亨德森(Henderson)钼矿是美国最近新建的一个现代化大型采选企业。矿山位于科罗拉多州丹佛城以西80公里、海拔3140米的山区,1967年开始基建,1976年8月投产,1977年产量逐渐增至9000(吨/日),予计1979年底达到设计能力,日产27000吨。矿体象一个倒置的盆状,赋存在流纹斑岩中(图1),平面似椭圆,南北长900米,东西宽660米,厚120～240米,顶部复盖层高约520～1120米。按最低工业品位0.2％进行计算,矿石储量共约2.75亿吨,平均含MoS_20.49％,主要矿物为辉钼矿。
Henderson molybdenum mine is the United States recently built a large modern mining company. The mine is located 80km west of Denver in Colorado and 3140m above sea level in the mountains. It started construction in 1967 and commenced production in August 1976. Its output gradually increased to 9,000 (tonnes / day) in 1977 and is expected to reach design capacity by the end of 1979 with a production capacity of 27,000 Ton. The ore body resembles an inverted basin, with the presence of rhyolite porphyry (Figure 1). The plane resembles an ellipse with a length of 900 meters from north to south and a width of 660 meters from east to west with a thickness of 120 to 240 meters. The top cover is about 520 to 1120 Meter. According to the calculation of the lowest industrial grade of 0.2%, the ore reserves are about 275 million tons on average, containing MoS_20.49%. The main minerals are molybdenite.
