Abstract
The invention relates to a composite copper ore collector which is a powdery material. The powdery material contains sodium n-butyl-xanthate and sodium n-nonyl-xanthate in a weight ratio of (7-10):1. The composite collector provided by the invention not only contains the sodium n-butyl-xanthate having strong hydrophobic action on sulfides of copper in the copper ore, but also contains the sodium n-nonyl-xanthate having strong hydrophobic action on oxides of copper in the copper ore. The major components of the composite collector are the sulfides of copper, and the minor components are the oxides of copper; and the composite collector has favorable floatation effect on the copper ore.
Description
Technical field
The copper mine collecting agent of using when the present invention relates to a kind of flotation, particularly a kind of composition of copper mine collecting agent.
Background technology
Useful composition and useless gangue in the mineral.Mineral floating is to use various medicaments to regulate selected mineral grain Surface Physical chemical property, thereby the parent of enlarged metal mineral and gangue and flotation medium, thin difference makes it in the sorting better of selected introductions matter, reaches the purpose of the useful composition rate of recovery of raising.Flotation medium commonly used is a water, and flotation agent commonly used divides three major types: collecting agent, foaming agent, adjustment agent.
Water will make the mineral grain surface hydrophobicity during as flotation medium flotation metalliferous mineral, comes the mineral grain emersion after hydrophobic with foaming agent again.
Occurring in nature has the natural floatability except that mineral grain surface hydrophobicities such as coal, graphite, Sulfur, talcum and molybdenites, and most of mineral all are hydrophilic.Hydrophobic mineral can be separated with the method for flotation and hydrophilic mineral, and the stronger floatability of the hydrophobicity of mineral is high more.Can make mineral grain change into hydrophobic and make mineral grain have floatability from hydrophilic after with medicament is handled hydrophilic mineral grain, this medicament is referred to as collecting agent usually.Collecting agent is a kind of surfactant; The collecting agent molecule is by forming with mineral grain the surface group of having an effect and the group two parts that play hydrophobic effect; When adsorption of collector in ore particle when surface, its molecule is and aligns, the group that can have an effect with the mineral grain surface is towards the mineral grain surface; The group that plays hydrophobic effect forms hydrophobic membrane outwardly, and the surface that makes mineral grain is changed into hydrophobic and made mineral grain have floatability from hydrophilic.The surface nature difference of mineral grain is also very big, and the kind of collecting agent is a lot, and different mineral need use different collecting agents to handle could produce preferable floatability.
Occurring in nature because copper and sulphur have stronger binding ability, so copper mine stone general most all be the sulfide of copper.The grade of the copper mine stone after the general exploitation is not high, in order to improve the efficient of smelting, will use the copper in the method enriching Cu ore of flotation to exploiting the not high copper mine stone of back grade, obtains the higher copper concentrate of grade.
In the prior art, used collecting agent is a powder shape material during floating copper ore, and its composition is a sodium n-butyl-xanthate.This floating copper ore is with having only a kind of active ingredient of sodium n-butyl-xanthate in the composition in the collecting agent, sodium n-butyl-xanthate is stronger to the hydrophobic effect of the sulfide of copper, and is when floating copper ore, better to the copper mine stone flotation effect of the sulfide that only contains copper.
In some copper mine stone; Though main a large amount of composition is the sulfide of copper; But the oxide that also has little copper; The oxide of copper is the copper of difficult choosing in the copper mine stone, and sodium n-butyl-xanthate is not very strong to the hydrophobic effect of the oxide of copper, so the above-mentioned collecting agent that has only a kind of active ingredient of sodium n-butyl-xanthate is that a spot of composition of sulfide of copper is that the hydrophobic effect of copper mine stone of the oxide of copper is not fine to some main a large amount of composition; When floating copper ore, better to the copper mine stone flotation effect of the sulfide that only contains copper.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, proposing a kind of is that a spot of composition of sulfide of copper is the compound preferably copper mine collecting agent of copper mine stone flotation effect of the oxide of copper to main a large amount of composition.
The present invention realizes with following method.
Compound copper mine collecting agent is a powder shape material, and sodium n-butyl-xanthate and nonyl sodium xanthogenate are arranged in the powder shape material, and the weight ratio of sodium n-butyl-xanthate and nonyl sodium xanthogenate is 7 ~ 10:1 in the compound copper mine collecting agent.
The present invention is a composite collector; The stronger sodium n-butyl-xanthate of hydrophobic effect that the sulfide of copper in pair copper mine stone is not only arranged in the composite collector; Also have the nonyl sodium xanthogenate stronger to the oxide hydrophobic effect of copper in the copper mine stone, the present invention is that a spot of composition of sulfide of copper is that the copper mine stone flotation effect of oxide of copper is better to main a large amount of composition.
Below in conjunction with embodiment, the present invention is done explanation further.
