handmade jewelry supplies wholesale Hello
The first step, first throw the CPU into the nitrate solution (when the needle is dissolved in the pin or the contact, it needs to be soaked for 1-2 weeks)
The second step, filter the nitric acid solution used, in Add NACL (salt)
in the third step to the filtering solution. To prepare a small piece of zinc tablet and hydrochloric acid solution for silver chloride to be reduced into single -quality silver. It should be noted that the reaction will be performed in large quantities once the reaction starts. After adding zinc tablets and hydrochloric acid to the solution, zinc or the hydrogen generated by zinc or it can restore silver chloride at the same time. At the same time, silver chloride itself and light will be decomposed into silver single. It can be seen that a lot of black silver single quality has been precipitated.
The fourth step, filtering, this time we want the filter. For small particles, black powder silver is further melted. The oxygen-butane flame is used here. Of course, the "silver coins" completed by the melting are not even as pure as the conditions that are not as good as the workshop. It may be mixed with more valuable metals such as platinum, 铑, and 钯. If you want to improve the purity, you can only rely on better equipment and response conditions, processes, etc.
