Yes, it is possible. For this, all you need to use the right chemicals, methods, and machines. For example, if you want to remove gold from the circuit boards, you can mix 2 parts of muriatic acid into one part of hydrogen peroxide. After a few days, you will find gold floating around the pot. Now, you need to add some borax to the collected gold flakes and heat them using a crucible. This way, you can get the gold.
What temperature can the induction melting furnace reach?
Well, the advanced induction furnaces don’t have any limit to the temperature that they can attain. For example, the melting machines designed to melt gold can easily reach up to 3000-degree C. So, such machines are good for melting different precious metals. When it comes to melting platinum, you can set the temperature at 2000-degree C.
What is the difference between an electric arc furnace and an induction furnace?
Speaking about the electric furnace, it generally functions on a principle where arc generates heat and melts the metals. On the other hand, in the case of an induction arc furnace, the heat is generated using electromagnetic induction. If you compare, you will find that an induction furnace will heat up much faster than an arc furnace. If you want to witness a faster melting process of precious metals, buying an induction furnace will be a perfect option for you. As they are easy to use and high in quality, induction furnaces are widely used in different industrial induction furnaces.
How do you know if it is real gold?
