硼铁矿经磁选可分离为棚精矿和含硼铁精矿，硼精矿经活化焙烧可使B2O3活性大于90％，可直接用于碳碱法生产硼砂，含硼铁精矿可作添加剂改善烧结、球团的性能．硼精矿焙烧活化的主要原因是朋镁石问遂安石转化，矿物结构的变化引发的比表面积增大．烧结球团加入含硼铁精矿由于B2O3的作用使烧结球团中铁矿物晶粒长大，渣相量增大改善了固结条件，进而改善了烧结球团的性能．
Boron ore by magnetic separation can be separated into shed concentrate and boron-containing iron concentrate, boron concentrate activated by baking B2O3 activity can be greater than 90%, can be directly used for the production of borax carbon and alkali, boron-containing iron concentrate can be used Additives improve sintering, pellet properties. The main reason of calcination and activation of boron concentrates is the conversion of periclase into perovskite, which leads to the increase of specific surface area caused by the change of mineral structure. Addition of Sintered Pellets to Iron-Containing Boron Concentrates Due to the action of B2O3, the iron minerals in the pellets grow up and the amount of slag phase increases to improve the consolidation conditions, thereby improving the properties of the pellets.
