一般情况一般从铜铅电解精炼的阳极泥、砂金、以及合质金金银为原料回收金的过程中,在最后精炼电金阶段,金阳极板除金外其余大部分是银等不纯物。银在金电解进行时成力氯化银密集在阳极上,阳极呈不働态致使一般的直流电解方法不能进行。因此采用脈流方法来解决这种操作困难,但脈流方法也要求阳极板的品位侭量提高,一般应在90%以上。由于金电解的原料(银电解阳极泥)的组成为Au50-60%,Ag 40-50%(当银阳极在Ag 90~92%、
In general, from the electrolytic refining of copper and lead anode mud, placer gold, as well as gold and silver alloy gold as the raw material recovery process, in the final phase of refining gold, gold and gold plates in addition to the rest of the rest are silver and other impurities . Silver in the progress of electrolysis of silver chloride concentration in the anode, the anode was unsmoothed so that the general method of DC electrolysis can not be carried out. Therefore, the use of pulse-flow method to solve this operational difficulties, but the pulse flow method also requires the positive plate to improve the level of quality, generally should be 90%. Since the composition of the gold electrolysis raw material (silver electrolytic anode slime) is Au 50-60%, Ag 40-50% (when the silver anode is 90-92% of Ag,
