Abstract
A method for floating copper sulfide ores relates to a method for floating copper sulfide ores. The method is characterized in that the beneficiation process adopts mercapto carboxylate as a collecting agent. The method has the characteristics of high selectivity to copper sulfide ores, small medicament dosage and flotation under a low pH value, and overcomes the defects of poor selectivity, large medicament dosage and environmental friendliness of the conventional method for flotation of copper sulfide ores by using the collecting agent. Provides an effective method for the flotation of copper sulfide minerals.
Description
Technical field
The method in a kind of floating cupric sulfide ore deposit relates to a kind of method for floating of copper-sulphide ores.
Background technology
In existing mining processing industry technology, the flotation of copper-sulphide ores mineral generally under alkali condition, adopt xanthate 、 ?medicine, thiourethane, xanthate etc. make collecting agent, make inhibitor with lime and adjust agent with pH.General slurry pH is between 8.5-11, and the consumption of collecting agent is between 10-100g/t.
The shortcoming of above-mentioned prior art is: in the existing conventional dose xanthate 、 ?selectivity such as medicine relatively poor relatively; Consumption is also bigger; In addition environment is had certain harmfulness, and selectivity preferably ester class medicament also have price more expensive with the building-up process complicacy wait some limitation.
Summary of the invention
The object of the invention is exactly the deficiency that exists to above-mentioned prior art, provides a kind of selectivity high, and dosing is few, the method in the floating cupric sulfide ore deposit that flotation effect is good.
The objective of the invention is to realize through following technical scheme.
The method in a kind of floating cupric sulfide ore deposit is characterized in that its ore dressing process adopts mercapto-carboxylic ester as collecting agent.
The method in a kind of floating cupric sulfide of the present invention ore deposit, the ester group that it is characterized in that described collecting agent mercapto-carboxylic ester are the group of carbon 2-carbon 8.
The method in a kind of floating cupric sulfide of the present invention ore deposit, the mercaptan carboxylic acid's group that it is characterized in that described collecting agent mercapto-carboxylic ester are the group of carbon 2-carbon 3.
The method in a kind of floating cupric sulfide of the present invention ore deposit, the pH that it is characterized in that described ore dressing process is 7-12.
The method in a kind of floating cupric sulfide of the present invention ore deposit, the consumption that it is characterized in that described ore dressing process collecting agent mercapto-carboxylic ester are that 10-100g/t does the ore deposit.
The method for floating of a kind of copper-sulphide ores of the present invention uses mercapto-carboxylic ester to make collecting agent.When the floating cupric sulfide ore deposit; At room temperature carry out flotation; In copper grade is the ore pulp of 0.55-0.65%, add pH adjustment agent, collecting agent, foaming agent respectively successively and stir, can obtain to contain Cu3.5%-7.2%, the copper-sulphide ores rough concentrate of rate of recovery 74%-89% through one roughing.The method in this floating cupric sulfide ore deposit has copper sulfide mineral high selectivity and dosing are reached the low pH value characteristics of flotation down less, has overcome conventional collecting agent, like xanthate, and poor selectivity, big, the with serious pollution shortcoming of dosing.For the copper sulfide mineral flotation provides a kind of effective ways.
The specific embodiment
The method in a kind of floating cupric sulfide ore deposit adopts mercapto-carboxylic ester as collecting agent in its floatation process; The collecting agent mercapto-carboxylic ester is one big type, and concrete medicament has ethyl thioglycolate, isooctyl thioglycolate, the different monooctyl ester of mercaptopropionic acid.Collecting agent is generally oily liquids, is slightly soluble in the water.
Specifically comprising step is:
At first, raw ore is carried out ore grinding, the ore pulp that mill is good adds flotation cell, regulates slurry pH to desired value, adds collecting agent then, also can add foaming agent, and stir flotation, obtains the copper sulfide rough concentrate.
In the rougher process; The slurry pH conditioning agent can (like lime) add when ore grinding, also can add the adjustment agent (like NaOH, potassium hydroxide, sodium carbonate, ammonium hydroxide etc.) beyond the lime together, and mixing time is about 2-3 minute; Add collecting agent (writing concrete title and consumption) then; Add foaming agent (writing concrete title and consumption) after a while, mixing time is about 2-3 minute, carries out ore dressing process.
Embodiment 1
A kind of chalcopyrite, pyrite etc. of containing mainly contain and use metalliferous mineral, and the ore of gangue mineral such as quartz, cupric 0.61%; Raw ore behind the ore grinding, adds flotation cell through muck; Regulate slurry pH (lime can add in the ball mill when using lime) to 8.5 with pH value adjustment agent then, pulp density 35% is done the ore deposit with collecting agent ethyl thioglycolate 28g/t again and is added ore pulp; Stirred 2 minutes, and, can obtain the copper sulfide rough concentrate through one roughing.
Copper-sulphide ores contrast test index is seen table 1.
Table 1 the present invention makes with medicament and the mineral processing index contrast of using Z-200
Embodiment 2
A kind of chalcopyrite, pyrite etc. of containing mainly contain and use metalliferous mineral, and the ore of gangue mineral such as quartz, cupric 0.57%; Raw ore behind the ore grinding, adds flotation cell through muck; Regulate slurry pH (lime can add in the ball mill when using lime) to 7.5 with pH value adjustment agent then, pulp density 35% is done the ore deposit with collecting agent ethyl thioglycolate 28g/t again and is added ore pulp; Stirred 2 minutes, and, can obtain the copper sulfide rough concentrate through one roughing.
Copper-sulphide ores contrast test index is seen table 2.
Table 2 the present invention makes with medicament and the mineral processing index contrast of using Z-200
Embodiment 3
A kind of chalcopyrite, pyrite etc. of containing mainly contain and use metalliferous mineral, and the ore of gangue mineral such as quartz, cupric 0.59%; Raw ore behind the ore grinding, adds flotation cell through muck; Regulate slurry pH (lime can add in the ball mill when using lime) to 9.5 with pH value adjustment agent then, pulp density 35% is done the ore deposit with collecting agent ethyl thioglycolate 15g/t again and is added ore pulp; Stirred 2 minutes, and, can obtain the copper sulfide rough concentrate through one roughing.
Copper-sulphide ores contrast test index is seen table 3.
