Not at the same time. Sodium cyanide is a commonly used gold leaching agent that can form a complex with gold ions in gold ore to extract gold from the ore. Water glass is an auxiliary that can make sodium cyanide better. Penetrate into the ore, thereby improving the efficiency of gold leaching. Therefore, when leaching gold from ores with high mud content, only sodium cyanide is used as the gold leaching agent, and sodium cyanide and water glass are not used at the same time.
