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 materials by forming their liquid form using a mould. Many materials exist in an impure form, purification, or separation provides a usable product. Early production of iron was from meteorites, or as a by-product of copper refining. The nature of an organic molecule means it can be transformed at the molecular level to create a range of products. Organized by product: A list by process: 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
