Miller process amount of gold in the form of chloroauric acid which the Wohlwill process permanently requires for the electrolyte. 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
Refine S2 electric motor producing 116 hp and 270 Nm of torque. The iEV7S comes with a 39 kWh battery, and the range of the iEV7S is 280 kilometers. The same platform later spawned the SOL E20X from SOL, the EV joint venture between Volkswagen and JAC, with only a minor restyling for the front and rear DRGs in an attempt to recreate SEAT's styling on the iEV7S. Refine S2 The Refine S2 is a subcompact CUV produced by JAC Motors under the Refine sub-brand. It was positioned between the Refine S2 Mini and the Refine S3 compact CUV. The Refine S2
