Embodiment 1

[0019] A kind of high-efficiency flotation method of beryllium ore provided by the invention is to process beryllium ore containing fluorite through the technological process of beryllium reverse flotation-beryllium forward flotation-beryllium reverse flotation again, and a certain beryllium ore in Yunnan is used as the test object. Containing BeO2.69%, F3.80%, BeO mainly exists in beryl and silicon beryllite, F exists in fluorite, fluorite accounts for about 7.8% of the total ore, and gangue minerals are mainly calcite and feldspar , quartz, fluorite, mica, etc. Although the BeO content of the ore is relatively high, because the ore contains a large amount of impurity minerals and harmful elements, the beryllium ore is currently only obtained by chemical acid leaching to obtain beryllium concentrate suitable for the production of beryllium oxide by the sulfuric acid method, and the recovery rate of beryllium is low. The production cost is high and the environmental pollution is

Abstract

The invention discloses a high-efficiency floatation method for beryllium ore. In the high-efficiency floatation method, a process flow of reverse beryllium floatation-direct beryllium floatation-re-reverse beryllium floatation is adopted to conduct mineral processing on the beryllium ore containing fluorite; firstly, the reverse beryllium floatation is used for floatation of gangue with better floatability to remove most of harmful element F and major impurity mineral (calcite) to improve the feeding quality of the direct beryllium floatation; secondly, the direct beryllium floatation is used for floatation of beryllium mineral to allow the beryllium mineral to be separated from the gangue difficult to float; and at last, the re-reverse beryllium floatation is used to remove little gangue from rough beryllium concentrate and ensure that F content in the beryllium concentrate meet the requirement of industrial production. The process flow of the floatation method fully conforms to the characteristic of floatability of various minerals; a flow structure and a reagent system are simple; the adaptability to water temperature and water quality is high; the production operation is easy to control; the index of mineral processing is good; and the resource utilization rate is high.
