Hi, name's danny. I've spent the last few months reading about melting fine gold and seperating from black sands. Any advice is welcome. I have just recieved all the ingredients to make my own chapmans flux, (borax, manganese dioxide, soda ash and silica) i also have flourospar and lime 50/50 for a thinner.

Premium Gold Flux will treat other precious metals such as silver or copper as impurities and will tend to pull them out, leaving only your gold. If you prefer to save all precious metals in your concentrates, use our white Melting Flux, which has no manganese dioxide. You will then end up with an amalgam of your precious metals, meaning ...

There are fluxes that will clean up your gold and it is possible raise it up to 999. (I doubt 4 nines) A description from Hank Chapman's excellent book "How to smelt your gold and silver" This flux will take small amounts of copper and iron and silver and trap them in the flux. The secret sauce is Manganese dioxide. This is the formula from ...

Notes. This is available as a pure material or as a ground ore (pyrolusite). Thus while generically it is pure MnO2 the actual name-brand materials may only be 75% MnO2. During firing, half of the oxygen disassociates to produce MnO (with an associated LOI of 14%). MnO is a flux.It reacts with silica to produce violet colors in the absence of …
