The melting process creates very large ascast grains that result in poor workability, so arccast ingots must be extruded at high temperatures to refine their grain size before further processing. This combination of factors mean the arccast process produces a narrower range of mill product sizes and geometries than the presssinter process.

How to refine gold

How to refine gold

The resulting product is a muddy substance that is almost pure gold (% or 24K). This muddy substance is dried until it is a powdered residue and then heated with a torch or other source of heat to melt the gold powder into useable gold. The acids used for this process are Nitric acid and Hydrochloric acid. Read more common gold questions.
