Problems solved by technology

[0002] Ilmenite is an oxide mineral of iron and titanium. Flotation and refinement of ilmenite is an important way to improve resource utilization. The general flotation agents are fatty acid collectors, phosphorus collectors, and arsenic collectors. Collectors, hydroxamic acid collectors, etc. Among these collectors, especially arsenic collectors contain toxic heavy metal components, which are likely to cause environmental pollution, and at the same time, the production process is complicated and the amount of use is large.

preparation example Construction

[0017] A kind of preparation method of mineral flotation collector, heating oleic acid and oxidized paraffin wax soap and adding lye to stir, saponification, then adding emulsifier and stirring evenly, finally adding C 7-9 Hydroxamic acid, polyethylene glycol octylphenyl ether and citric acid are added and stirred evenly to obtain a mineral flotation collector; the raw material components are as follows in parts by weight: 0.30-0.70 parts of oleic acid, 0.20-0.20 parts of oxidized paraffin wax soap 0.40 parts, emulsifier 0.02-0.08 parts, C 7-9 0.10-0.20 parts of hydroxamic acid, 0.05-0.10 parts of polyethylene glycol octylphenyl ether, and 0.05-0.12 parts of citric acid.

[0018] Further, 0.40 part of oleic acid, 0.25 part of oxidized paraffin wax soap, 0.02 part of emulsifier, C 7-9 0.15 parts of hydroxamic acid, 0.08 parts of polyethylene glycol octylphenyl ether, and 0.1 parts of citric acid.

[0019] The emulsifier is OP emulsifier or TX emulsifier.

[0020] The lye is ...

Embodiment 1

[0023] The components are calculated in parts by weight: heat 0.30 parts of oleic acid and 0.20 parts of oxidized paraffin wax soap and add NaOH solution to stir and complete saponification. The heating temperature of the system is 100°C, and the saponification heating time is 4 hours. Then add 0.02 part of OP emulsifier and stir for 1 hour to mix evenly, and finally add 0.10 part of C 7-9 Hydroxamic acid, 0.05 part of polyethylene glycol octyl phenyl ether and 0.05 part of citric acid were added and stirred for 40 minutes and mixed uniformly to prepare a mineral flotation collector.

[0024] Using the prepared mineral flotation collector, the raw ore with a positive flotation grade of 20.12% can be used to obtain a titanium concentrate grade of 52.32%, and the recovery rate is a good indicator of 85.12%.

Embodiment 2

[0026] The components are calculated in parts by weight: heat 0.50 parts of oleic acid and 0.30 parts of oxidized paraffin wax soap and add KOH solution to stir and complete saponification. The heating temperature of the system is 110°C, and the saponification heating time is 3 hours. Then add 0.05 parts of TX emulsifier and stir for 1 hour to mix evenly, and finally add 0.15 parts of C 7-9 Hydroxamic acid, 0.08 part of polyethylene glycol octyl phenyl ether and 0.10 part of citric acid were added and stirred for 40 minutes and mixed evenly to prepare a mineral flotation collector.

[0027] Using the prepared mineral flotation collector, the raw ore with a positive flotation grade of 20.12% can obtain a titanium concentrate grade of 53.03%, and the recovery rate is a good indicator of 84.87%.

Abstract

The invention discloses a mineral floatation colleting agent, and especially discloses a mineral floatation colleting agent and a manufacturing method thereof, and belongs to the technical field of floatation colleting agents. The raw materials comprise the following components in the following parts by weight: 0.30-0.70 parts of oleic acid, 0.20-0.40 parts of oxidized paraffinum sodium salt, 0.02-0.08 parts of emulgator, 0.10-0.20 parts of C7-9 hydroximic acid, 0.05-0.10 parts of polyethylene glycol octylphenol ether, and 0.05-0.12 parts of citric acid. The colleting agent is manufactured by the following method: heating the oleic acid and the oxidized paraffinum sodium salt, and adding an alkali liquor, mixing, saponifying, and adding the emulgator and mixing uniformly, and finally adding the C7-9 hydroximic acid, the polyethylene glycol octylphenol ether, and the citric acid, and mixing uniformly to form the colleting agent. The colleting agent is advantaged by environmental-friendly and low cost while effectively ensuring mineral separation effect of ilmenite floatation collection. After coordination of each component, concentration grade of the ilmenite can be effectively improved, and use amount of sulfuric acid in the floatation is effectively reduced.
