If you are refining filigree or jewelry, shotting is not necessary. 2. Pour the shot into one or more Pyrex or plastic containers. For every ounce of scrap gold you are going to refine you will need a capacity of 300 milliliter. So, for example, if you are refining 10 ounces, you need a 3,000 milliliter (3 liter or 3 quart) container. 3. Add
Processing, smelting and refining gold. From ore to dor#233; . Cyanidation. More gold is recovered by cyanidation than by any other process.

*Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony or bismuth, present in the ore.
Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam).Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as color) embedded in rock minerals..
