苏北榴辉岩型金红石资源的综合利用

THE COMPREHENSIVE UTILIZATION OF ECLOGITE-RUTILE RESOURCES IN NORTH JIANGSU

金红石和铁铝榴石是中国榴辉岩型金红石资源中可供综合利用的两种重要矿物组分。目前苏北地区众多的选矿企业针对此类型资源的开发,仅选铁铝石榴石,导致金红石在废弃的尾矿中高度富集。金红石在尾矿中的含量,一般在3.16%～7.59%之间,最高的接近8%,平均5.24%。尾矿实质上已成为品位极高的人工金红石砂矿。综合利用,不但可大幅度提高企业的经济效益,更重要的是可避免国家宝贵资源的浪费。

Rutile and almandine are the two important comprehensive utilizable mineral component in China eclogite-rutile resources. At recent, most ore dressing corporations in north of Jiangsu province beneficiate the almandite only to cause the high grade of rutiles in the tailings. The content of the rutiles in the tailing is from 3.16% to 7.59%, with the highest at nearly 8%, and the average value is 5.24%.To comprehensive utilize the tailing which had became the manual work rutile placers with high grade could not only increase the economic benefit by big percentages, but also avoid wasting of national valuable resources.
