If you try to dissolve gold in hydrochloric acid, the reaction with the gold would not see anything. To get the reaction we want to add more hydrochloric acid and nitric acid. We now have a blend of 'aqua regia' with us known as aqua regia, which oxidizes the gold and build a chemical compound HAuCl4.

If you have a gold piece immersed in a certain amount of aqua regia acid reaction can be seen with the gold. Specifically, for a time the gold will melt and 'disappear' into the liquid. Extracting gold from the liquid that has a chemical composition of HAuCl4 is a process that actually get 99% pure gold powder. Extracting gold atom from aqua regia is done using metabisulphite powder, and exactly how the process looks to see the video. On this link is shown in detail process of separating the gold from aqua regia.

Treatment process, separation of gold from impurities can be done in case you are involved in recycling gold. If you have any recyclable waste, such as gold coated metal conductors and the like, using zaltotopke extract and produce gold in ga purity 99% and more.

Working with acids is dangerous so be careful and know how to use them. You should stick to the precautions and have proper protective clothing. Place of work needs to be equipped to deal with hazardous chemicals. Gold recycling
