Abstract
The invention discloses a molybdenite flotation collector which is mixed by butyl oleate and diesel oil; and the volume content of the butyl oleate in the collector is 10 % to 20 %. The collector disclosed by the invention has a simple manufacturing method and is easy to operate; both the application and use level of the collector are equivalent to those of a traditional diesel oil collector; moreover, the price is also equivalent; the collector is adopted for performing the flotation of the molybdenite according to a conventional method; and thus the molybdenum recovery rate can be obviously increased.
Description
Technical field
The invention belongs to the mineral floating technical field, be specifically related to a kind of molybdenite flotation collecting agent.
Background technology
Flotation be utilize mineral surfaces hydrophobic-the hydrophily difference, a kind of method that mineral are processed.Though utilize the natural hydrophobicity of mineral, can carry out sorting of ore, use floating agent can change the hydrophobicity of ore, so that control the flotation behavior of ore, obtain better sorting result.Therefore, the performance of floatation process effect and floating agent relation is very close.
Collecting agent is a most important beneficiation reagent in the floatation process.At home and abroad hydrocarbon ils is always as collectors application in the molybdenite flotation technology, and particularly diesel oil and kerosene are most widely used, and for up to a century.Hydrocarbon ils selects molybdenum to have following characteristics: increase with carbochain, collecting ability is more and more stronger, and diffusing capacity then increases with the hydrocarbon ils carbon chain lengths and reduces, and the reduction of diffusing capacity can influence the collecting ability of hydrocarbon ils again.Diesel oil and kerosene are moderate because of its chain length, and are widely used in molybdenite flotation collecting agent.
Molybdenite is a kind of non-renewable resources, improves the molybdenum recovery that selects of molybdenite, and this scarce resource meaning is extremely great for making full use of and protecting.It is the difficult problem selecting molybdenum circle to receive much attention and be badly in need of solving that molybdenum recovery is selected in raising always.For a long time, this technical field fails to search out effective collecting agent that molybdenum recovery is selected in raising.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned the deficiencies in the prior art, a kind of molybdenite flotation collecting agent is provided, this collecting agent manufacture method is simple, easy to operate, suitable with traditional diesel oil collector dosage, price is also suitable, adopts this collecting agent to carry out Floatation of Molybdenite according to conventional method, and molybdenum recovery is improved significantly.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of molybdenite flotation collecting agent, it is characterized in that this collecting agent is mixed by butyl oleate and diesel oil, and the volumn concentration of butyl oleate is 10%～20% in the described collecting agent.
Above-mentioned a kind of molybdenite flotation collecting agent, described diesel oil are light diesel fuel.
The manufacture method of collecting agent of the present invention is: butyl oleate is added in the diesel oil in proportion, and stirring gets final product.
The present invention compared with prior art has the following advantages: the manufacture method of collecting agent of the present invention is simple, easy to operate, the usage of this collecting agent and consumption are all suitable with the conventional diesel collecting agent, price is also suitable, adopt this collecting agent to carry out Floatation of Molybdenite according to conventional method, molybdenum recovery is improved significantly.
Below by embodiment, technical scheme of the present invention is described in further detail.
The specific embodiment
Embodiment 1
A kind of molybdenite flotation collecting agent of present embodiment is mixed by butyl oleate and light diesel fuel, and the volumn concentration of butyl oleate is 10% in the collecting agent.
Embodiment 2
A kind of molybdenite flotation collecting agent of present embodiment is mixed by butyl oleate and light diesel fuel, and the volumn concentration of butyl oleate is 20% in the collecting agent.
Embodiment 3
A kind of molybdenite flotation collecting agent of present embodiment is mixed by butyl oleate and light diesel fuel, and the volumn concentration of butyl oleate is 15% in the collecting agent.
Collecting agent of the present invention and conventional diesel collecting agent performance compare:
Adopt the collecting agent of conventional diesel collecting agent and embodiment 1 to 3 respectively, carry out Floatation of Molybdenite according to conventional method, the consumption of collecting agent is 100g/t (molybdenite per ton adds the 100g collecting agent), JM-208 is a foaming agent, consumption is 80g/t (molybdenite per ton adds the 80g foaming agent), and flotation results sees the following form.
The different collecting agent flotation of table 1 molybdenite comparative test result
Wherein, grade is the quality percentage composition of molybdenum in every work-in-process;
As can be seen from Table 1, adopt collecting agent of the present invention to carry out Floatation of Molybdenite, the molybdenum grade generally increases in each work-in-process.Compare with the conventional diesel collecting agent, adopt collecting agent of the present invention to carry out Floatation of Molybdenite, the quality of molybdenum is below 10.04% of molybdenum gross mass in the raw ore in the true tailings, illustrate that the molybdenum more than 89.96% has obtained recovery in the raw ore, molybdenum recovery obviously improves, and maximum increase rate reaches 2.93 percentage points.
The above; it only is preferred embodiment of the present invention; be not that the present invention is done any restriction, everyly any simple modification that above embodiment did, change and equivalent structure changed, all still belong in the protection domain of technical solution of the present invention according to the invention technical spirit.
Claims (2)
