Abstract
The present invention relates to a new oxided ore collector and its preparation method. It includes the following steps: phthalic imidine, hydroxylamine hydrochloride and water are mixed and stirred, and then NaOH is added in the above-mentioned mixture liquor so as to make the mixture liquor into basic liquor, the above-mentioned mixture liquor is stirred while heating to 70-80 deg.C, and after the raw materials are dissolved, the stirring operation is stopped. The above-mentioned mixture liquor is finally refluxed for 1.5-2.5h. at 78-80 deg.C, and cooled, so as to obtain reddish brown mixture liquor, which is the invented new type oxided-ore collector.
Description
The present invention relates to a kind of preparation method who is used for the organic trapping agent of ionic of oxide ore selective floation.
Be used as trapping agent that dressing rare-earth ore uses up to now nothing more than the hydroxamic acid trapping agent, China disclosed Chinese invention patent application CN86100710A about " a kind of synthesis technique of rare earth catching agent " on August 5th, 1987, and the collecting agent H205 that is synthesized also belongs to this example.The shortcoming of this class trapping agent is that it can not directly be dissolved in water, need add the ammoniacal liquor saponification during use, the dissolving of heating, and have niff.
Task of the present invention provides a kind of preparation method, can make a kind of collecting agent of oxidized ore of stating of topic in this way, i.e. JD collection agent, and this trapping agent can be dissolved in water at normal temperatures, and can directly be used in mineral floating.
The present invention adopts phthalimide and hydroxylamine to carry out chemical reaction, obtains inscribing a kind of collecting agent of oxidized ore of stating, and concrete steps comprise:
A, with phthalimide, hydroxyl hydrochloride, water blend and stir, wherein the mol ratio of phthalimide and hydroxyl hydrochloride is 1: 1-2;
B, adding NaOH aqueous solution neutralization in above-mentioned co-mixing system, making ph value of mixture then is 8-10:
C, above-mentioned mixed liquor are heated to 70-80 ℃ while stirring, treat to stop to stir after the dissolving of raw material thing, and in 78-80 ℃ of backflows 1.5-2.5 hours, cooling obtained the rufous mixed liquor then, and this mixed liquor is described a kind of collecting agent of oxidized ore.
This preparation method of the present invention, adopt marketable material phthalimide and hydroxyl hydrochloride under normal pressure, to react, step is simple and easy, products therefrom rufous mixed liquor can be used as the flotation that trapping agent is directly used in oxide ore, dissolved the separating of solid product that described rufous mixed liquor drying obtains in water, easy to use.
For the invention will be further described, below for an embodiment, wherein " part " is parts by weight:
With 147 parts of commercially available hydroxyl hydrochlorides and 250 parts of H
2O mixes, in stirring, in 15-60 minutes, add 147 parts of commercially available phthalimides, after treating that hydroxyl hydrochloride all dissolves, added the NaOH aqueous solution of 584 part of 10% weight concentration in stirring in 25-35 minutes, the pH value that makes mixed liquor is 9, continues to stir after 20 minutes heating mixed liquor to 80 ℃, treat that the raw material thing all stops to stir after the dissolving, in 80 ℃ of backflows 2 hours, cooling obtained the rufous mixed liquor then, and this mixed liquor is promptly inscribed a kind of collecting agent of oxidized ore of stating.
Aforesaid liquid shape trapping agent can be directly used in oxide ore flotation, also can drying becomes solid product and is applied to oxide ore flotation.
This preparation method of the present invention, a kind of collecting agent of oxidized ore of products obtained therefrom is tested through mineral floating, and it is as follows to the results are shown in table 1-table 3.
