Miller process Miller process The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.95%). It was invented by Francis Bowyer Miller ( patented 1867). This chemical process involves blowing a stream of pure chlorine gas over and through a crucible filled with molten, but impure, gold. This process purifies the gold because nearly all other elements will form chlorides before gold does, and they can then be removed as salts that are insoluble in the molten metal. When all impurities have been removed from the gold (observable by a change in flame color)
Industrial big data general-purpose big data analytics might not work well for industrial data. Industrial big data requires deeper domain knowledge, clear definitions of analytical system functions, and the right timing of delivering extracted insights to the right personnel to support wiser decision making. As data from automated industrial equipment are being generated at an extraordinary speed and volume, the infrastructure of storing and managing these data becomes the first challenge any industry will face. Different from the tradition business intelligence which mostly focuses on internal structured data and processes that information in regularly occurring cycles, "Industrial Big Data” analytical system requires near
