Problems solved by technology

Anionic collectors are mostly fatty acids and soap collectors. When used in flotation pulp at low temperature, there are problems such as poor low temperature resistance and weak foaming performance, resulting in a decline in collection performance.
Since most of the spodumene mines in my country are located in high-altitude or severe cold areas, and the temperature is low in autumn and winter, the collectors currently used in production have poor adaptability to low temperature, which seriously affects the selection index

preparation example Construction

[0029] In the second aspect, the present invention provides a method for preparing a spodumene ore flotation collector, comprising the following steps: uniformly mixing vegetable oleic acid and dodecyldimethyl tertiary amine to obtain a mixed material, and said The mixed material is mixed with sodium hydroxide, heated and stirred until the reaction is complete, and the spodumene ore flotation collector is obtained;

[0030] Wherein, the consumption of described raw material is counted as in parts by mass:

[0031]

[0032] Preferably, the vegetable oleic acid is soybean oleic acid, and the iodine value of the soybean oleic acid is 120-140.

[0033] Preferably, the heating and stirring conditions include: the temperature is 50-65° C., and the time is 10-30 minutes. The temperature of heating and stirring can be 50°C, 55°C, 60°C, 65°C, or any value between the above two values; the time of heating and stirring can be 10min, 15min, 20min, 25min, 30min, or the above two values...

Embodiment 1

[0042] Mix 320g soybean oleic acid and 21g dodecyl dimethyl tertiary amine evenly to obtain a mixed material, mix the mixed material with 53g sodium hydroxide, and stir for 20min at a temperature of 60°C under normal pressure to make it After complete reaction, a translucent light yellow paste is obtained, which is the spodumene ore flotation collector.

Embodiment 2

[0044] Mix 150g soybean oleic acid and 10g dodecyl dimethyl tertiary amine evenly to obtain a mixed material, mix the mixed material with 25g sodium hydroxide, and stir for 10min at a temperature of 50°C under normal pressure to make it After complete reaction, a translucent light yellow paste is obtained, which is the spodumene ore flotation collector.

Abstract

The invention relates to the technical field of mineral flotation, and discloses a spodumene flotation collector and a preparation method thereof and a spodumene flotation method. The spodumene flotation collector is prepared from the following components: 10-30 parts of dodecyl dimethyl tertiary amine, 150-450 parts of vegetable oleic acid and 25-75 parts of sodium hydroxide. The preparation method of the spodumene flotation collector comprises the following steps that the vegetable oleic acid and the dodecyl dimethyl tertiary amine are mixed evenly to obtain a mixed material; and the mixed material is mixed with the sodium hydroxide, heated and stirred until the reaction is complete to obtain the spodumene flotation collector. The invention further provides a spodumene flotation method by adopting the spodumene flotation collector. By using the spodumene flotation collector, spodumene can be subjected to flotation under normal temperature, the collection capacity can be effectively exerted under low temperature, and meanwhile, the spodumene flotation collector can be applied to low-grade spodumene ore, and spodumene concentrate with high grade and recovery rate can be obtained.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a spodumene ore flotation collector, a preparation method thereof and a spodumene ore flotation method. Background technique [0002] Lithium is an important energy metal. Its application in high-energy lithium batteries and controlled thermonuclear reactions makes it an important raw material to solve long-term energy supply for human beings. Lithium series products are widely used in smelting, refrigeration, atomic energy, aerospace, ceramics, glass, grease, rubber, welding, medicine, batteries and other industries. In recent years, with the gradual popularization and application of lithium-ion batteries in the fields of electric vehicles and aerospace power supplies, the demand for lithium in the world has increased dramatically. [0003] Lithium resources are mainly found in granite-pegmatite deposits and salt lake brine deposits, but the extraction of lithium from...
