湖南省七宝山硫铁矿为—铜铅锌多金属有色矿山。由于矿石类型多,性质复杂,其难选程度比日本黑矿还大。设计中已考虑在破碎筛分后设混矿栈,作者认为仍有必要在粗碎前增设堆矿坪,以保证入选原矿性质的相对稳定,从根本上改变来什么矿处理什么矿的被动局面,提高工艺指标。 一、矿石性质决定了多次混矿的必要性 1.老虎口矿段矿石由于热液的多次迭加成矿,矿体内矿石金属含量不稳定和矿石结构的差异,导致矿石类型极为复杂。自然类
Qibao Mountain in Hunan Province for the pyrite - copper, lead, zinc and nonferrous metal mines. Due to the ore type and complex nature, its refractory degree is still larger than that of black ore in Japan. In the design, it has been considered to set the mixed ore stack after crushing and screening, and the author thinks it is still necessary to add a heap and pits before the coarse crushing so as to ensure the relative stability of the selected ore and fundamentally change the passive situation , Improve process indicators. First, the nature of the ore determines the necessity of multiple mixed ore 1 tiger mouth ore ore due to hydrothermal multiple superposition of mineralization, ore body ore metal content is unstable and the differences in ore structure, resulting in extremely complicated ore type.
