一、情况介绍目前世界上开采的矿石有95％是经过选矿富集的,其余是直接熔炼。矿石和精矿的物质组成对熔炼的经济效果有很大影响,原料的金属含量越低,需要熔剂数量越大,电能和燃料消耗也越多。因此,从节约能源来看,选矿产品质量与冶炼过程是有密切关系的。随着选矿技术发展,精矿品位不断提高,不仅有助于降低冶炼产品或本、提高回收率、简化工艺过程
First, the situation introduced At present, 95% of the ore mined in the world is enriched by beneficiation, and the rest is direct smelting. The material composition of ores and concentrates has a significant impact on the economic performance of smelting. The lower the metal content of the feedstock, the greater the amount of flux required and the greater the electrical and fuel consumption. Therefore, from the energy conservation point of view, beneficiation product quality and smelting process are closely related. With the development of beneficiation technology, the continuous improvement of concentrate quality will not only help to reduce smelting products or increase recovery rate, but also simplify the process
