Gold or even silver can be cleaned up a little bit (slightly) in a melt with flux, but in reality the improvement is only minor basically, and even if you tried it with the placer gold you still would most likely not improve the gold to make it workable enough to make jewelry out of the impure gold. The gold needs refined.
Direct smelt with sulfides and iron rod/chunks in basic flux will reduce all sulfides to iron sulfide, which is relatively soluble in basic slag. Roasting of sulfides is also an option before smelting (if you cannot figure out anything to flux the sulfide junk out without matte). You need relatively high temperatures to liquify certain mixtures.
Stock flux may consist of a basic flux ingredients like: Borax, sodium carbonate (soda ash, or washing soda), quartz sand or crushed ground glass. Then they may add as needed: A tiny bit of fluorspar (or fluorite ore), to help viscosity. A metal collector, lead oxide, copper silver... Flour, corn meal, or other carbon source as a reducer.

My base recipe was: 40% fused borax, 25% potassium nitrate, 20% soda ash, 15% silica. I chose this as a starting point because it has been successful with other local sulfide ore that I've smelted. I tried other formulations, including variations of the above as well as the classic Chapman's Flux. S SquintNSquirt 2 years ago Like
Fluxes are special blends of typically solid, inorganic compounds designed for cleaning, degassing, grain refining, and/or chemistry modification of molten aluminum alloys and other purposes. A flux recipe varies depending on its purpose and other process variables, such as alloy and temperature.
Here is how. [adjust amount of total flux to your needs] use a tablespoon for measuring flux mix instead of pounds for each part. 1, anhydrous Borax, 5 parts. [regular Borax from the supermarket will do the same] 2, #70 silica sand, 40 parts. [get it at any home depot] 3, soda ash, 10 parts. 4, sodium nitrate, 20 parts [oxidizer].
Biringuccio and Theophilus all discuss it as a flux to aid the melting of precious metals in contexts other than silver smelting. Agricola mentions borax (p. 247) for the assay of lead minerals.9 Biringuccio included it in his general list of fluxes (p. 143). Considering that borax was a well-known flux in period, I think
