Problems solved by technology

However, for a long time, the direct flotation process of phosphate rock needs to heat the pulp to ensure the dispersion of the collector to obtain the ideal separation index. How to find a suitable collector from the aspects of energy saving and cost reduction is also a reality. question

Embodiment 1

[0028] Each component is calculated in parts by weight: after heating 0.15 parts of ricinoleic acid to 90° C., adding a concentration of 30% NaOH solution, the amount of ricinoleic acid, octadecenoic acid and citric acid in subsequent steps can be Complete saponification is appropriate; then add 0.5 parts of cis-9-octadecenoic acid and 0.05 parts of citric acid, stir and mix and heat to melt and saponify, saponification time is 2 hours; after saponification is completed, add 4-ethyl-6- Propyl nonanol (C14 higher alcohol) higher alcohol 0.3 parts, prepared normal temperature phosphate rock flotation collector.

[0029] Using phosphate rock collector, flotation in a neutral environment at 10°C, positive flotation P 2 o 5 Phosphate rock with a grade of 21.25% and low grade can obtain phosphorous concentrate P 2 o 5 The grade is 32.12%, and the recovery rate is 85.02%, which is a good indicator.

Embodiment 2

[0031] The components are calculated in parts by weight: after heating 0.18 parts of ricinoleic acid to 100°C, adding a concentration of 35% KOH solution, the amount of which can be obtained in subsequent steps by ricinoleic acid, octadecenoic acid and citric acid It is advisable to completely saponify; then add 0.55 parts of trans-9-octadecenoic acid and 0.08 parts of citric acid, stir and mix and heat to melt and saponify. The saponification time is 2.5 hours; after saponification is completed, add 3-diethyl-5 - 0.19 parts of propyl heptanol (C15 higher alcohol) to prepare a normal temperature phosphate rock flotation collector.

[0032] Using this new type of phosphate rock collector, flotation in a neutral environment at 25°C, positive flotation of P 2 o 5 Phosphate rock with a grade of 21.25% and low grade can obtain phosphorous concentrate P 2 o 5 The grade is 32.55%, and the recovery rate is 85.10%, which is a good indicator.

Embodiment 3

[0034] Each component is calculated in parts by weight: after heating 0.2 parts of ricinoleic acid to 110° C., adding a concentration of 40% NaOH solution, the amount of ricinoleic acid, octadecenoic acid and citric acid in subsequent steps can be Complete saponification is appropriate; then add 0.6 parts of octadec-6-enoic acid and 0.1 parts of citric acid, stir and mix and heat to melt and saponify, saponification time is 3 hours; after saponification is completed, add 2,4-tetramethyl- 0.1 part of 5-diethyl octanol (C16 higher alcohol) was used to prepare a normal temperature phosphate rock flotation collector; the octadecenoic acid used came from waste oil extraction.

[0035] Using this new type of phosphate rock collector, flotation in a neutral environment at 35°C, positive flotation of P 2 o 5 Phosphate rock with a grade of 21.25% and low grade can obtain phosphorous concentrate P 2 o 5 The grade is 33.68%, and the recovery rate is 85.22%, which is a good indicator. ...

Abstract

The invention discloses normal-temperature phosphorite flotation collector and a preparation method thereof and belongs to the technical field of phosphorite flotation collector. The collector is made from, by weight, 0.50-0.60 part of octadecenoic acid, 0.15-0.20 part of ricinoleic acid, 0.05-0.10 part of citric acid, and 0.10-0.30 part of higher alcohol of the level above C12. The preparation method of the collector includes: heating the ricinoleic acid, adding alkali liquor, mixing well, adding the octadecenoic acid and the citric acid, mixing, heating for melting and saponification, adding the higher alcohol, and mixing well to obtain the normal-temperature phosphorite flotation collector. The cost of the normal-temperature phosphorite flotation collector is low, the materials of the normal-temperature phosphorite flotation collector are widely sourced, and recovery of illegal cooking oil can be promoted. The preparation method has the advantages that efficient normal-temperature phosphorite flotation can be achieved, beneficiation cost is reduced, and flotation froth is good and non-sticky and weak in capacity of collecting carbonate.

Description

technical field [0001] The invention relates to an ore foam flotation collector, in particular to a normal temperature phosphate rock flotation collector and a preparation method thereof. Background technique [0002] There are many types of collectors for phosphate rock, and it is difficult to use a boundary to divide them. With the emergence of new practical problems, more and more new collectors have emerged. [0003] In the development of phosphate rock flotation collectors, it is not difficult to see that the research and development of new collectors are based on the modification of existing collector molecules, the evaluation of the flotation effect of existing collectors, and solving some practical problems. Based on the principles of learning from each other, complementary advantages and grafting advantages, we design and develop efficient, multifunctional and highly selective flotation collectors. However, for a long time, the direct flotation process of phosphate...
