When used for refining material that doesnt contain PGMs, the inquartation and parting process is capable of producing gold of up to 99.99 percent purity. The process is particularly suited for treatment of low karat gold scrap, since large additions of copper or silver are unnecessary to achieve the desired 25 percent or less gold content.

Gold Inquartation Process Mineral Processing Metallurgy

This is called “inquartation.” The resulting bead is cleaned, flattened by a hammer, and dropped into nitric acid. Even if the gold is less than one-fourth the weight of the bead, additional silver is sometimes required. When the amount of gold is small, it is convenient to use a large proportion of silver in parting.
