Beschreibung
Zusammenfassung:	The invention relates to a gold/silver ore alkaline leaching method. During alkaline leaching, calcined soda (sodium carbonate) serves as a leaching agent. After the technology is adopted in the gold smelting flow, the grade of cyanidation slag is obviously reduced, the leaching rate of gold is improved, production cost is correspondingly reduced, and production benefits are improved. Accordingly, the technology will have the important application purpose in the wet metallurgy industry. 本发明涉及种金/银矿的碱浸方法。碱浸时采用纯碱(碳酸钠)做浸出剂。该工艺技术在黄金冶炼流程中采用后明显的降低了氰化尾渣的品位，提高金的浸出率，相应的降低了生产成本，提高了生产效益。因此该工艺技术在湿法冶金工业中应会有重要的应用前途。
