利用选铁尾矿及铁矿副产品制备土壤调理剂关键技术及应用研究

Key technology of the preparation of soil conditioning agent from iron tailings and iron ore by-products and its application research

通过对选铁尾矿及其副产品进行矿物学分析,在调研当前土壤调理和修复技术产品的基础上,进行矿物组成复配和活化试验研究,成功制得土壤调理剂产品。田间作物效应试验结果证明了土壤调理剂的改酸增产提质效应,为土壤调理剂配方优化、功能多样化和剂型系列化研发生产提供了依据。

Through mineralogical analysis of iron dressing tailings and its by-products,based on the investigation of current soil conditioning and remediation technology products,the mineral composition compound and activation test research were carried out,and the soil conditioning agent was successfully developed.The field crop effect test results proved the acid modification,production and quality improvement effects of the soil conditioning agent,which provided a basis for the optimization of the formulation of the soil conditioning agent,the diversification of functions and the serialization of products.
