一、概述本文试图将目前在工业生产中作为“能量消耗者”的硫化铜精矿的不同熔炼方法作一比较,尽可能说明为什么各种方法的能耗不一,指出节省能量的方法的特征。在五种主要金属铁、铝、铜、铅、锌中,就单位体积来说,铜是耗能量最多的金属。就单位重量来说,铜居第二位,仅次于铝。大部分铜矿石的品位都很低,因而每回收一个单位的金属时,采矿和选矿都要消耗大量能量,生产精铜所需能量约有55％消耗于这些部门。与原生铜工业的这些受矿石限制的部门相比,从精矿到制取阳极铜的单位能耗(目前平均)约为精铜生产总能耗的30％,看来能够使用保护的办法及重新设计熔炼方法而使之大幅度降低。如果熔炼所用的能量确实大幅度减少,就可补偿采矿和选矿面临的极为可能的能耗增加。
I. INTRODUCTION This article attempts to compare different smelting methods for copper sulfide concentrates currently used in industrial production as an “energy consumer” and try to explain as much as possible why different methods consume more energy and indicate the characteristics of the energy-saving method . Among the five major metals, iron, aluminum, copper, lead, and zinc, copper is the most energy-consuming metal per unit volume. In terms of unit weight, copper ranks second, behind only aluminum. Most copper ores have very low grade, so each recovery of one unit of metal consumes a great deal of energy for both mining and beneficiation, and about 55% of the energy required to produce refined copper is consumed in these sectors. The unit energy consumption (currently average) from concentrates to anode copper production is about 30% of the total energy consumption of refined copper production compared to the ore-limited sectors of the native copper industry, and it appears that protection can be used Redesign the smelting method to reduce it drastically. If the amount of energy used for smelting is indeed substantially reduced, it is possible to compensate for the most likely increase in energy consumption in mining and dressing.
