Wohlwill process and electricity travels through the electrolyte of chloroauric acid. Gold and other metals are dissolved at the anode, and pure gold (coming through the chloroauric acid by ion transfer) is plated onto the gold cathode. When the anode is dissolved, the cathode is removed and melted or otherwise processed in the manner required for sale or use. The resulting gold is 99.999% pure, and of higher purity than gold produced by the other common refining method, the Miller process, which produces gold of 99.95% purity. For industrial gold production the Wohlwill process is necessary for highest purity gold applications. When
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
