Abstract
The invention discloses a beryllia-ore combination activator and an application thereof, belonging to the field of mineral dressing and rare and noble metals comprehensive utilization. The combination activator comprises 0.8-1.5 sodium fluoride (NaF), 2.4-4.5 sodium sulfide (Na2S) and 0.04-0.75 calgon (NaPO36) in mass ratio, wherein the optimal ratio is 1:3:0.05. When in use, 800-1500g of sodium fluoride is firstly added in ore per ton, 2400-4500g of sodium sulfide and 40-75g of calgon are added later in ore per ton during grinding ore, stirring and size mixing are carried out for 20-4min andsubsequent flotation collection is carried out. The activator not only can clean surface of beryllia-ore but also can effectively activate beryllia-ore, thereby being beneficial to floating collection of beryllia-ore and enhancing ore dressing index of beryllium concentrate.
Description
Technical field
The invention belongs to non-ferro metals floatation medicament and rare metal comprehensive reutilization field, relate to a kind of flotation combination activator, particularly a kind of efficient flotation combination activator and application thereof that is applicable to Beryllia-ore.
Background technology
In flotation technology, effectively the useful purpose mineral of activation are the key points that realize the flotation collecting.The rare metal beryllium is the important materials in the industry.Industrial beryllium major part is used for the production of beallon with the beryllium oxide form, and fraction is used with the metallic beryllium form, and other has a small amount of as beryllium oxide ceramics etc.Particularly atomic energy, aerospace and fields such as aviation, metallurgy have important use.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 main with beryl, but not the Application and Development of the Beryllia-ore resource of beryl type relative difficult then.
At present, the exhaustion day by day of China's rare metal beryllium resource, the source of expansion resource is improved resource utilization and is become one of important channel that solves resource scarcity.Traditional floatation process of rare metal beryllium rests on flotation always and handles on the beryl, and the Research on Flotation that contains berryllium mineral is then less relatively.The activation problem that the big factor that restriction Beryllia-ore flotation technology improves is exactly a Beryllia-ore.Beryllia-ore flotation activating is efficiently explored in research, promotes the flotation of Beryllia-ore resource and utilizes level, and comprehensive lifting beryllium industry technology level is had important function.
Summary of the invention
When the present invention is directed to the flotation Beryllia-ore, the problem of purpose mineral activation relative difficult provides a kind of combination of the flotation activating of Beryllia-ore efficiently and application process thereof with strong selectivity, in order to active oxidation beryllium ore deposit in the flotation.
The objective of the invention is to realize through following manner:
A kind of Beryllia-ore combination activator consists of: the mass ratio of sodium fluoride, vulcanized sodium and calgon is 0.8-1.5: 2.4-4.5: 0.04-0.75.Be preferably 1: 3: 0.05.
The application of described combination activator is; In grinding process, add sodium fluoride 800-1500g/t ore; Then add vulcanized sodium 2400-4500g/t ore and calgon 4 ~ 75g/t ore, carry out the stirring of 20-40min and size mixing, carry out follow-up flotation collecting again.
The present invention removes the ion on Beryllia-ore surface with sodium fluoride (NaF), uses vulcanized sodium (Na again
2S) calgon [(NaPO is used in the interference of elimination alkaline-earth metal then
3)
6] regulate ore pulp, thus reach the purpose in active oxidation beryllium ore deposit.
In the former Beryllia-ore flotation technology, often only be to use hydrofluoric acid or sodium fluoride and sulfuric acid etc. to handle ore pulp, add collecting agent and foaming agent flotation after the activation, this activator only utilizes F
+The activation siliceous mineral, but a lot of siliceous gangue mineral floats easily together, causes the flotation grade and the rate of recovery lower.The present invention discovers at the Beryllia-ore grinding process, is easy to generate a large amount of metal ions, like Ca
2+, Mg
2+Deng, these ions easily attached to the Beryllia-ore surface, hinder collecting agent and the effect of purpose mineral and Ca in the Beryllia-ore floatation process
2+Existence also can the activation gangue mineral, like the come-up effect of mineral such as quartz, thereby cause the Beryllia-ore flotation effect not good, in Beryllia-ore floatation process in the past, seldom notice.Combination activator of the present invention uses sodium fluoride to cooperate the calgon effect to eliminate the influence of calcium, magnesium ion; Eliminate the influence of other metal ions with vulcanized sodium; Surface, clean oxidation beryllium ore deposit is eliminated the flotation GOLD FROM PLATING SOLUTION and is belonged to the effect of ion, thereby makes F to greatest extent
+Can the siliceous Beryllia-ore mineral of selectivity activation, better active oxidation beryllium ore deposit flotation effect after combination is used.
The present invention has the following advantages when being used for Beryllia-ore flotation activation:
Because this efficient combined modifier has the high selectivity activation, can be in the Beryllia-ore flotation efficient activation purpose mineral, reach the purpose of flotation collecting.
When the efficient combination activator of flotation of the present invention was used for the Beryllia-ore flotation, when using sodium fluoride than list, mineral processing index was better, and therefore, this combination activator has advantages such as effective, pollution-free.
The specific embodiment
Embodiment 1
Adopt combination medicament of the present invention (seeing table 1): sodium fluoride (NaF), vulcanized sodium (Na
2S) with calgon [(NaPO
3)
6] respectively by 0.8: 2.4: 0.04, with 1.5: 4.5: 0.075 ratio combination use at 1: 3: 0.05, the Xinjiang Beryllia-ore is carried out flotation research; Its main berryllium mineral is a bertrandite; And association other like metalliferous minerals such as pyrite, main gangue mineral has quartz, albite, potassic feldspar, fluorite etc., ore character is complicated; Bertrandite and gangue separation difficulty, this ore belong to more unmanageable Beryllia-ore ore.Because the more difficult flotation collecting of Beryllia-ore, to ore character, in ore grinding, add sodium fluoride (NaF) 800g/t, 1000g/t, 1500g/t respectively, be milled to-0.074mm accounts for 90% fineness, then adds vulcanized sodium (Na respectively
2S) 2400g/t, 3000g/t, 4500g/t and calgon [(NaPO
3)
6] stirring carried out about 30min of 40g/t, 50g/t, 75g/t sizes mixing; Add Beryllia-ore fatty acid collecting agent and foaming agent and carry out the flotation collecting, flotation is about 8 minutes, can obtain the beryllium concentrate of preferable index through sorting operation; The result is better than single effect with sodium fluoride (NaF) activation; It is thus clear that adopt combined modifier to can be good at active oxidation beryllium ore deposit, regulate the flotation pulp system, help the flotation collecting of Beryllia-ore.
