铁矿资源回收与尾矿综合利用

结合山东省铁矿资源储量及铁矿石供需情况，分析了山东省省属以上铁矿山选矿生产工艺技术状况，总结了铁矿资源综合利用工作取得的成绩，指出山东省省属以上铁矿山仍存在选矿回收率低、设备落后等问题。为提高山东省铁矿资源回收及尾矿综合利用水平，应积极应用新工艺和新设备、做好磨前预选工作和尾矿再选工作、拓宽尾矿利用渠道等。

Recovery of Iron Ore Resource and Multipurpose Use of Tailings

Analyzes the technological processing conditions of the main iron ore dressing plants in Shandong Province and summarizes the achievement by comprehensive utilization of the iron ore resources under the present situation of supply and need for iron ore and regarding the reserves in the province. The problems, such as low recovery rate and backward in technique and equipment, even exist. Vigorous measures need to be adopted by using new technological process and equipment, adding pre-dressing before grinding and re-dressing of the tailings, and multipurpose using of the tailings.
