Abstract
The present invention discloses a collecting agent for the flotation of collophanite, which is a collecting agent making the ore slurry of the collophanite processed through flotation at the normal temperature (14 DEG C). Tall oil is highly saponified to be extracted by an aromatic organic solvent. The aromatic organic solvent is removed; NaCl is added into mother liquid of which the aromatic organic solvent is removed to be coagulated, and then, filtering cloth is used for filtering and drying to prepare the collecting agent for the flotation of collophanite. The ore slurry can be floated at 14 DEG C, and thus, the energy is saved and the cost is reduced. The yield of ore concentrate by floating the collophanite is more than 50% and the recovery rate is more than 90%.
Description
The present invention relates to the preparation method of a kind of collophane normal temperature flotation with trapping agent, is that a kind of collophane ore pulp that makes carries out the preparation method that the trapping agent of usefulness is reclaimed in flotation under normal temperature (14 ℃).
The trapping agent that is used for Collophanite flotation has a variety of; in a lot of documents introduction is arranged all; for example US4511463 has introduced the trapping agent that contains dicarboxylic acids and saturated fatty alcohol; it is that N-acylamino-sodium n-caproate is made trapping agent that SU1115807 introduces what use in the method for floating, and SU1090448 introduces is a kind of by oxidation alkylidene di 2 ethylhexyl phosphonic acid, synthetic fatty acid and the trapping agent formed through the amino acid of acidylate.In the flotation of collophane, generally usefulness is that enuatrol, oxidation paraffin wax soap or vegetable oil add the trapping agent that the rosin saponification forms at present in China.These trapping agents generally must be heated to uniform temperature with ore pulp, need when for example using oxidation paraffin wax soap ore pulp is heated to 40 ℃.This ore pulp is heated to the method for uniform temperature, needs to consume a lot of energy, also need certain optional equipment be used for heating, this is one of high principal element of production cost.
The objective of the invention is to reduce cost, floatation process is carried out at normal temperatures, study a kind of preparation method of novel trapping agent for this reason for conserve energy.
The solution of the present invention is as follows: the preparation method is to be raw material with the tall oil, to use organic solvent extraction after the saponification of tall oil height, slough solvent, in sloughing the mother liquor of solvent, add NaCl and make it cohesion, filter the back drying and make and to carry out the trapping agent that flotation is used at normal temperatures through filter cloth.
Concrete steps are as follows:
1, in tall oil, adds N
2OH makes it the height saponification, and the addition of NaOH is the 15%-30%(W% of tall oil), during use NaOH is made into 10%(W%) the aqueous solution use.Add hot reflux, temperature is 80 ℃, adds 2%-10%(V% simultaneously) ethanol bubble when preventing saponification.Saponification time is 1-2 hour.
2, will the tall oil aqueous solution organic solvent extraction of height after the saponification, organic solvent can be chosen any one kind of them in benzene, toluene and ether, and the water that adds 1.5 times of saponification liquors during extraction dilutes it, simultaneously owing to can produce serious emulsion when extracting.Must add ethanol 5-25%(V%) to prevent emulsification.But continuous extraction, also graded extraction.
3, slough solvent.
4, in sloughing the mother liquor of solvent, add NaCl10-20%(W%), a large amount of brown thick liquids appears in cooling cohesion back.
5, the filter cloth with the 0.074mm aperture filters.
6, dry manufactured goods.
Technological process is:
Tall oil height the saponification (+NaOH aqueous solution, 80 ℃ add hot reflux) → with organic solvent (in benzene, toluene, the ether any) extraction (add ethanol and prevent emulsification) → slough solvent → in sloughing the mother liquor of solvent, add NaCl to make it cohesion → filtration (0.074mm aperture) → drying.
The used raw material of the present invention is from the masson pine papermaking wastewater, and cost is low, and the yield of trapping agent is more than 94% of tall oil, and trapping agent of the present invention can make floatation process can carry out in the time of 14 ℃.Need not heat ore pulp, save the energy, and the rate of recovery of concentrate is improved, reduce cost significantly.
Now, use result's contrast to be listed as follows when making trapping agent: (seeing Table 1) with existing oxidation paraffin wax soap with the trapping agent of the present invention's preparation
Embodiment 1:
Technical process as previously mentioned, organic solvent is selected toluene for use during extraction.
Embodiment 2:
Technical process as previously mentioned, organic solvent is selected benzene for use during extraction.
Embodiment 3:
Technical process as previously mentioned, organic solvent is selected ether for use during extraction, when using extracted with diethyl ether, does not produce emulsion, must not add ethanol.The use result of resulting product is as shown in table 1.
The present invention's (14 ℃ of temperature) oxidation paraffin wax soap (40 ℃ of temperature)
