Mill grade of ore, recoveries and tailing grade are very correlative during dressing processes.
在选矿过程中，矿石的原矿品位、回收率、尾矿品位三者是密切相关的。
The tailing of Dahongshan iron Concentrator has a high iron grade of 27.92%, representing a serious metal loss.
大红山铁矿选矿厂尾矿铁品位较高，为27.92%，金属损失严重。
The cement can meet the standard of Portland cement of 42.5r and 32.5r grade in strengths when added to 20% and 30% lead-zinc tailing powder respectively.
加入20%尾矿粉后水泥可满足普通水泥42.5R的强度要求，掺加30%尾矿粉后水泥可达到普通水泥32.5 R的强度要求。
Further reduction of the tailing iron grade for comprehensive recovery of resource is imperative.
进一步降低尾矿铁品位，综合回收利用资源势在必行。
