Borax for fluxes: During smelting, borates reduce melting temperature and viscosity, dissolve metallic oxide impurities at a relatively low temperature, lowering energy costs Refinement and impurity removal: Any oxides, impurities, or siliceous material will be subject to borates' high solvent action when used as a refining flux Electroplating: By controlling pH, boric acid …

White quartz sand works well for a source of silica, ground glass was basically sand at one time, and will also work as a source of SiO2, the glass can be a bit cleaner and can give a little less trouble capturing values as the crushed quartz or silica sand will, I assume this is because the glass is cleaner, or has been refined by fire previously.

Then the excess mercury is burned off, I think the ratio of precious metal to mercury is something like 1/5. Then the mercury is burned off when the gold is melted. The borax was only used after the gold had been extracted. At best the borax was used to refine impurities, not extracting the gold.
