摘　　要：盐湖作为重要自然资源,蕴含着丰富的无机盐资源,受到全球广泛关注。阐述了近年来国内外对盐湖中钾、镁、锂和硼等盐产品的开发利用现状,系统梳理了浮选法提钾、电解法产镁、沉淀法收锂、酸化法析硼等主流提取工艺,还指出了盐湖产业开发中面临的主要问题,不合理的开采方法导致尾矿堆积和资源品位下降。针对未来盐湖资源的综合利用前景,建议构建智能化生产体系,集成清洁工艺与资源循环技术,重点突破低品位盐湖元素提取设备创新,推动盐湖资源向高效化、低碳化、全元素联产方向转型升级,实现生态保护与资源价值最大化协同发展。Salt lakes,as critical natural repositories of inorganic salt resources,have attracted global attention due to their strategic mineral reserves.This paper systematically reviews recent advances in exploiting potassium,magnesium,lithium,and boron salt from salt lakes,detailing mainstream extraction methodologies:flotation for potassium,electrolysis for magnesium,precipitation for lithium,and acid leaching for boron.And it further identifies key challenges in salt lake industrial development,particularly suboptimal extraction methods that induce tailings accumulation and a decline in resource quality.To address the future comprehensive utilization of salt lake resources,it is suggested to build an intelligent production system that integrates environmentally benign processes and resource recycling technologies,and focuses on innovative equipment for the extraction of low-grade salt lake elements.This will promote the transition toward high-efficiency,low-carbon,and multi-element co-production paradigms.Such integrated approaches help achieve coordinated development of ecological preservation and resource value maximization in salt lake ecosystems.
