摘　　要：用硝酸分解磷矿制备硝酸磷肥和工业级碳酸钙、可高效地开发利用贵州丰富的中低品位磷矿资源;结合贵州煤炭资源优势可形成产业集群,在解决了磷化工对硫资源的过度依赖问題时,也避免了大量磷石膏的排放对环境造成的影响;对提高磷矿资源利用率生产高附加值产品、促进企业清洁生产、发展循环经济、实现可持续发展具有重要战略意义。It could develop and use abundant medium and low grade phosphorite resources in Guizhou that did prepare nitro - phosphate fertilizer and side - produced industrial calcium carbonate by nitric acid solving phosphor- ite. It could form industrial cluster combining Guizhou＇ s coal resources, not only resolving the problem as over - dependency of phosphorus chemical industry to sulfur resources, but also avoiding the influence from a large amount of phosphorus gypsum to the environment. It has important strategic significance to improve the utilization rate of phosphorite resources, producing products with high added value, to promote cleaner production in enterprises, to develop circular economy, to realize sustainable development.
