一前言通常所称的氧化铜矿系指范围很广的多种矿石。所谓的绿色铜矿,其代表矿物即为最普通产出的孔雀石和硅孔雀石。虽然象孔雀石、兰铜矿这类的碳酸盐铜矿物容易硫化而且用黄药捕收剂也能浮选,但硅孔雀石这样的硅酸盐铜矿物的浮选尚未工业化。另外,用脂肪酸也可浮选碳酸盐铜矿物,但如果脉石中含有方解石时,据说无论采用什么方法,也是不能使两者分离。本研究是对含有孔雀石、硅孔雀石和方解石的绿色氧化铜矿石,首先考察了试验用的试样在矿物学上的性质,然后进行浮选试验,查明了关于矿石性质和浮选成绩的相互关系,其研究结果的要点叙述如下。
A preface Commonly called “copper oxide” means a wide variety of ores. The so-called green copper mine, the representative mineral is the most common output of malachite and silicon malachite. Although carbonate copper minerals such as malachite and blue copper are readily sulfidated and can be flotated with xanthate collectors, flotation of silicate copper minerals such as chrysocolla has not yet been commercialized. In addition, fatty acid also flotates carbonate copper minerals, but if the gangue contains calcite, it is said that no matter what method is used, it is not possible to separate the two. In this study, a green copper oxide ore containing malachite, silicon malachite and calcite was first investigated for its mineralogical properties and then for flotation tests to ascertain the nature of the ore and flotation results The main points of the research results are described below.
