Background technique
Copper is one of metal that the mankind use earliest and the national economic development and the important former material for ensureing national defense safety
Material is widely used in the fields such as electrical, light industry, machine-building, building industry, national defense industry, in China's nonferrous materials
Consumption in be only second to aluminium.China is copper resource big country, but the consumption figure growth rate of copper is significantly greater than production increase in recent years
Speed.It is universal with the quickening of the infrastructure constructions such as communication, electric power and automobile and IT product, it is Chinese from now on right
The demand of copper products will continue to increase substantially.But with a large amount of exploitations of resource, the increasingly poor thin hydridization of copper resource gives copper resource
It is efficient using affecting.The separation of quartz, magnetic iron ore contained in copper sulfide mineral and ore etc. is ore dressing field public affairs
The technical problem recognized, domestic and international researcher have conducted extensive research such ore.
The difficult point that copper sulfide mineral is separated with magnetic iron ore is: the 1. close symbiosis of valuable mineral, disseminated grain size thickness is not
, easily cause part mineral overground in dissociation process；2. floatability is not much different between sulfide mineral, recovery process is complex.
In general, the number of magnetic iron ore content and the quality of floatability in such ore, directly affect floatation indicators.Magnetic Huang iron
When mineral content is more, the dosage of inhibitor is more, and the use of a large amount of inhibitor is unfavorable to the flotation of copper mineral, and the copper concentrate rate of recovery is not
Easily improve.
Therefore, exploitation to quartz and magnetic iron ore have more highly selective inhibitor, realize copper sulfide mineral and quartz,
Magnetic iron ore and pyrite efficiently separate, and are of great significance to the efficient utilization for realizing difficult copper-sulphide ores.
Summary of the invention
The present invention is to solve the ore dressing skill of the gangue minerals such as copper sulfide mineral and magnetic iron ore, quartz FLOTATION SEPARATION low efficiency
Art problem provides and a kind of improve difficult copper sulfide ore beneficiation and refer to calibration method.
This method comprises the following steps:
(1) ore grinding: by difficult copper-sulphide ores ore grinding, ore grinding ore pulp is obtained, the fineness of grinding operation is that -0.074mm is accounted for
65%-80%；
(2) the regulator dilute sulfuric acid that concentration is 5%-10% is added in the ore pulp that step (1) obtains, by the pH value of ore pulp
It is adjusted to 4-7；
(3) it a certain amount of micro-size fraction serpentine minerals is added in the ore pulp that step (2) obtains is stirred and size mixing, adjust
The slurry time is 5-10min；
(4) inhibitor calcium lignosulfonate, collecting agent butyl xanthate, foaming agent 2 are sequentially added in the ore pulp obtained by step (3)
Number oil, which is stirred, sizes mixing, wherein and calcium lignosulfonate dosage is 300-500g/t, and butyl xanthate dosage is 100-200g/t, No. 2
Oily dosage is 10-30g/t；
(5) roughing that the ore pulp after step (4) dosing is carried out to copper sulfide mineral, obtains rougher concentration and rougher tailings；
(6) being added in the rougher concentration that step (5) obtains has the regulator progress of divergent function selected twice, obtains
Final concentrate, selected chats sequence return to upper level operation；
(7) No. 2 oil of collecting agent butyl xanthate and foaming agent are added in the rougher tailings that step (5) obtains to be swept twice
Choosing, obtains true tailings, scans chats sequence and returns to upper level operation；Wherein, butyl xanthate dosage is 20-60g/t, and No. 2 oil are used
Amount is 10-20g/t.
Wherein, in step (1) difficult copper-sulphide ores be containing quartz, magnetic iron ore, pyrite copper-sulphide ores.
The purity of added serpentine is 70-100% in step (3), and the granularity of serpentine particles is that -0.010mm grade contains
Amount accounts for 60-100%, and the amount of the serpentine of addition is 1000-8000g/t.
The regulator being added in step (6) is one of sodium pyrophosphate, calgon, tertiary sodium phosphate, added adjustment
The dosage of agent is 200-500g/t.
The copper grade that step (6) obtains final concentrate is greater than 20%, and copper recovery is greater than 80%.
The advantageous effects of the above technical solutions of the present invention are as follows:
The present invention uses mineral as floating agent for the first time, and it is mainly magnetic that hydrophilic serpentine minerals, which are introduced gangue mineral,
The copper-sulphide ores FLOTATION SEPARATION field of pyrite and quartz, pyrite, utilizes serpentine, quartz, magnetic iron ore, pyrite, Huang
The surface property differences of copper mine make hydrophilic serpentine minerals selective absorption in magnetic iron ore, pyrite, quartz surfaces and press down
Make its floating, realize gangue mineral be mainly magnetic iron ore, quartz, pyrite copper-sulphide ores efficient flotation separation.Use snake
Stone ore object is good to gangue mineral inhibitory effect as inhibitor, while reducing the dosage of chemical agent, is a kind of stabilization, height
Effect, the difficult copper sulfide ore beneficiation method of environmental protection.
