Concentrates发表评论(0)编辑词条

Iron ore concentrate is an output product from processed ores that have been milled (crush, grind, magnetic separation, +/- flotation) to separate deleterious elements and produce a higher quality product of 63% to 69% iron (Fe) compared to fines. It is sold to sinter and pellet plants and, due to its quality, usually commands a slight premium but is overall priced competitively with iron ore fines.

铁精粉
　　天然矿石（铁矿石）经过破碎、磨碎、选矿等加工处理成矿粉叫精矿粉。
　　精矿粉按照选矿方法的不同分为多种精矿粉，如磁选、浮选、重选等精矿粉。
　　铁矿石酸碱性确定:
　　根据矿石中（CaO+MgO）/(SiO2+Al2O3)的比值，可以确定矿石的酸碱性：
　　（CaO+MgO）/(SiO2+Al2O3)值 ‖ 矿石性质
　　<0.5 ‖ 酸性矿石
　　0.5-0.8 ‖ 半自熔矿石
　　0.8-1.2 ‖ 自熔性矿石
　　> 1.2 ‖ 碱性矿石
