钴湿法冶炼中间品的表征及属性鉴别

扫码查看
近年来,由于新能源技术的广泛应用,钴的进口量迅猛增加,一些以钴冶炼中间品名义申报的固体废物也充斥了进来.由于钴的冶炼中间品没有明显的物相结构特征,传统的感官检验和单一的X射线衍射(XRD)分析,无法对其准确鉴别.本文采用基于X射线衍射、X射线荧光光谱(XRF)、超景深显微镜、热重分析以及扫描电镜(SEM)等技术相结合,针对无明显衍射峰的两例钴湿法冶炼中间品进行属性鉴别.综合表征的结果表明,两例含钴物料为氢氧化钴,属钴湿法冶炼中间品.确定样品来源,为海关监管和资源利用提供了科学依据.
Characterization and attribute identification of intermediate products in cobalt hydrometallurgy
The import volume of cobalt increases rapidly in recent years due to the wide application of new energy technology.Some solid wastes are also declared in the name of cobalt smelting intermediates.Since the smelting intermediates of cobalt have no obvious phase structure characteristics,they cannot be accu-rately identified by the conventional sensory inspection and single X-ray diffraction(XRD).In this paper,XRD was combined with X-ray fluorescence spectrometry(XRF),super depth-of-field microscope,thermo-gravimetric analysis and scanning electron microscope(SEM)for the attribute identification of two interme-diates in hydrometallurgy of cobalt which had no obvious diffraction peaks.The comprehensive character-ization results showed that two cobalt-containing materials were cobalt hydroxide,which belonged to the intermediate products in hydrometallurgy of cobalt.The confirmation of sample source provided scientific basis for the customs supervision and resource utilization.
