Description
Technical Field
The application belongs to the technical field of ore floatation, and particularly relates to a compound collector for lepidolite ore floatation based on an anion-cation effect and application thereof.
Background
The mica mineral resources are abundant in China, and are widely used in the national economy fields of electronics and appliances, construction industry, special materials and the like due to the unique heat resistance, insulation and stability, and meanwhile, the mica mineral can also be used as a mineral carrier of valuable metals such as lithium, niobium and uranium, for example, lepidolite, niobium-rich biotite, uranium-bearing mica and the like. The lepidolite is used as a lithium-containing mineral with larger reserves in China, and is one of the most important resources for extracting lithium elements. In recent years, along with the consumption and utilization of high-quality lepidolite mineral resources, more and more difficult low-quality ores are the current difficult problems to be solved in the lepidolite ore flotation field.
The common collector in the lepidolite flotation process at the current stage still takes a single cationic amine collector as a main component, and the solubility of the traditional amine collector can be ensured in an acidic environment due to the small solubility of the traditional amine collector, so the traditional amine collector is suitable for lepidolite flotation in the acidic environment, the dispersion of the traditional amine collector needs to be maintained by heating at low temperature, and the use condition is limited by the environment; meanwhile, the large amount of acid solution used in the flotation process can cause corrosion to equipment and pollution to the environment, so that the production cost is increased; for other oxidized ore flotation collectors, the problems of poor selectivity, weak collecting capacity and the like exist, and the existing low-Li flotation collector is difficult to adapt to 2 Lepidolite ore with high O grade and slime content. Compared with single anion and cation collecting agents, anion and cation effect product and complex thereofThe compound has the advantages of good water solubility and dispersibility, good foam strength, simple and effective medication system, good low temperature resistance, simple operation, environmental friendliness, good selectivity, high lepidolite recovery rate and great application prospect in mineral flotation, and can effectively reduce the production cost.
In the field of mineral flotation, there is a great deal of attention to the targeted regulation of hydrophobic groups of collectors, such as amphiphilic mineral structure collectors, gemini type cationic collectors, and the like, where two amphiphilic mineral groups or two hydrophilic groups and two hydrophobic groups are skillfully linked by an intermediate linking group. And the compound collector can realize the regulation and control of the ester group, the hydroxyl structure, the number and the number of alkoxy chains, and provides a design idea for realizing selective and efficient flotation. At present, no report about the application of an anion-cation effect product and a compound thereof to lepidolite mineral flotation technology is found in the prior art.

For example, a range of 1-50 should be understood to include any number, combination of numbers, or subranges of numbers selected from 1,2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50, as well as all fractional values between the integers described above, such as 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, and 1.9. Regarding sub-ranges, specifically considered are "nested sub-ranges" that extend from any end point within the range. For example, the nested subranges of exemplary ranges 1-50 can include 1-10, 1-20, 1-30, and 1-40 in one direction, or 50-40, 50-30, 50-20, and 50-10 in another direction.
