Description
Technical field
The present invention relates to Oxide Copper Ore Flotation separation technology field more particularly to a kind of collectings for Oxide Copper Ore Flotation
Agent preparation method.
Background technique
Currently, copper is a kind of very important metal during national product, there is good ductility and electric conductivity, and
Easily with multiple element component alloy, it is widely used in the industries such as electronics, building, national defence, machinery, light industry.The main source of copper has
Copper-sulphide ores and cupric oxide ore, but a large amount of consumption with socio-economic development to copper, are industrially easily selecting copper-sulphide ores reserves just
It sharply reduces, is gradually difficult to meet the needs of China's economy fast development, therefore the exploitation of cupric oxide ore gradually causes people's
Pay attention to.Cupric oxide ore stock number accounts for 1/4 or so of China's copper resource total amount, is the important component of China's copper resource.So
And the floatability difference of different types of cupric oxide ore is larger, has malachite, cuprite, chessy copper as floatability is stronger, and
Then floatability is relatively poor for warringtonite, chrysocolla.
Since cupric oxide ore structure species are more, oxygenation efficiency with higher and Percentage bound, and mineral granularity is thin, embedding cloth
Unevenly, hydrophily is strong, clay content is high, while a variety of useful elements of association, and therefore, the development and utilization of refractory copper oxide, which become, grinds
Study carefully emphasis.Sulfide flotation method is a kind of common method during cupric oxide ore development and utilization, generallys use the preparatory sulphur of vulcanized sodium
After change, then with advanced xanthate or other sulfide mineral collectors flotation is carried out to it, but uses such collecting agent one in the prior art
The disadvantage of a maximum is that the rate of recovery is lower.
Summary of the invention
The object of the present invention is to provide a kind of collecting agent preparation method for Oxide Copper Ore Flotation, prepared by this method
Collecting agent has the advantages that collecting ability is strong, dosage is few, and the conventional collecting agent such as can effectively replace xanthate, facilitates when sulfide flotation
Improve oxidation copper recovery.
A kind of collecting agent preparation method for Oxide Copper Ore Flotation, which comprises
It is step 1, a certain proportion of dihydrocarbyl dithiophosphate ammonium phosphate and 2- carboxymethyl thioether group -5- alkyl benzimidazole is pre-
First mix；
Then step 2 is added ethanol in proper amount as solvent, and is sufficiently mixed；
A small amount of diesel adjuncts are added in said mixture by step 3 again, and collecting further is prepared after mixing
Agent.
The quality component of each raw material is respectively as follows:
20-40 parts of dihydrocarbyl dithiophosphate ammonium phosphate, 30-70 parts of 2- carboxymethyl thioether group -5- alkyl benzimidazole；
And the ethyl alcohol of 1-10 parts of diesel oil and 1-10 part.
The quality component of each raw material is further are as follows:
30 parts of ammonium dibutyl dithiophosphate, 60 parts of 2- carboxymethyl thioether group -5- butyl benzimidazole；
And 5 parts of diesel oil and 5 parts of ethyl alcohol.
When in use, be configured to mass fraction with soda ash or sodium hydroxide is the water-soluble of 5-10% to prepared collecting agent
Liquid.
As seen from the above technical solution provided by the invention, collecting agent prepared by the above method has collecting ability
By force, the few advantage of dosage, the conventional collecting agent such as can effectively replace xanthate, helps to improve oxidation copper recovery when sulfide flotation,
Have the characteristics that can be widely applied to cupric oxide ore, copper-sulphide ores, vulcanization-oxidization copper mine using safe, addition is convenient simultaneously
Flotation.
