In today's era, everyone's living standards have greatly improved, and various household appliances have already entered millions of households. At the same time, many waste household appliances have also been produced, which has also spawned the waste home appliance recycling industry. So, what's the use of these abandoned appliances that everyone does not want? How did the waste recycling company use these waste appliances to make money?
In fact, these recycled household electrical appliances are different, and some performance is not bad. After being repaired, it will return to the second -hand market. Some electronic components can still be used, and they will be disassembled and sold to the yuan Device. But there are still some damage. Such electrical appliances will be used to extract valuable metals, such as extracting gold.

How is there in waste electrical appliances?
In fact, using waste electrical appliances to extract gold is a very profitable industry. For example, among various electrical appliances, the gold content of the computer is almost the highest. According to statistics, every ton of waste computers can be collected, 300 grams of gold can be extracted from it. Everyone may feel that there are too few 300 grams of one ton, and the weight of two bananas is less than two bananas. In fact, this gold content is dozens of times more than the gold mine content.
The gold mine in Guizhou Chanbao as an example, this big gold Each mining of the mining of ore can only be refined 3-5 grams of gold, and the mining of gold ore not only causes damage to the environment, but also the process is very cumbersome and the cost is particularly high. Therefore, using waste computers to extract gold is much higher than mining. So how do we extract gold from a waste computer?
The method of extracting gold for waste computers
The method of refining gold from waste computers, such as replacement with zinc wire, microbial extraction, strong acid decomposition, etc. I will use strong acid decomposition for example. However, before we give an example, we must remind everyone that the process of extracting gold should be used for a lot of corrosive chemicals. The process is more dangerous. Professional personnel can be operated. Please do not try it privately.
First of all, the waste computers not only contain gold, but also other valuable metals such as copper and silver, as well as some available electronic components, so the first step should be The computer is disassembled and classified. The copper and plastic can be recycled directly, and the dismantled CPU and memory bar are used to refine gold.

The second step, put the CPU and memory bar in a strong acid solution. Among all metals, the stability of gold is the best, so the super -corrosiveness of the strong acid solution can remove other metals on the CPU and memory.
In the corrosion of the strong acid solution, then put the remaining part into a certain part In a characteristic solution (the solution is temporarily confidentially confidential), so as to wait a few hours at this time, you can get gold filtering slag containing gold.
The last step is to be pure. , Get golden compounds, and then melt at high temperature to get gold with high purity. This is several main steps for waste computers to extract gold.
It is necessary to operate by professionals, and the process is more dangerous. They will refine gold from the CPU and memory barns and put these things into the strong acid solution. The last step is to refine purity.
You can use strong acid decomposition, microorganisms extraction, zinc wire replacement can extract the gold in the old computer.
You can wash off the gold in the hard disk in the computer through some chemicals, and you can get gold to get less accumulated.
