我国铬铁矿资源现状及可持续供应建议

Current Situation of Chromite Ore in China and Recommendation on its Sustainable Supply

介绍了世界铬铁矿资源的分布状况;分析了我国铬铁矿资源贫乏但需求量却不断增长,对外依存度已达到95%的国情以及目前铬铁矿选别多采用重选法所存在的局限性;提出了应加强浮选特别是新型浮选药剂的研究以及旨在保障我国铬铁矿资源可持续供应的相关建议。

This paper introduces the distribution of chromite in the world and reviews the phenomenon that the external dependence of chromite has reached 95% while the poor chromite resource in China is hard to meet the growing demand and the limitation in gravity separation of chromite at current.Then,the direction to strengthen the study on the flotation and especially some new flotation reagents is put forward,and the relative suggestions to ensure the sustainable supply of chromite resources are proposed.
