First, sort this out for yourself: There are two basic types of processes for gold, as follows.
1. Gold recovery processes.
2. Gold refining processes.
Get that clear in your mind before you try to understand anything else about this.
The recovery processes will remove your gold from the escrap material, and separate it from base metals.
The refining processes will purify the gold which you recover.
For recovery, there are a few different methods. The best method for recovery depends on what particular kind of escrap objects you are recovering the gold from.
For refining, there are only two basic methods which home refiners usually use.
The reasons for different methods, are cost of chemicals and accuracy of results. Using the wrong method on certain types of materials will cause more problems than they solve, resulting in loss of both time and money.
Thoroughly understanding these fundamentals, will allow you to build a good understanding of precious metals recovery and refining, and help avoid confusion in the future. These basic principles are the foundation of everything else on this site. Know them well.
Never use a refining process for recovery.
Never use a recovery process for refining.
Note: In your original question, you are asking for help in using a refining process for recovery. Not good. First get a good recovery method for a particular type of escrap. Then decide on which refining method to use.
