AI Technical Summary

Problems solved by technology

Due to the low grade of hydroxysilicate, about 0.17%, the composition of gangue is complex, including quartz, albite, potassium feldspar, fluorite, etc., and the properties of the ore are complex. A large number of literatures have been consulted. At present, there is no corresponding beneficiation process in China. Carry out the research and development of the flotation recovery technology of hydroxysilicate, provide a technically reasonable, economically feasible and efficient flotation recovery technology for the comprehensive recovery and utilization of this resource, and provide a demonstration role for the treatment of this type of ore

Embodiment 1

[0030] Embodiment 1: Actual ore open circuit test

[0031] Taking a beryllium ore in Xinjiang as the test object, the process flow chart used in the test is shown in figure 1 , the test results are shown in Table 1.

[0032] Table 1 Open circuit test results

[0033] product name

[0034] It can be seen from the results that the concentrate grade can reach 3.38%, the coarse concentrate recovery rate is 69.35%, and the concentrate + medium ore recovery rate can reach 92.11%.

Embodiment 2

[0035] Example 2: Small-scale closed-circuit test of actual ore in a beryllium mine in Xinjiang

[0036] In order to eliminate the influence of difficulties in flotation separation of middle ore, a small closed-circuit test was carried out on a certain beryllium ore in Xinjiang. For the process flow used in the test, see figure 2 , the results are shown in Table 2.

[0037] Table 2 Small closed circuit test results

[0038] product name

[0039] It is found that only 0.16% of the raw ore can be obtained, and the concentrate grade can reach 3.21%, and the recovery rate can reach 85.18%.

Abstract

The invention discloses an ore dressing method for bertrandite. The invention adopts the technical scheme that the method adopts a comminuting-flotation process, uses an inhibitor to inhibit gangue, uses an efficient activator to activate the beryllium ore and uses a collecting agent to float and reclaim beryllium. By treating the phenacite containing 0.17 percent of beryllium through the technology, the phenacite containing 3.21 percent of beryllium metal, namely 8.92 percent of beryllium oxide, can be obtained; the reclaiming rate reaches 85.18 percent; and the method can meet the requirement of good-quality raw materials smelted by beryllium ores, provides a new efficient path for comprehensive utilization of beryllium ore resources in China, and has the advantages of simple process flow, good effect, no pollution and the like compared with the current process for extracting the beryllium by a sulfuric acid method.

Description

technical field [0001] The present invention is a non-beryl beryllium ore beneficiation method, especially for beryllite-based beryllium ore, adopting advanced crushing-flotation technology, combined with high-efficiency flotation agents and reasonable agent system, to achieve The enrichment and separation of hydroxysilicate belongs to the technical field of rare metal beryllium ore flotation recovery. Background technique [0002] Beryllium has low density, high melting point and excellent dimensional stability.
