Description
Technical field
The present invention relates to iron ore dressing flotation technology field, particularly a kind of high grade iron mineral floating collecting agent.
Background technology
Floatation is one of effective beneficiation method of iron ore.From nineteen fifties, the iron ore flotation method is used widely in China.But, the floatation of iron mineral collecting agent collecting ability of application a little less than, beneficiating efficiency is relatively low.Later 1990s, iron ore reverse flotation process has successfully been studied by China, and beneficiating efficiency is higher.But its medicament itself exists kind many, the preparation complicated problems.The high grade iron mineral floating collecting agent prescription of this proposition; High few the iron ore reverse flotation process beneficiating efficiency with positive floatation of iron ore technology medicament kind; Preparing simple advantage and unite, is the particularly prescription of high grade iron ore scientific and efficient of our iron ore.
Summary of the invention
The object of the invention provides a kind of high grade iron mineral floating collecting agent, provides high grade iron mineral floating beneficiating efficiency height, few, the simple floatation of iron mineral prescription of preparation of use medicament kind.
The objective of the invention is to realize through following technical proposals:
High grade iron mineral floating collecting agent of the present invention is characterized in that being made up of α hydroxyl-aliphatic acid and beta-hydroxy fatty acid, and the percentage by weight of each component is:
| The following carbochain α hydroxyl-aliphatic acid of α hydroxyl-12 | 1～3% |
| α hydroxyl-ten difatty acid | 1～5%? |
| α hydroxyl-ten tri-fatty | 1～5% |
| More than the percentage by weight sum of three kinds of components | 4～6% |
| The following aliphatic acid of β hydroxyl-12 | 0～5% |
| β hydroxyl-ten difatty acid | 5～16% |
| β hydroxyl-ten tri-fatty | 5～16% |
| More than the percentage by weight sum of three kinds of components | 14～16% |
| α hydroxyl-17 aliphatic acid | 0～6% |
| α hydroxyl-18 aliphatic acid | 0～6% |
| 18 above carbochain α hydroxyl-aliphatic acid | 0～4% |
| More than the percentage by weight sum of three kinds of components | 4～6% |
| β hydroxyl-17 aliphatic acid | 0～5% |
| β hydroxyl-18 aliphatic acid | 5～16% |
| 18 above carbochain β carbochain hydroxyl-aliphatic acid | 0～6% |
| More than the percentage by weight sum of three kinds of components | 14～16% |
| α hydroxyl-14 aliphatic acid | 5～21% |
| α hydroxyl-15 aliphatic acid | 5～21% |
| α hydroxyl-16 aliphatic acid | 5～21% |
| More than the percentage by weight sum of three kinds of components | 19～21% |

| β hydroxyl-16 aliphatic acid | 0～41% |
| More than the percentage by weight sum of three kinds of components | 39～41% |
α hydroxyl-aliphatic acid and beta-hydroxy fatty acid content account for total content proportion and are not less than 99%; α hydroxyl-the aliphatic acid of 12 to 18 carbon atoms and beta-hydroxy fatty acid content account for whole α hydroxyl-aliphatic acid and the beta-hydroxy fatty acid content ratio is not less than 95.5%.
α hydroxyl-aliphatic acid and β hydroxyl-aliphatic acid can increase the collecting effect through hydroxyl and conjugation that the carboxylic acid group forms in to the iron ore collecting, its mechanism of action is distinguished as follows:
Iron mineral contains Fe
3+, Fe
3+Strong effect with hydrone can cause the obvious deflection of hydrone cloud density, makes H in the hydrone
+Exposed, thus the cloud density between the O-H key in the hydrone weakened, make hydrone very easily lose H
+Fe
3+Its hydrolytic process is: (1) at first cooperates with hydrone; (2) progressively carry out the fractional hydrolysis reaction.
Fe
3+Except above-mentioned hydrolysis, also possibly produce the multinuclear hydrated complexes of polymerization.
After iron mineral was accomplished said hydrolyzed, α-carboxylic acid soap, β-carboxylic acid soap of can be respectively in water, forming with α hydroxyl-aliphatic acid and β hydroxyl-aliphatic acid took place to act on as follows:
（1）
（2）
（3）
The beta-hydroxy acid soap
（1）
（2）
（3）
The invention has the beneficial effects as follows:
This collectors application is 9.2-9.7 in high grade iron mineral direct flotation at PH, collector dosage 290 gram/tons-360 gram/ton, and when pulp density was 30%-40%, its ore dressing effect was all more satisfactory.If ore pulp PH is 9.5, collector dosage 330 gram/tons are when pulp density is 35% left and right sides; Its ore dressing effect can obtain concentrate grade more than 66.5% with even more ideal, the beneficiating technology index of operation recovery more than 85%; Compare with the general collecting agent of present application; Under the close situation of concentrate grade, operation recovery can improve 13%-17%, and effect is obvious.
