Introduction
I love knowledge knowledge and enjoy learning. I am a biologist and I have a Master's degree in molecular biology and bioinformatics. At present, I am working as an associate researcher for a Biotechnology Institute. With my background, you may probably wonder what biology has to do with gold recovery since in the first place; this material is all about how to recover gold. Well, it's pretty simple. Here's how it happened. Three years ago I wrote a research project about looking for strategies on bio-refining gold using bacteria. As I explored the gold market I found that the principal consumers for this precious metal were IT companies. Reading about catalysis I found that computer devices and also some car parts need precious metals such as gold to speed up its physicochemical capabilities. Yes, that is right; computer devices, car parts and other electronic devices contain small amounts of gold, of gold, silver and palladium. After discovering this extensive use of gold and other metals in the market, I then decided to put my bio-refining techniques into this manual. I want to share with you several protocols I use for gold recovery using chemical reactions, which I believe, can be of great use and help for you as well. All the steps in each protocol involve the use of different types of scrap and were safely tested in the laboratory. The protocols I have explained here are simple to understand and simple to master. You can follow all of these protocols right in the comfort of your own home. So, sit back, relax and let me show you how you can refine gold from scrap metal. Enjoy,
Gold refining protocol I a sample 1. Use a hammer to break the scrap and clean it using water. It is much better if you work with little pieces. 2. Place the scraps in a beaker or a plastic container and add nitric solution (A). Wait for the scraps of gold and pins to fall down at the bottom of the beaker. Because this takes a day or two, you can speed it up by heating the solution even on a coffee pot and after 15-20 minutes repeat the process until the solution becomes clear; wash the scrap with clean water. Here, we are cleaning the scrap from those metals that react with nitric acid (copper for example). Remember neutralize the used solution before discharge. ( Solution A: nitric acid: water 1:1 v/v ) 3. Prepare the aqua regia solution (1 volume of nitric acid per 3 volumes of hydrochloride hydrochloride acid). It can be prepared in the same beaker that already contains the cleaned scrap. Put HCL into the beaker until it covers all the scraps. Slowly add nitric acid until the required volume is completely poured and wait for around 40 minutes. The more gold you have the more brown-yellow the solution becomes! 4. Add three water volumes to the solution to neutralize the acid (very important). After the acid has been neutralized, filtrate it using a dense cloth. The cloth should be dense enough so that all the organic dirt is filtered. Recover the solution in a clean new beaker. 5. Add zinc powder until the solution gives a black-grey color and appears like a dark dust. Wait for 15 minutes to let the dust fall down. Recover the deposition (gold and zinc) and do step one of this protocol again. 6. Wash the dust dust several times using water. Boil the solution. Slowly add sulfuric acid with precaution as it reacts violently with water. Discharge the solution and repeat the washing cycle again.
Finally, recover the final product that should be black red-dust in color. This is now your gold.
I have to mention that this is a free protocol I want to share with you as a thankful for visit my site although there are better approaches to obtain a cleaner gold to sell it online. I strong recommend obtaining my report NOW.
