Abstract
This disclosure provides a method for promoting copper oxide mineral flotation using an
amino acid, comprising. An amino acid as activator is added to a sulphidized copper oxide ore
pulp, and the sulphidized copper oxide ore pulp is subjected to flotation in a flotation machine
with xanthate as a collector. Based on the sulfidation flotation of the copper oxide mineral, the
method improves the flotation efficiency of the copper oxide mineral by adding an amino acid
during the flotation. The copper oxide mineral is crushed and sieved, and then the amino acid,
sulfide and related flotation agents are added to a flotation machine to carry out the flotation
within controlled time. Compared with the flotation without the addition of amino acids, the
flotation recovery rate of the copper oxide mineral is increased by up to 10%. Obviously, the
amino acid promotes the sulphidizing flotation of the copper oxide mineral. The method
disclosed herein provides a way for the industrial flotation of copper oxide minerals.
Description
This application relates to beneficiation of copper oxide ores, and more particularly to a
method for promoting sulphidizing flotation of a copper oxide ore using an amino acid.
Copper oxide mineral and mixed copper mineral account for 10%-15% of the worldwide
copper reserves. In China, the copper oxide mineral accounts for a quarter of the copper
reserves. Oxidation zones and huge copper oxide deposits are distributed on most of copper
sulfide deposits. The efficient exploitation and utilization of copper oxide mineral has become a
research highlight. The copper oxide mineral is dominated by malachite, azurite, cuprite and
chrysocolla. Industrially, the copper oxide minerals are usually floated by the sulfidation
xanthate method. Sodium sulfide is often employed as a sulphidizing agent in the sulfidation of
the copper oxide mineral. Specifically, it can combine with the copper ions on the surface of the
copper oxide mineral to form a copper sulfide film attaching to the mineral surface, improving
the hydrophobicity of the mineral surface to increase the adsorption rate of the collector and
promoting the formation of dixanthogen in the adsorption layer. In addition, it has been found
'0 that in addition to the sulfide, activating agents can also greatly improve the flotation efficiency
of copper oxide minerals. Ammonium sulfate and ethylenediamine phosphate are two
widely-used activating agents, where ammonium sulfate can effectively weaken the inhibitory
effect of sodium sulfide, and its synergy with ethylenediamine can effectively improve the
quality and recovery of mineral. These activating agents form insoluble sulfides with the copper
ions on the surface of the mineral to increase the hydrophobicity of the mineral, and allow the
mineral surface to be continuously dissolved. However, the addition amount of the sulfide,
ammonium sulfate and ammonium organics is relatively high in the industrial flotation, and the
flotation wastewater is difficult to treat and may pollute the ecological environment. Therefore,
it is of great industrial significance to develop an efficient and environmentally-friendly
activating agent.
Amino acid is an environment-friendly reagent, and has good compatibility with the ecological environment. The amino acids all have a carboxyl group and an amino group, and vary in the R group. The amino group may play a similar role as ethylenediamine phosphate to promote the sulfidation flotation of copper oxide minerals, and the carboxyl group can theoretically bind the copper ions on the surface of the sulphidized mineral. The R groups of some hydrophobic amino acids have a long carbon chain and a benzene ring, which may improve the hydrophobicity of copper oxide minerals in the flotation. In view of the above, an amino acid-based floatation method of copper oxide ores is designed herein, which can significantly enhance the floatation of copper oxide ores without causing environmental pollution.
An objective of the present disclosure is to provide a method for promoting sulphidizing
flotation of a copper oxide ore using an amino acid, which can improve the flotation recovery
rate of the copper oxide minerals at a relatively low consumption of amino acid. This
application provides a new approach for the selection of flotation reagents.
The technical solutions of the present disclosure are described as follows.
A method for promoting copper oxide mineral flotation using an amino acid, comprising:
subjecting a copper oxide ore pulp to sulphidization to obtain a sulphidized copper oxide
ore pulp; and
adding a solution of the amino acid as activator to the sulphidized copper oxide ore pulp
for reaction followed by flotation in a flotation machine in the presence of xanthate, wherein the
xanthate is used as a collector.
In some embodiments,
the copper oxide pulp is prepared through steps of:
(1) grinding a copper oxide ore to obtain a ground copper oxide mineral with a particle
size of 0.074 mm; and sieving the ground copper oxide mineral to obtain a 200-mesh copper
oxide mineral powder; and
(2) adding the copper oxide mineral powder and water to a flotation tank followed by
uniform stirring to obtain the copper oxide ore pulp with a concentration of 200-400 g/L.
In some embodiments, the sulphidization is carried out by adding 500-3500 g/t of sodium
sulfide to the copper oxide ore pulp; preferably, an addition amount of the sodium sulfide is
3000 g/t; 50-800 g/t of the amino acid is added to the sulphidized copper oxide ore pulp; preferably, an addition amount of the amino acid is 100 g/t; and the reaction is performed for 2-5 min; preferably, 3 min. In some embodiments, the flotation is performed through steps of: adding 50-300 g/t of butyl xanthate to the sulphidized copper oxide ore pulp for collection; adding 10-50 g/t of terpenic oil as a foaming agent to collect a floated copper oxide mineral; and subjecting the collected copper oxide mineral to filtration and drying; preferably, 200 g/t of the butyl xanthate is added to the sulphidized copper oxide pulp; and 10 g/t of the terpenic oil is added. In some embodiments, the amino acid is hydrophobic; preferably, the amino acid hydrophobic is phenylalanine or lysine. The beneficial effects of the present disclosure are described as follows. Based on the characteristics of the sulphidizing flotation of the copper oxide minerals, the present disclosure introduces an amino acid to improve the flotation efficiency. The copper oxide mineral is crushed and sieved, and then the amino acid, a sulfide and related flotation agents are added to a flotation machine to carry out the flotation within controlled time. Compared with the flotation without the addition of amino acids, the flotation recovery rate of the copper oxide mineral is increased by at most 10%. Obviously, the amino acid significantly promotes the sulphidizing flotation of copper oxide minerals. The method disclosed herein provides a way for the industrial flotation of copper oxide minerals.
