金红石在国民经济中用途广泛,我国每年需要大量进口。山西碾子沟金红石矿床位于五台西段草垛山分岭背斜南翼,金红石矿体赋存于碾子沟上段地层中,矿体产状与地层产状一致,矿体规模、产状和形态严格受岩体控制,矿化是吕梁期热液活动强烈影响的结果,使得金红石叠加富集。矿床含矿岩石主要为阳起透闪岩、绿泥透闪岩等。金红石呈半自形粒状结构,多分布于透闪石矿物之间。采用金红石(TiO2)边界品位1.0%、工业品位1.6%计算,共求得金红石(TiO2)资源/储量163万t,属于大型矿山。
Rutile is widely used in the national economy and China needs a large amount of imports each year. The Shanxi Nianzigou rutile deposit is located in the southern wing of the Wulingshan ridge of Wutai Mountain in the western part of Wutai. The rutile ore body exists in the upper cascade of Nianzigou. The ore body shape is consistent with that of the strata, and the size, shape and shape of the ore body Strictly controlled by the rock mass, mineralization is the result of strong influence of hydrothermal activity in Luliang Period, which makes the rutile superposed and enriched. The ore-bearing rocks in the orebodies are mainly Yang-tremolite and Chlorite-tremolite. Rutile semicircular granular structure, mostly distributed in the tremolite minerals. Using rutile (TiO2) 1.0% border grade and 1.6% industrial grade, a total of 1.63 million tons of rutile (TiO2) resources are obtained, belonging to a large-scale mine.
