Gold Recovery Chemicals

Gold Recovery Chemicals Guide for Our Beginners:

If you are new to e-waste recycling and gold recovery then this page is for you. In this guide, I will tell you some basic things, formulas, and some tricks. The reason for this post is that many people could not understand some acid names, formulas, and other gold recovery chemicals. So, I thought about this and did it for those friends, who are new to our recycling family and want to learn about gold recovery and e-waste recycling.In this post, I will show you everything in details step by step. So, Let’s start……..

SMB as a gold recovery chemicals:

gold recovery chemicals Many people ask me about SMB. I thought I start from this. Full form of SMB is Sodium metabisulfite. It is also known as sodium pyrosulfite. Its chemical formula is  Na2S2O5.Its color is white and in powder form. It is used for gold precipitation. There are many companies are manufacturing SMB but BASF company is best. I also use SMB made by this German company. Its result is hundred percent and clear. 1 kg jar can be expensive but if you purchase is 25 kg bag then it will be very cheap. When you open the bag then never leave it open. Fill all SMB powder in airtight jars or plastic bags. If you leave it open then it will not work properly.


HF as a gold recovery chemicals:

hydrofluoric acidFull name of HF is hydrofluoric acid. Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. Its Other names are fluorhydric acid and Hydronium fluoride. It is most danger acid in the world. But in some method of gold recovery, it’s used. So if you are going to use it then be careful because it can harm you. Its price is high. I use its 25 kg cane. Never use this in any glassware because it will dissolve any type of glass. Use only in plastic ware.


What is DMG?

dmg Full name of DMG is dimethylglyoxime. Dimethylglyoxime is a chemical compound described by the formula CH3C(NOH)C(NOH)CH3. Its chemical formula is C4H8N2O2. It is an off white fine powder but if you purchase low quality then it can be solids. Many companies are manufacturing DMG but I recommend you RDH or fluka. These companies have same quality and result. DMG use for palladium precipitation and palladium test in solution.


What is BORAX?

fluxBorax is also known as sodium borate, sodium tetraborate or disodium tetraborate.  Powdered borax is white, consisting of soft colorless crystals that dissolve easily in water. Its chemical formula is Na2B4O7·10H2O. Borax is also used in flux. It helps in gold smelting. Its melting point is 743 °C.

      Thanks for your good words.
      You and use aqua regia but palladium recovery will difficult. You can refine gold with silver. All palladium will dissolve in nitric acid and then you can precipitate palladium with DMG or sodium cyanide.

    I want to know what is the legal way to do this business, because when i start collecting rams i looked for the chemicals to recover gold, then the government (security service) call me for investigate, and they charged me having weapons and and forbidden chemicals.
    Is there any governmental and environmental friendly method to recover gold from e-waste?
    I am not looking for problem, only looking for business.

      You can apply for the license about these chemicals. When you will get the license then you can do this legally.
