The reaction of carbonate & silver chloride under high temperature produces silvercarbonate, which is decomposed into argent, thus reclaiming argent from the waste liquid.
利用碳酸盐与氯化银在高温下作用生成碳酸银，碳酸银分解得到金属银，从而提取回收含银废液中的金属银。

The leached out residue is reduced by sodium carbonate, then the gdd-silver alloy is decomposed by nitric acid, and finally zinc powder is used to replace silver.
