To activate the solution you want to add your Hydrogen peroxide 3 5% solution in a 2 to 1 ratio. two parts muratic acid to one part hydrogen peroxide. after the Peroxide has been added to your muratic acid the mixture should start to bubble, and the base metals should begin to dissolve.

May 22, 2018#0183;#32;Pour off the slag into a heat resistant container. The liquid will be too thick to pour once it is cold. Add in some borax to thin out the liquid. When the liquid cools, chip off the glass which will have floated to the top during the cooling process and there is your gold, smelted to perfection.

Using a microwave with less than 1200 wattage is not recommended. Allow at least 1 inch space between the top of the kiln and the ceiling of the inside of your microwave oven. Allow the microwave to cool at least 20 minutes between firings. Keep microwave door

Metallurgical ContentHazardous ChemicalsHow to extract gold by smeltingHOW TO EXTRACT GOLD FROM THE SMELTINGThumbnails gold extracted In smelting and melting for pure gold, that is, gold of 24kt. value is very much too soft for jewelry purposes and it is therefore always alloyed with other metals to increase its hardness and resistance to wear. For the same reason pure silver is seldom used
Mar 28, 2017#0183;#32;The electrolyte solution you made will dissolve the gold from the scrap, and the positive charge in the gold will cause it to attract to the negatively charged steel. All of the gold in the electronics scrap will form onto the steel, where it can be peeled off and set aside until you have enough to refine.
Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about percent purity. The Wohlwill process increases purity to about percent by electrolysis.
Using a rare earth magnet, we can physically pull them away from the gold. It is very important to get an extremely powerful rare earth magnet, because although magnetite is highly magnetic, hematite is only slightly magnetic. The added power of one of these extra
Feb 24, 2012#0183;#32;With the quantity of gold in this tutorial, using the plastic pipette, I added 5 drops of nitric and 15 drops of hydrochloric making a 1:3 mixture of Aqua Regia. Immediately the gold starts to dissolve and the liquid starts to bubble and turn a nice yellow colour. This is a good sign that almost all contaminants have been removed previously.
The alloy consisting of gold and other metals is introduced/fed into the Aqua Regia system after it has been granulated and heated in an Aqua Regia solution. II. Treat the solution of gold + other metals with a reducing agent (sodium metabisulfite) and filter. III.

The flux lowers the melting temperature of gold, making the process somewhat easier to complete, and the lead helps to collect the pure gold from the alloy. The Refiner Heats the Sample This mixture of gold and other additives is then heated and melted at a temperature between
