某地含磷磁-赤铁矿是属于高温热液矿床。这次研究的原矿石是产于该矿床的氧化带。矿石中的主要铁矿物以磁铁矿及赤铁矿为主,其次是褐铁矿及假像赤铁矿。矿石中的含磷矿物主要是磷灰石。脉石矿物有:阳起石、绿泥石、石英、长石及粘土等。磁铁矿大部分呈他形晶粒集合体产出,嵌布粒度不均,最粗1.6毫米,最细0.08毫米,一般为0.4～0.1毫米,在磁铁矿边沿及节理处常有赤铁矿伴生;赤铁矿一般是以不规则粒状集合体嵌布于脉石中,有的赤铁矿与褐铁矿连生。赤铁矿粒度一般在0.09～0.2毫米,最粗者达1.6毫米;褐铁矿及假像赤铁矿粒度一般在0.08～0.1毫米,磷灰石大部分呈自形晶半自形晶粒状集合
A certain area of magnetite-hematite belongs to high-temperature hydrothermal deposit. The raw ore for this study is the oxidation zone produced in this deposit. The main iron ore minerals are mainly magnetite and hematite, followed by limonite and artifact hematite. The phosphorus minerals in the ore are mainly apatite. Gangue minerals are: Yang stone, chlorite, quartz, feldspar and clay. Most of the magnetite was he-shaped grain aggregate output, uneven distribution of cloth, the most coarse 1.6 mm, the smallest 0.08 mm, usually 0.4 to 0.1 mm, often in the magnetite edge and joint hematite Ore associated with; hematite generally irregular aggregates embedded in the gangue, and some hematite and limonite associated. The hematite size is generally 0.09 ~ 0.2 mm, the most rough reach 1.6 mm; limonite and artifact hematite size is generally 0.08 ~ 0.1 mm, most of apatite was self-shaped crystalline grain set
