一、鑛石的物理性质对选鑛过程的重要性我厂所处理的鑛石基本上是硫化铜鑛,鑛石的种类大体可分为两种:一种是斯卡隆鑛床鑛石,一种是含铜细脈鑛石。斯卡隆鑛床鑛石里的有用鑛物有斑铜鑛、辉铜鑛、黄铜鑛、黄铁鑛以及白钨鑛、辉钼鑛等;在含铜细脈鑛石里主要是黄铜鑛及黄铁鑛等。斯卡隆鑛床的鑛石组织情况一般是块状,即所谓富鑛,其组织比较粒大密集,硬度比较小,在5～6之间,而且容易被粉碎;另一种鑛石呈散点状存在,即所谓贫鑛,其组织比较细致;此外还有含铜细脈鑛石,硬度比较小,如果受矽化,其硬度亦
First, the physical properties of ore dressing process on the importance of mine processing I ore is basically copper sulfide ore, ore types can be broadly divided into two types: one is Skaron ore deposits, One is copper-bearing vein ore. The useful minerals in the mineral deposits of Skaron deposit are bentonite, chalcopyrite, chalcopyrite, pyrite, scheelite and molybdenite; in chalcopyrite vein, mainly chalcopyrite and pyrite Wait. The mineral structure of Skaron deposit is generally massive, the so-called rich ore, the organization of relatively large grain density, hardness is relatively small, between 5 to 6, and easily crushed; the other ore was scattered Point-like existence, the so-called lean ore, the organization more detailed; in addition to copper vein veins, hardness is relatively small, if by silicification, the hardness is also
