Study on flotation recovery of typical carbon-bearing lead-zinc sulphide ore in Guizhou with pre-decarbonization
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 %.
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
