Abstract
The invention relates to a floating and collecting agent of bertrandite beryllium ores and application thereof. In the invention, benzohydroxamic acid is used as an organic compound collecting agent, and after benzyl is introduced to hydroximic acid, the selective collecting capacity to beryllium ores of hydroximic acid medicaments is improved. The floating and collecting agent is used for the flotation of the bertrandite beryllium ores, has excellent selective collecting property and is a high-efficiency floating and collecting agent for the beryllium ores.
Description
Technical field
The invention belongs to floating agent field, rare metal ore deposit, relate to a kind of flotation collector, particularly a kind of flotation collector and application thereof that is applicable to bertrandite class beryllium ore deposit.
Background technology
It is reported, beryllium belongs to rare metal, average content in the earth's crust only is 0.0003%, but it has excellent physical and mechanical property, being widely used in industries such as atomic energy industry, space flight and electronics, particularly being called as " nuclear age metal " and " cosmic time substituting metal " because of its extensive application on X-ray tube, is a kind of deoxidier and additive that is used for various alloys, have the title of " glassy metal ", have very vast market prospect.China's beryllium ore resources is very abundant, and all there is output in 15 provinces (district), and there are 77 places in the mining area of proved reserves, and total reserves occupies the second place of the world.Wherein maximum with Xinjiang beryllium reserves, explored beryllium ore resources storage level accounts for more than 70% of the whole nation in the fuyun border of the county.The beryllium ore resources is based on beryl, but not the Application and Development of the Beryllia-ore resource of beryl type relative difficult then.
Mineral collector has many types, and up to now, the most frequently used oxide ore collecting agent is still amine, sulfonic acid, fatty acid and their derivative.The hydroximic acid collecting agent is as a kind of collecting agent of oxide ore preferably, to multiple oxide ore and part oxidized sulphide ore good collecting performance is all arranged.Benzene first hydroximic acid is stronger than general hydroximic acid collecting ability as a kind of cycloalkanes hydroximic acid collecting agent, the rare metal oxide ore is all had stronger collecting ability, and selectivity is better.At present, the application that is used for the Beryllia-ore flotation about benzene first hydroximic acid does not appear in the newspapers, and the application of developmental research bertrandite class Beryllia-ore resource high-efficiency flotation collector has great importance.
Summary of the invention
At the problem of bertrandite class Beryllia-ore resource flotation collecting weak effect, the purpose of this invention is to provide a kind of efficient flotation collector with high selectivity, strong collecting ability, be used as the use of the flotation collector in bertrandite class beryllium ore deposit.
The objective of the invention is to realize by following manner:
A kind of bertrandite class beryllium ore deposit flotation collector is the compound benzene first hydroximic acid shown in the formula 1.
Formula 1
The collecting agent of using the above is in the ore deposit flotation of bertrandite class beryllium.The consumption of described flotation collector is the 500g/t-2000g/t ore.
Above-mentioned flotation collector and oleic acid cooperate emulsification to use better effects if.
The present invention introduces the hydroximic acid medicament with the naphthene group benzyl, improves the selectivity collecting ability of hydroximic acid medicament to bertrandite class Beryllia-ore.
The present invention has the following advantages when being used for the flotation of bertrandite class beryllium ore deposit:
1. because this kind collecting agent has been introduced benzyl, the agent molecule volume is big, is faintly acid, compared with other alkyl hydroximic acid, better can with mineral generation chemisorbed, therefore have good selectivity collecting ability, the Beryllia-ore of the bertrandite of flotation collecting efficiently class.
2. shortcomings such as when having overcome traditional flotation technology and handling Beryllia-ore, collecting poor effect, the rate of recovery are lower, reagent cost height have new breakthrough on mineral processing index.The present invention carries out comparing when the flotation of beryllium ore deposit is reclaimed with oleic acid with single, and the rate of recovery can improve at least 5%, has more superior collecting performance.
The specific embodiment
Embodiment 1
Adopt collecting agent of the present invention: molecular formula is C
7H
7NO
2, benzene first hydroximic acid has carried out laboratory flotation research to Hunan Beryllia-ore ore, and its main berryllium mineral is a Beryllia-ore, other metalliferous minerals of association, main gangue mineral is quartz, calcite, feldspar etc.Beryllium content is about 0.10% in this ore, and its main berryllium mineral is a bertrandite, accounts for about 90%.Because head grade is lower, the gangue content complexity, bertrandite and gangue separation difficulty, this ore belongs to more unmanageable Beryllia-ore ore.Because the more difficult collecting of Beryllia-ore, at ore character, in conventional oxidation ore deposit flotation treatment process, add collecting agent 800g/t of the present invention, stirred terpenic oil 20g/t 15 minutes, stirred 3 minutes, flotation 6-9 minute, can obtain to contain beryllium 0.72% by one roughing, primary cleaning, the beryllium concentrate of the rate of recovery about 70%.The result has reached floating and enriching effect preferably, and the rate of recovery of berryllium mineral is also higher, this shows that high-efficient collecting agent of the present invention can be good at the collecting Beryllia-ore.
Embodiment 2
Closed-circuit test
Adopt collecting agent of the present invention: molecular formula is C
7H
7NO
2, benzene first hydroximic acid cooperates oleic acid (1: 1) emulsification to use, and Beryllia-ore actual ore in Xinjiang is carried out small-scale test, has obtained the good technical index.Low temperature hydrothermal volcanic type mineral deposit during beryllium ore deposit, Xinjiang belongs to, mineralising is produced in tufa stone, and ore body is tabular extension.Substantially, the beryllium oxide reserves of verifying have more than 500 ton, but the beryllium oxide grade is lower.Show that according to the process mineralogy analysis result beryllium ore deposit, mining area ore raw ore beryllium grade is low, is 0.17%, main berryllium mineral is a bertrandite, accounts for 95%, and gangue has quartz, albite, potassic feldspar, fluorite etc., ore character complexity.Owing to a large amount of siliceous minerals is arranged in the ore, selectivity collecting bertrandite is difficulty very, and beryllium is inlayed comparatively complexity of relation, monomer dissociation difficulty with gangue mineral.Therefore raw ore is milled to fineness through primary grinding and accounts for 90% for-0.074mm, adds earlier and adjusts the agent activation, adds described collecting agent 2000g/t then, 2
#Oil 20g/t carries out flotation, and the main flow process of flotation is one thick four single-minded sweeping, and can obtain to contain beryllium 2.86%, the beryllium concentrate of the rate of recovery 75.6%.Following table 1 is for adopting collecting agent of the present invention to Xinjiang beryllium uranium leached mud flotation closed-circuit test result.
