Abstract
The invention discloses a novel combined collecting foaming agent for sorting copper ores in alpine regions and application thereof, and is characterized by comprising 2-5 parts of azothionitrile ester, 1-2 parts of ammonium butryate, 0.25-0.5 part of diesel oil, 0.5-0.75 part of ethanol and 1-2 parts of 43# cyanic ester, so that the problems that in the winter production process of copper mines in alpine regions, the outdoor temperature reaches below-20 to 30 ℃, and the currently used ester collecting agent is high in melting point and easy to crystallize, inconvenience is brought to production, and production indexes are affected are solved.
Description
Technical field
The present invention relates to Copper Ores collector and frother technical field is sorted, in particular to a kind of extremely frigid zones sort copper mine
The novel compositions collector and frother of stone and application.
Background technique
In extremely frigid zones, since winter temperature is lower (individual places reach subzero 20 DEG C, refer to medicament storage temperature),
This just gives the bargh produced in winter to bring larger impact: the ore and industrial water in workshop region, stockyard when 1, producing
Temperature is all lower, causes Copper Ores selecting factory's production process Chinese medicine mineralising bad, to affect index；2, common efficient
Select copper esters medicament to be easy to produce crystallization at low ambient temperatures, and it is most common select copper medicament ester -105, at 23 DEG C of room temperature or less
Just gradually crystal, to selecting factory's production to make troubles.Therefore needing to heat its medicament in advance in process of production could use, if plus
Heat is not thorough, and medicament mineralising is bad, not only dosing is increased, and has an effect on production target, finally reduces the warp of enterprise
Ji benefit.
Summary of the invention
The present invention provides novel compositions collector and frother and the application that a kind of extremely frigid zones sort Copper Ores, for mesh
The live winter Copper Ores collector and frother of preceding extremely frigid zones is easy crystallization, leads to the problem that production target is lower, provides one kind
It does not crystallize at low ambient temperatures, and the novel compositions collector and frother for selecting factory's production target can be improved.
To achieve the goals above, technical solution of the present invention is specific as follows:
A kind of extremely frigid zones sort the novel compositions collector and frother of Copper Ores, including 2~5 parts of ester of sulphur nitrogen nitrile, and butyl ammonium aerofloat 1~
2 parts, 0.25~0.5 part of diesel oil, 0.5~0.75 part of ethyl alcohol, 1~2 part of 43# Huang hydrocyanic ester.
The invention also discloses the applications that a kind of extremely frigid zones sort the novel compositions collector and frother of Copper Ores, including such as
Lower step:
It (1) is that -0.074mm accounts for 70%~85% by Copper Ores wet-milling to granularity, ore milling concentration 50~60%, the stone in grinding process
Ash, additional amount are 500g/t~3000g/t；
(2) flotation pulp mass percentage concentration being adjusted 30~40%, is added common collecting agent butyl xanthate, dosage is 10~
Then the novel compositions collector and frother that a kind of extremely frigid zones described in claim 1 sort Copper Ores is added in 40g/t, be added
Amount be 30~50g/t, by roughing, it is selected, scan, output copper concentrate and tailing.
The beneficial effects of the present invention are:
1, using alcohols and the lower melting-point physical property of petrochemicals, the molten of new ester combination collector and frother is reduced
Point eliminates conventional esters collector and frother and crystallizes the link that need to be heated, and increases dissolution dispersion degree of the medicament in ore pulp,
Reduce collecting agent consumption, improves mineral processing index, reduce costs；
2, the sulphur nitrogen nitrile ester in the present invention, butyl ammonium aerofloat, diesel oil and the combination of 43# Huang hydrocyanic ester play the work of efficiency complementation
With reinforcement adds low melting point ethyl alcohol as lytic agent, so that novel group provided by the invention to the selection collecting sexuality of copper
It is simple to close collector and frother composition, stability is good, simple process, production cost are low, have stronger selection collecting frothing capacity,
Environmental pollution is less, realizes valuable metal synthetical recovery.
