Abstract

In this study, a new process of pre-flotation decarbonization‑lead flotation‑zinc flotation was proposed to recover valuable metals from a lead‑zinc ore in Guizhou by beneficiation and to determine a reasonable and economic beneficiation process. The results of the study demonstrate that the novel process aids in the flotation of lead and zinc ores in two ways: (1) pre-decarbonization using MIBC (methyl isobutyl carbinol) and kerosene synergistically achieved the lowest loss of lead recovery of 1.94 % and zinc recovery of 1.14 % in the decarbonized product. (2) the successful separation and retrieval of lead and zinc metals were accomplished via a preferential flotation technique, using several combinations of reagents. This procedure yielded a lead recovery rate of 87.64 % and a zinc recovery rate of 94.09 %.

贵州典型含碳硫化铅锌矿预脱碳浮选回收研究
本研究提出了一种 "浮选前脱碳-铅浮选-锌浮选 "的新工艺,通过选矿从贵州的一种铅锌矿中回收有价金属,并确定了合理、经济的选矿工艺。研究结果表明,新工艺对铅锌矿的浮选有以下两方面的帮助:(1)使用 MIBC(甲基异丁基甲醇)和煤油协同进行预脱碳,脱碳产品中铅回收率损失最低,为 1.94%,锌回收率损失最低,为 1.14%。(2) 使用几种试剂组合,通过优先浮选技术成功分离和回收了铅锌金属。该方法的铅回收率为 87.64%,锌回收率为 94.09%。

期刊介绍: GEOCHEMISTRY was founded as Chemie der Erde 1914 in Jena, and, hence, is one of the oldest journals for geochemistry-related topics. GEOCHEMISTRY (formerly Chemie der Erde / Geochemistry) publishes original research papers, short communications, reviews of selected topics, and high-class invited review articles addressed at broad geosciences audience. Publications dealing with interdisciplinary questions are particularly welcome. Young scientists are especially encouraged to submit their work. Contributions will be published exclusively in English. The journal, through very personalized consultation and its worldwide distribution, offers entry into the world of international scientific communication, and promotes interdisciplinary discussion on chemical problems in a broad spectrum of geosciences. The following topics are covered by the expertise of the members of the editorial board (see below): -cosmochemistry, meteoritics- igneous, metamorphic, and sedimentary petrology- volcanology- low & high temperature geochemistry- experimental - theoretical - field related studies- mineralogy - crystallography- environmental geosciences- archaeometry
