1·The domestic ores are fine magnetite concentrate, and the imported ores mainly are hematite sinter fines.

国产铁精矿是细粒度的磁选精矿，进口铁矿则以粉状赤铁矿为主。

2·A desulfurization research on the magnetite concentrate with a sulfur content over 0.4% was conducted by flotation column.

采用浮选柱对某铁矿选矿厂生产的含硫量超过0.4%的磁铁矿精矿进行了脱硫试验研究。

3·Then S content in concentrate can be lowered to 0.26% by reverse flotation desulphurization flow-sheet, with high-grade magnetite concentrate finally achieved.

该铁精矿通过反浮选降硫使含硫降至0.26%，最终获得优质的钒钛磁铁矿精矿。

4·Since magnetite concentrate in AnSteel Groupe mining corporate do not fully meet the consumption requirements of pellets, hematite and magnetite concentrate are mixed to prepare pellets.

针对鞍钢集团矿业公司磁铁矿精矿不能完全满足球团矿的用量要求，采用赤铁矿与磁铁矿的精矿混合配制球团。
