海南贫铁矿石的金属矿物主要是赤铁矿,脉石矿物以石英为主,属难选氧化铁矿石。矿石结构复杂,铁矿物氧化程度很深。赤铁矿物嵌布粒度微细(下限均为0.003毫米),与石英致密共生,互相嵌布,相互浸染,有时石英呈核心嵌布在赤铁矿的鲕核中。柘榴子石和绿色矿物的比磁化系数与赤铁矿相近(图1)。多年来, The metal minerals of Hainan's poor iron ore are mainly hematite. The gangue minerals are mainly quartz, which is refractory to iron oxide ore. Complex ore structure, iron ore oxidation is very deep. Hematite cloth embedded fine grain size (the lower limit of 0.003 mm), and quartz dense symbiosis, mutual intercalation, mutual dip, and sometimes quartz was embedded in the center of hematite oolitic nuclei. The relative magnetization coefficients of garnet and green minerals are similar to those of hematite (Figure 1). Over the years,
