摘要铁矿石是钢铁工业最重要的原料之一，为了科学、合理、有效的利用铁矿石，矿山和钢铁企业需要了解所有铁矿石的品位和质量。矿山、选矿厂等生产企业，需要确定自己所生产和洗选加工的铁矿石的品味和质量，以确定矿区经济价值，并指导铁矿石的生产；钢铁企业需要了解有关进厂铁矿石的品位情况，以指导钢铁生产，并对其产品进行质量控制，要正确评价勘测区的铁矿石品位、基本特征及其变化规律；铁矿石的供需双方需要对铁矿石进行正确检验以便进行贸易结算。铜的含量也是铁矿石重要品位之一，它直接导致冶炼金属的强度。本论文主要介绍铁矿石铜含量的测定的两种方法，一种是化学分析：双环乙酮草酰二腙光度法；另一种是仪器分析法，原子吸收分光光度法；最后根据本化验室的实际情况以及多次试验进行测定已经被我们所采用的化学方法测铜法，本试验所造成的误差可以达到我们的要求。关键词：铜，双环乙酮草酰二腙光度法，原子吸收分光光度法，铁矿石ABSTRACTthe Iron ore is the most important raw material in steel industry, steel enterprises need to evaluate the quality of the iron ore for scientific, reasonable and effective utilization of iron ore mines. Steel enterprises need to know about the grade of iron ore into the factory to guide steel production, control the product quality, and correctly evaluate the grade, the basic characteristics of iron ore; We describle two methods for determination of iron ore copper content in this paper, one is chemical analysis: dicyclohexanonexalyl dihyfrazone (BCO) spectrophotometric method; Another is the instrumental analysis, atomic absorbent spectrophotometry. And we adopt the chemical method according to the actual requirement. Keywords: copper, BOC spectrophotometric method, atomic absorption spectrophotometry , iron ore目 录前言-------------------------------------------------------------------------------------------------11. 吸光光度法-------------------------------------------------------------------------------------31.1 紫外与可见光吸收光谱的形成-----------------------...
