(1) For the first time, a positive flotation desilication industrial trial of low-grade diaspore-type bauxite in Shanxi Province was completed, and a “bauxite stage grinding—a new technology for enhanced collection and coarse grain selection†was formed. . The industrial test runs stably. When the ratio of aluminum to silicon in raw ore is 4.4-5.1, the technical indexes of concentrate yield 72.73-77.78%, aluminum-silicon ratio 9.70-10.53, and alumina recovery 81.07-85.42% are obtained.
(2) Stage grinding is used to increase the selective disintegration, so that the better monomers of low-grade bauxite are dissociated, and the grain-size distribution characteristics of the grinding products are improved, and the silicate minerals are reduced. Facilitate the improvement of flotation indicators and improve the product's settlement filtration performance;
(3) The developed hybrid high-efficiency collectors have a strong collection effect on diaspore, and improve the flotation separation selectivity of alumina-silica minerals and the recovery rate of the target minerals;
(4) The coarse-grained rapid-selection process significantly optimized the particle size distribution of the concentrate, improved the flotation index, shortened the process, and reduced the consumption;
(5) Through the study of tailing settlement and dry storage technology, the appropriate flocculants and dehydrating agents were selected to provide technical basis for bauxite ore dressing production, tailing settlement and dry storage. The process solves the technical bottleneck of the use of ore backwater and realizes the full utilization of backwater.
Experts believe that the project provides low-grade diaspore-type bauxite for Shanxi A/S4-5, which uses the Bayer process to produce alumina and provides economical and feasible beneficiation technology. The overall technology has reached the international advanced level. The results of the project laid the foundation for the beneficiation production of low-grade bauxite in Shanxi and has extensive application value.
Shanxi Low Grade Bauxite Stage Grinding - Enhanced Capture and Flotation New Technology Project Appraisal
Recently, the China Nonferrous Metals Industry Association organized and organized the “Low-grade bauxite stage grinding in Shanxi Province†jointly completed by China Aluminum Corporation Zhengzhou Research Institute, Shanxi Branch, Zhongzhou Branch, and Central South University in Zhengzhou. "Flotation of new technology" project appraisal meeting. The experts attending the meeting carefully listened to the report of the research team and reviewed the appraisal data provided by the project team. After careful discussion, experts believed that the project took low-grade bauxite from Shanxi as the research object, systematically carried out laboratory and industrial test research, and achieved The expected goal has the following innovations:
Grinding machine refers to a grinding machine that grinds the workpiece surface with a grinding tool coated with or embedded with abrasive. Mainly used for grinding high-precision plane, internal and external cylindrical surface, conical surface, spherical surface, threaded surface and other surface.
