Miller process the gold is removed and processed in the manner required for sale or use. The resulting gold is 99.95% pure, but of lower purity than gold produced by the other common refining method, the Wohlwill process, which produces gold to 99.999% purity. The Wohlwill process is commonly used for producing high-purity gold, such as in electronics work and the manufacture of some silicates, where exacting standards of purity are required. When highest purity gold is not required, refiners often utilize the Miller process due to its relative ease, quicker turnaround times, and because it does not tie up the large
Industrial processes Industrial processes Industrial processes are procedures involving chemical, physical, electrical or mechanical steps to aid in the manufacturing of an item or items, usually carried out on a very large scale. Industrial processes are the key components of heavy industry. These may be applied on their own, or as part of a larger process. The availability of electricity and its effect on materials gave rise to several processes for plating or separating metals. There are several physical processes for reshaping a material by cutting, folding, joining or polishing, developed on a large scale from workshop techniques. The physical shaping of
