  1. This invention relates to the refining and purification of karat gold to 98% purity. More particularly, it relates to a novel process, to a novel electrolyte and to a novel electrolytic cell apparatus and components for this process.

    Relatively raw gold is purified in two main ways. The cheaper first stage of purification is the Miller process which uses chlorine gas and reaches purification of 99.5%, and then there is the more expensive Wohlwill process which electrolyses gold to purities of 99.99%. London Good Delivery Bars - the main trading unit of bullion - are specified at 99.5% pure. Pure gold is 24 karats, or 99.999% pure. 100% pure gold is nearly impossible to refine.
