司家营铁矿是我国大型铁矿山之一,矿体为鞍山式沉积变质磁铁石英岩,上部由浅到深受到不同程度的氧化作用,至-185m水平氧化界线基本结束而过渡到原生矿。工艺矿物学研究表明,氧化带中有用矿物主要是假象赤铁矿和磁铁矿,磁铁矿多呈半假象赤铁矿形式产
Sijiaying iron ore mine is one of the large iron mines in our country. The ore body is Anshan-type sedimentary metamorphic magnetite quartzite. The upper part is oxidized to different degrees from shallow to deep and reaches the level of -185m. . Process mineralogy studies have shown that the oxidation of useful minerals are mainly artifacts hematite and magnetite, magnetite mostly semi-artificial hematite form
