Gold parting in 1860's Australia. It is able to refine gold up to 99.5% purity. The process involves blowing a stream of chlorine gas over and through a crucible filled with molten impure gold. Impurities in the gold form chlorides before the gold does and these insoluble salts are removed from the melt by skimming the surface. Invented by Emil Wohlwill in 1874, this produces the highest purity gold (99.999%). It is an electrolytic process using pure gold for the cathode (or titanium as a starter cathode) and chloroauric acid (gold chloride-hydrochloric acid) as the electrolyte; this is made by dissolving gold
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
