Abstract
A molybdenite floatation collector is characterized by comprising oil sludge and light diesel oil or kerosene in a weight ratio of 1:1-1:2. Compared with an existing technical scheme, the molybdenite floatation collector has the advantages that the problem of solid waste pollution is solved, product oil resources can be saved greatly, technical index of beneficiation is improved, production cost of enterprises is reduced, and enterprise benefit is improved. Utilization rate of the oil sludge is increased, waste utilization is realized, and pollution to the environment is reduced relatively.
Description
Technical field
The invention belongs to the flotation technology in non-ferrous metal, coal and nonmetal field, be specifically related to a kind of molybdenite flotation collecting agent.
Background technology
Flotation is a kind of effective ways that separate various fine fraction mineral by the difference of mineral surfaces physicochemical properties.Use floating agent can optionally change the mineral surface physicochemical properties, the flotation behavior of control ore is in order to obtain better sorting result.Can method for floating bring into play Expected Results, and the effect of floating agent is very crucial.Collecting agent is a most important class beneficiation reagent in the floating agent, and its effect is to make mineral surface hydrophobic, reduces the mineral surfaces wetability, thereby improves the floatability of mineral.At home and abroad in the flotation such as molybdenite, coal, graphite, hydrocarbon ils is to be employed as collecting agent always.The basic characteristics of hydrocarbon ils are: the hydrocarbon atom of whole molecule all is by covalent bonds, and chemism is very low, does not have an effect with the dipole hydrone, cashes out obvious hydrophobicity and slightly solubility.Hydrocarbon ils is with carbon chain growth, and the collecting performance also increases thereupon, and diffusing capacity reduces with carbon chain growth, and the reduction of diffusing capacity can affect again the collecting effect of hydrocarbon ils.Light diesel fuel and kerosene are widely used in molybdenite and coal, graphite flotation because carbochain is moderate always.Oil is non-renewable resources, and used light diesel fuel and kerosene all is product oil, and use amount is large, and beneficiation cost is always high.Along with the rise in price of international market product oil, the production cost of enterprise also can more come also high.In addition, the waste residue after use light diesel fuel and the kerosene ore dressing is also very serious to the pollution of environment, and manufacturing enterprise also will spend huge sums and administer, and this also is a key factor that reduces enterprise profit.Also have, the holding vessel at oil field gathering and transportation station or the crude oil storage tank of oil plant or semi-finished product holding vessel or product oil holding vessel and sewage from oil refinery are processed to precipitate in the slop tank that reclaims a large amount of greasy filth, oil content is about 30%～50% in these oily sludges, and a small amount of chemical agent that has a certain amount of silt and water and a small amount of breaking emulsion and dewatering to sneak into.Oil contained in the greasy filth is the mixture of clean petroleum product, heavy oil, crude oil, is hydrocarbon compound.These greasy filth generally are used as refuse and process, or buried or outwelled, and wherein contained oil content is wasted and does not say, goes back severe contamination and environment.
Summary of the invention
The object of the invention is to the problem that prior art exists is solved, provide a kind of and save light diesel fuel, kerosene and reduce the beneficiation reagent cost, and can improve again the novel molybdenite flotation agent of beneficiating technology index.
Technical solution of the present invention is:
This new collector is to be that 30%～50% greasy filth and light diesel fuel or kerosene consist of by oil content, and wherein the weight portion proportioning of greasy filth and light diesel fuel or kerosene is 1: 1～1: 2.
The good effect that the present invention produces is:
In technical solution of the present invention, the greasy filth that uses as collecting agent is processed the slop tank precipitation gained that reclaims as the crude oil storage tank of the holding vessel at oil field gathering and transportation station or oil plant or semi-finished product holding vessel or product oil holding vessel and sewage from oil refinery.Oil-containing is about 30%～50% in these oily sludges, and a small amount of chemical agent that has a certain amount of silt and water and a small amount of breaking emulsion and dewatering to sneak into.Oil contained in the greasy filth is the mixture of clean petroleum product, heavy oil, crude oil, is hydrocarbon compound.
This new collector is when the mineral such as flotation molybdenite, coal, graphite, and consumption is suitable with former collector dosage, and dosing place and dosing method all need not change.
The present invention compares with the prior art scheme, has not only solved the problem of solid waste pollution, and can significantly save the product oil resource, improves beneficiating technology index, reduces enterprise's production cost, improves the performance of enterprises.And improved the utilization rate of greasy filth, twice laid has reduced the pollution to environment relatively.
Collecting agent manufacture method of the present invention is very simple: greasy filth is added to stir in diesel oil, the kerosene in proportion get final product, or directly greasy filth is added by the flotation flowsheet chemical feeding points.
The specific embodiment
Below take as the collecting agent of molybdenite flotation as example.
Embodiment 1: adopt diesel oil as collecting agent and foaming agent in this example, greasy filth: diesel oil=1: 1 and 1: 2 compare as collecting agent and foaming agent, and dosing place, administration timing of drug, dosing condition are all carried out under the condition identical with former technique.
Embodiment 2: adopt diesel oil as collecting agent and foaming agent in this example, greasy filth compares as collecting agent and foaming agent, and dosing place, administration timing of drug, dosing condition are all carried out under the condition identical with former technique.
Listed JM-208 is foaming agent in the upper table.
We can see from embodiment, adopt collecting agent of the present invention than traditional collecting agent (other conditions are also identical) in the identical situation of consumption, select molybdenum recovery to be significantly improved, increase rate can reach 1.5 percentage points at least, mainly being light diesel fuel and kerosene reduces greatly as the consumption of collecting agent, can save a large amount of resources, reduce enterprise's production cost, increase economic efficiency.
The above only is preferred embodiments of the present invention, and is every according to the invention technical spirit, and any simple modification, change and equivalent structure that above example is made change, and all belong to protection domain of the present invention.Collecting agent of the present invention also can be used for coal separation, graphite or is used for the flotation of other non-ferrous metals as supplementary catching agent, also within protection domain of the present invention.
