Embodiment 1

[0021] The weight components of a zinc oxide mineral beneficiation collector are:

[0022] Dodecyl amine 200g, hexadecyl amine 300g, octadecyl amine 450g, sodium dodecyl sulfonate 50g.

[0023] A preparation method of zinc oxide mineral beneficiation collector: Dodecameric primary amine, hexadecyl primary amine, eighteen primary amine and the active agent are weighed according to the above ratio and then poured into a heated and stirred reactor, and then poured into the weight Dissolved in 80-100g ethanol.

[0024] Slowly add 200g of water to the reaction kettle and heat it to 130°C. At this time, add 80g of sodium hydroxide and stir continuously for 2 to 3 hours. During the stirring process, keep the temperature at 130°C, and the mass concentration of sodium hydroxide is 30%. After cooling, a paste-like mixture is formed to obtain a paste-like new collector product.

Embodiment 2

[0026] The weight components of a zinc oxide mineral beneficiation collector are:

[0027] Dodecyl amine 250g, hexadecyl amine 300g, octadecyl amine 400g, sodium hexadecyl sulfonate 50g.

[0028] A preparation method of zinc oxide mineral beneficiation collector: Dodecameric primary amine, hexadecyl primary amine, eighteen primary amine and the active agent are weighed in proportion and poured into a heated and stirred reactor, and then poured into a weight 80-100g ethanol dissolves.

[0029] Slowly add 150-200g of water into the reaction kettle. When heated to 140°C, add 90g of sodium hydroxide and stir continuously for 2 to 3 hours. During the stirring process, keep the temperature at 140°C, and the mass concentration of sodium hydroxide is 32%. After cooling, a paste-like mixture is formed to obtain a new paste-like collector product.

Embodiment 3

[0031] The weight components of a zinc oxide mineral beneficiation collector are:

[0032] Dodecyl primary amine 180g, hexadecyl primary amine 300g, octadecyl primary amine 450g, dodecyltrimethylammonium chloride 70g.

[0033] A preparation method of zinc oxide mineral beneficiation collector: Dodecameric primary amine, hexadecyl primary amine, eighteen primary amine and the active agent are weighed in proportion and poured into a heated and stirred reactor, and then poured into a weight 80-100g ethanol dissolves.

[0034] Slowly add 150-200g of water into the reaction kettle. After heating to 150°C, add 90g of sodium hydroxide and stir continuously for 2 to 3 hours. During the stirring process, keep the temperature at 150°C, and the mass concentration of sodium hydroxide is 36%. After cooling, a paste-like mixture is formed to obtain a new paste-like collector product.

Abstract

The invention discloses a zinc oxide mineral dressing collector and a preparation method thereof, in particular to a metal zinc oxide mineral dressing collector and a preparation method thereof. The weight components of the zinc oxide mineral dressing collector include: Dodecyl amine accounts for 18%~25%, hexadecyl amine accounts for 25%~30%, octadecyl amine accounts for 38%~45%, and active agent 4%~7%. The present invention is a combination collector for zinc oxide mineral dressing, which is relatively low temperature resistant and can be used without heating the pulp. The grade can be increased by 1.7%, the recovery rate can be increased by 5.76%, and the cost of beneficiation can be greatly reduced, especially for the zinc oxide raw ore with high mud and deep oxidation.

Description

technical field [0001] The invention relates to a zinc oxide mineral dressing collector and a preparation method thereof, and relates to a collector for metal zinc oxide mineral dressing and a preparation method thereof. Background technique [0002] There are many kinds of minerals contained in zinc oxide ore, the ore structure is complex, and the associated components are very unstable. The ore contains high clay, iron oxide minerals, soluble salts and other gangues and other reasons, and contains a large amount of clay and limonite. The flotation index of zinc oxide ore in my country is still low due to the high content of soluble salts and other reasons. [0003] At present, the flotation of zinc oxide ore mainly uses a single primary amine as a collector. With the change of ore properties, a single collector can no longer obtain ideal flotation indicators. The composite collector has a synergistic effect in the flotation process and can effectively improve the concentra...
