金属钴被广泛用于电池的正极材料，例如镍钴锰酸锂电池即三元锂电池。钴的加入可以提高三元锂电池的能量密度、热稳定性以及充放电效率等。随着新能源汽车的发展和国家能源结构的调整，未来对钴的需求将会越来越大。然而，钴保有资源量的严重不足造成了钴价的疯狂上涨，也制约着电池产业对金属钴的使用。
芦子园超大型Pb-Zn-Fe多金属矿床是保山地块上系列同类矿床的典型代表，矿体呈似层状顺层产出，含矿围岩以矽卡岩为主；地质、物探、化探、遥感等综合推断深部存在隐伏岩体，但已知矿床内未见到隐伏岩体且未获得直接的成矿年龄等，矿床成因一直存在较大分歧。矿床深部发现蔷薇辉石与Fe、Pb、Zn、Cu矿化具密切的共伴生关系以及往深部蔷薇辉石含量增加、颗粒增大等特征，具有重要的矿床成因指示意义。本文对蔷薇辉石的...
晶体化学中，阳离子通常与阴离子相键合，至今尚未发现阳离子Fe2+与As3+之间形成键合的矿物或化合物。南岭石是我国70年代发现的新矿物，其晶体结构至今尚未得到测定。
