波兰鲁德纳铜选矿厂(Rudna)设计年处理1500万吨矿石。矿石为沉积型,分三种类型:一是砂岩型;二是沥青页岩型,三是白云石型。主要金属矿物为辉铜矿,其次是斑铜矿和黄铜矿。原规定,选矿由几个年各处理2.50万吨的系统组成。第一期工程(2.5百万吨/年)建成时修改了设计,故第二期建年处理7.5百万吨的系统。矿石在地下破碎至-250毫米,送到地面,虽然矿石的矿物组成和物理性质不
The Rudna copper concentrator in Poland is designed to process 15 million tonnes of ore per year. Ore sedimentary type, divided into three types: one sandstone type; the second is bituminous shale type, the third is dolomite type. The major metallogenic minerals are chalcocite, followed by adatomite and chalcopyrite. The original provisions, beneficiation from several years to deal with the system of 250,000 tons. The first phase of the project (2.5 million tonnes / year) was designed with modifications. The second phase of the project will handle 7.5 million tonnes of systems. The ore is crushed underground to -250 mm and sent to the ground, although the mineral composition and physical properties of the ore are not
