View MoreGold compounds include potassium dicyanoacid K [Au (CN) 2] used in gold plating bath and chloroauric acid, HAuCl4, which are used as intermediates for the production of other gold compounds and occasionally for ceramic coloring. Gold salt is also used as an anti-inflammatory drug for rheumatoid arthritis.
View MoreVarious aspects of gold refining process are introduced, including step-by-step methods, practices and technologies.
View MoreTo do this, we need to make a test chemical called stannous chloride or sn-cl2, which is essential to determine how much gold is left in the second bath. To do this, you need a beaker, and about 30 ml or wall acid.
View MoreIt is generally believed that dissolving base metals with gold will increase the steps of the refining process and consume more chemicals. If handled properly, people can achieve good results and produce high purity gold and silver, up to 99.95%. This article has videos embedded in youtube, ranging from 14K scrap gold jewelry to 24K pure gold.
View MoreIn general, gold can be used using these two most famous gold refining processes: aqua regia and gold electrolysis. Both techniques can be used to separate gold from other metals. This is because a small piece of other metal in gold can change its nature and value. One

View MoreYour gold recovery tools include... 500 g bottle of sodium pyrosulfite (nc-10319). 500 g urea bottle (nc-2620). Sodium metabisulfite is usually used to precipitate dissolved gold from aqua regia and gold chloride solutions. When it is dissolved in water, it produces sulfur dioxide gas, which is very effective in precipitating gold from the solution.
