Abstract
The present invention provides a kind of combined flotation agent for the carbon containing Pyrite-type gold ore flotation of high arsenic.The combined flotation agent is by having [CSx]2‑The floating agent of functional group and have R-OCSS‑The floating agent of functional group is composed according to weight ratio 1:1-1:5 proportion, and wherein the value range of x is 3-5, and R is the alkyl with 4-6 carbon atom.The present invention also provides the applications of the combined flotation agent, and under equivalent pharmaceutical dose dosage, combined flotation agent of the invention can effectively improve the grade and the rate of recovery of the carbon containing Pyrite-type gold mine of high arsenic, greatly utilize mineral resources, improve income.
Description
Technical field
The invention belongs to mineral floating field more particularly to a kind of combinations for the carbon containing Pyrite-type gold ore flotation of high arsenic
Flotation agent and its application.
Background technique
Gold gets more and more people's extensive concerning as a kind of most rare, most precious one of metal, it is not only economically
There is critical role with industrial, while being also the special currency for laying in and investing.The existing gold ore place of production 2000 in China
Many places, gold deposit geology resource have the characteristics that few big mine, small scale, grade be low, resource dispersion.To the end of the year 2002, China's independence
Gold mine reserves is about 3000t, and wherein difficult separation ore resources reserves account for about 1000t or so.Arsenic content is 0.1% or more
Ore is the important component of typical difficult-treating gold mine and China's gold ore resource, in the southwest, northwest and northeast in China
Area is distributed.
The golden resource in China is largely to exist in the form of Independent Mineral and microinclusion, with opening for gold resource
Hair, the golden resource being present in pyrite in the form of Independent Mineral is fewer and fewer, and in the form of microinclusion existing for mineral deposit
As main gold resource., the collecting identical as the floating principle in sulphide ore mineral deposit by the mineral deposit of gold-carrying minerals of pyrite
The kind of agent is more, important is xanthate and its lipid, thio-alcohol, black powder class and sulphur gland class collecting agent, and gold-carrying minerals arsenic yellow
The recycling relative difficulty of iron ore.Studies have shown that carry mock gold in floatation process and be easier to adsorb S element than mispickel,
Surface-active is higher, thus has the higher rate of recovery;And with the increase of arsenic and golden percentage composition in mispickel,
The rate of recovery reduces.And not only mispickel activity is lower in the high carbon containing Pyrite-type gold mine of arsenic, influences grade and the rate of recovery, wherein
Carbonaceous to gold have suction-operated and the ore grinding stage be easy argillization, flotation is adversely affected.
At present for the carbon containing Pyrite-type gold mine of high arsenic common collecting agent have ethyl xanthate, butyl xanthate, cresols black powder,
Butyl ammonium aerofloat and oleic acid etc., new collector such as Y89 series collecting agent use six that MIBC, CS2 and NaOH are raw material production
Carbon alcohol xanthate, since it is with special molecular structural formula and longer carbochain, so that it is strong with excellent selectivity and relatively
Collecting ability, be the common collecting agent of gold ore.In addition, it was verified that combination medicament is used in floatation process, because of medicament
Between synergistic effect, can further improve the performance of floating agent, this is also the effective way for improving difficult ore dressing floatation indicators.Mesh
Before, in gold flotation production, the most common combined capturing and collecting agent is that amyl group xanthate is combined with butyl ammonium aerofloat, but the combination medicament is to arteries and veins
There is flotation selectivity difference in the gold mine of the easy argillization of stone ore object.Therefore, what the present invention was studied is used to effectively recycle high arsenic
The combined flotation agent of carbon containing Pyrite-type gold mine is of great significance to actual industrial.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the shortcomings of to mention in background above technology and defect, provide one
Kind is used for the combined flotation agent of the carbon containing Pyrite-type gold ore flotation of high arsenic, which can successfully realize gangue mineral and carry
Effective FLOTATION SEPARATION of gold mineral under the conditions of gold grade is higher in guaranteeing concentrate, improves the rate of recovery of gold;The present invention is also
The application of the combined flotation agent is accordingly provided.
In order to solve the above technical problems, technical solution proposed by the present invention are as follows:
A kind of combined flotation agent for the carbon containing Pyrite-type gold ore flotation of high arsenic, the combined flotation agent is by having
[CSx]2-The floating agent of functional group and have R-OCSS-The floating agent of functional group is matched according to weight ratio 1:1-1:5 and is combined
It forms, wherein the value range of x is 3-5, and R is the alkyl with 4-6 carbon atom.
In the carbon containing Pyrite-type gold mine of high arsenic of the invention, arsenic content is greater than 3%, carbon content 1%-2%.
Combinations of the above flotation agent, it is preferred that described that there is [CSx]2-The floating agent of functional group is more thiocarbonates.
It should be pointed out that this has [CSx]2-The floating agent of functional group need to be prepared at normal temperatures and pressures, by adding flotation drug
Enter in water and stir that 5min is produced above, floating agent obtained is the red solution of transparence.
Combinations of the above flotation agent, it is preferred that described that there is R-OCSS-The floating agent of functional group is ethyl xanthate, different
One of butyl xanthate, isoamyl xanthate are a variety of.
The inventive concept total as one, the present invention also provides a kind of combinations of the above flotation agent to contain carbopyrite in high arsenic
Application in type gold ore flotation, the application process adjust ore pulp the following steps are included: adding pH regulator first in ore pulp
Then pH value adds copper sulphate for activation gold-carrying minerals (including carry mock gold and carry golden mispickel), then to add combination floating
Agent is selected, foaming agent is finally added, flotation operation is carried out later, obtains flotation concentrate.
Above-mentioned application, it is preferred that the mass fraction of the ore pulp is 17%-25%, and the pH value for adjusting the ore pulp is
8-10。
Above-mentioned application, it is preferred that based on ore pulp per ton, the dosage of the pH regulator is 750-1250g/t, the sulphur
The dosage of sour copper is 25-75g/t, and the dosage of the combined capturing and collecting agent is 250-400g/t, and the dosage of the foaming agent is 60-
84g/t。
Above-mentioned application, it is preferred that the pH regulator is sodium carbonate.
Above-mentioned application, it is preferred that be additionally added waterglass in application process as gangue sludge inhibitor and dispersing agent, press
Ore pulp meter per ton, the dosage of the waterglass are 750-1250g/t.
Above-mentioned application, it is preferred that the foaming agent be alcohol, carboxylic acid and rouge mixture, concrete model RB1, RB2,
One of RB3 or a variety of.The foam in ore pulp can be increased by adding foaming agent, keep foam more stable, with collecting agent phase
