根据矿床成因,矿物成份以及矿石結構等,錫石——硫化矿床可以进一步区分为下列几个类型: (一)硅嘎岩类型: (二)电气石——硫化物类型; (三)綠泥石——硫化物类型; (四)方铅矿——閃鋅矿类型。上列各类型矿石的共同特点是富含鉄的硫化物及鉄质矿物,例如鉄的鋁硅酸盐、磁鉄矿等。矿石中一般均含有大量磁黄鉄矿及少量黄铁矿、白鉄矿、黄铜矿、閃鋅矿,以及数量极少的輝钼矿。非金屬矿物主 According to the genesis of the deposit, mineral composition and structure of the ore, the cassiterite-sulphide ore deposit can be further divided into the following types: (1) types of albugas: (II) tourmaline-sulphide type; Stone-Sulfide type; (IV) Galena-sphalerite type. The common features of the above types of ores are 富-rich sulfides and ores, such as 铝 aluminosilicates, magnesia and the like. The ore generally contains a large amount of pyrrhotite and a small amount of pyrite, white ore, chalcopyrite, sphalerite, and a very small number of molybdenite. Non-metallic mineral Lord
