苏北地区人工金红石砂矿特征及开发利用的可行性

摘要

During the field work, the author found that there are a lot of artificial rutile placer in Northern Jiangsu area of China, through the systematic investigation, sampling, microscopic identification, chemical analysis and comprehensive research,considers that it is tailings by discharged in process of dressing almandine from eclogite.Higher ore grade, coarser rutiles size,vast majority of them dissociated from other minerals, adequate reserve resources and good feasibility of development,make the placer into important economic value ones that has become new genesis and industrial type of rutile ore deposit. The development of the artificial rutile placer is suggested to avoid the loss of precious resources.%提 要 笔者在野外工作期间,发现在中国江苏北部地区存在大量人工金红石砂矿,经系统调查、采样、镜下鉴定、化学分析及综合研究,认为其实质为采选榴辉岩中的铁铝榴石排放掉的尾矿,金红石品位高、粒度粗、绝大多数已离解,后备资源充足,开发可行性良好,具有重要经济价值,已成为金红石矿床新的成因和工业类型,建议开发利用,以避免宝贵资源流失.
