(3) There are many difficult ores and few easy ores
Reagents belong to organic insoluble substances, and the dissolving effect in the pulp is not good. They are in the form of micelles in the pulp at low temperature (<15°C), and there are few free forms. The dosage of the reagents is large, and the flotation effect is poor.
In addition, the consumption of soda ash is large, the foam viscosity is high, it is not easy to defoam, the concentrate is difficult to settle, and the flotation takes a long time

Embodiment 1
[0024] Add 60 parts of oxidized paraffin wax soap, 40 parts of oleic acid, 60 parts of diesel oil, 6 parts of Tween-80, and 4 parts of sodium lauryl sulfate into 120 parts of water, heat to 50 ° C, and stir at a speed of 300 rad / min Mix evenly to obtain the medium and low temperature combination collector for phosphate rock.
[0025] Normal temperature flotation test sample The ore sample was collected from a phosphate mine in Chaoyang, Liaoning. The raw ore P 2 O 5 2.20%, the pulp temperature is 13°C, no heating is required, and the phosphorous concentrate can be obtained after one roughing and one beneficiation direct flotation, concentrate P 2 O 5 It was 33.42%, and the recovery rate was 75.39%.
Embodiment 2
[0027] Add 80 parts of oxidized paraffin wax soap, 20 parts of oleic acid, 50 parts of diesel oil, 6 parts of Tween-80, and 6 parts of sodium lauryl sulfate into 130 parts of water, heat to 40 ° C, and stir at a speed of 500 rad / min Mix evenly to obtain the medium and low temperature combination collector for phosphate rock.
[0028] Normal temperature flotation test sample The ore sample was collected from a phosphate mine in Yunnan, and the raw ore P 2 O 5 It is 2.52%, without heating, after a rough selection and a selected direct flotation, the P-containing 2 O 5 It is 31.88%, and the recovery rate is 88.81% phosphorus concentrate.
Embodiment 3
[0030] Add 100 parts of oxidized paraffin wax soap, 70 parts of kerosene, 5 parts of Tween-80, and 6 parts of sodium dodecylbenzenesulfonate into 140 parts of water, heat to 70 ° C, and stir and mix evenly at a speed of 400 rad / min. That is, the medium and low temperature combination collector of phosphate rock is obtained.
[0031] Normal temperature flotation test sample The ore sample was collected from a phosphate mine in the north, and the original ore contained P 2 O 5 It is 5.12%, without heating, after one rough, one sweep and two fine selection, the closed circuit test obtained the content of P 2 O 5 The grade is 38.12%, and the recovery rate is 89.45% phosphorus concentrate.

Abstract
Disclosed are a composite collector for low-and-medium-temperature phosphate flotation and a preparation method thereof. The composite collector is composed of 100 parts of carboxylic acid collector, 50-100 parts of hydrocarbon type oil, 1-10 parts of non-ionic surface active agent, 1-10 parts of anionic surface active agent and 80-200 parts of water, wherein the carboxylic acid collector serves as the main collector, the hydrocarbon type oil serves as the auxiliary collector, the non-ionic surface active agent serves as the synergist, and the anionic surface active agent serves as the emulsifier. The preparation method includes steps of uniformly mixing and stirring the components according to the proportion in the speed of 300-1500rad/min at the temperature ranging from 40DEG C to 80 DEG C to obtain the composite collector for low-and-medium temperature phosphate flotation. When in use of the composite collector, the composite collector is added into a pulp mixing barrel to be mixed with pulp sufficiently according to dosage directly, so that floatation can be carried out in a floatation trough at the normal temperature and the operation of heating to pulp is omitted. The composite collector has the advantages that better low-and-medium-temperature flotation effect can be achieved, bubbles generated by the composite collector are favorable for concentrate deposition, the chemical agent usage is small, raw materials for the composite collector are wide in sources, and the composite collector is moderate in price.
Description
Technical field [0001] The present invention involves a mineral selection agent and its preparation method, especially the medium -low temperature phosphate combination collection collection and its preparation method. The medium -medium low -temperature phosphorus mines combined with a lotion is emulsion, which is easy to prepare and process.The low -temperature flotation performance is stable, the raw materials are wide, the price is low, and it is easy to promote. Background technique [0002] my country's phosphorus ore resources are abundant, phosphorus data reserves are second in the world. The characteristics of phosphate resources in my country are: (1) rich resources, but the distribution is too concentrated. The total reserves are more than 80 % or more. Hubei and Hunan in the south.(2) There are more and low -quality phosphate ore and less rich ore.The average quality of phosphate ore in the country is only 16.95%.(3) Difficult minerals and less ore selection.85%of the...
