摘要
通过运用分步浸出技术可在常温、常压条件下用硫酸浸出废镁砖中对火法冶炼影响很大的高熔点氧化镁等成分, 使金、银、铜等有价金属得到富集; 研究了在硫酸分步浸出条件下, 诸影响要素对氧化镁浸出的影响。该法简单实用, 效率高, MgO 的浸出率达到95% , 可直接用于工业化生产。
Abstract: Fractional sulfuric acid leaching of magnesium oxide that influence pyrometallurgical technology from waste magnesia brick at ambient temperature and pressure was conducted to comprehensively recover gold and silver, copper etc . The effects of various parameters on leaching were researched. The results showed that the fractional sulfuric acid leaching is simple and efficient. The leaching rate of magnesium oxide is 95%. It is proved that the system is easy to industrialize.
