Problems solved by technology

Commonly used collectors for ilmenite flotation mainly include oleic acid, oxidized paraffin soap, hydroxamic acid, styrene phosphonic acid, styrene arsenic acid and combined collectors MOS, MOH, XT, TAO, R series collectors Practice has proved that most of the agents have achieved relatively ideal indicators, but there are still deficiencies, such as poor selectivity of fatty acid collectors, high toxicity of styrene arsine acid, high price of styrene phosphonic acid, combined collectors Disadvantages such as unclear components
[0004] At present, short carbon chain hydroxamic acids (generally no more than 8 C) such as benzohydroxamic acid, salicylic hydroxamic acid, 5,9-hydroxamic acid and octyl hydroxamic acid are the most widely used in industry. It has a good advantage in selectivity, but its collection ability is slightly weaker, so its application is limited

preparation example Construction

[0023] The preparation process of the ilmenite chelating collector is as follows: at room temperature, 10-30 parts of hydroxy fatty acid, 5-10 parts of alkyl sulfonate, 10-50 parts of carboxyhydroxamic acid and surfactant 1- 5 parts, mix, stir for 20-30min to make it evenly mixed, then add 5-15 parts of foaming agent. Then saponify with lye with a concentration of 5-15%, and the weight ratio of the compound mixture to lye is 1:1-1:5. Stir evenly at 30-50°C to fully saponify for 1-3 hours to obtain an ilmenite chelating collector.

[0024] In the above method, it is characterized in that the hydroxy fatty acid used includes α-hydroxy oleic acid, α-hydroxy linoleic acid, ricinoleic acid;

[0025] In the above method, it is characterized in that the alkylsulfonate used comprises sodium dodecylsulfonate, sodium dodecylbenzenesulfonate;

[0026] In the above method, it is characterized in that the carboxyhydroxamic acid used includes C8-C18 alkyl-3-carboxypropyl hydroxamic acid o...

Embodiment 1

[0033] Weigh 25 parts of α-hydroxyoleic acid, 10 parts of sodium dodecylsulfonate, 50 parts of dodecyl-3-carboxypropyl hydroxamic acid and 1 part of Triton-100, mix them, stir for 30 minutes, and then Add 15 parts of foaming agent BK201, and continue to stir for 30 minutes to obtain a homogeneous mixture. Dissolve 20 parts of sodium hydroxide in 150 parts of water, then slowly add it to the above solution, stir evenly at 50°C to fully saponify for 1.5 hours, and obtain an ilmenite chelating collector.

Abstract

The invention discloses an ilmenite chelation collecting agent, and relates to a beneficiation reagent in the mineral processing process, in particular to an ilmenite flotation collecting agent. The ilmenite chelation collecting agent is characterized in that the ilmenite chelation collecting agent is prepared through compounding of hydroxy fatty acid, alkane sulfonate, carboxylic hydroximic acid, a surface active agent and a foaming agent and through saponification synthesis. The ilmenite chelation collecting agent is suitable for flotation of low-grade ilmenite, and high-grade rough titanium concentrates with the high recovery rate can be obtained. In the chelation collecting agent, the carboxylic hydroximic acid is obtained through chemical modification and is mixed and compounded with the hydroxy fatty acid, the alkane sulfonate, the surface active agent and the foaming agent, the solubleness, the dispersibility and the selectivity of the collecting agent can be greatly improved through the saponification reaction, and therefore flotation of the low-grade ilmenite is achieved. In addition, the collecting agent is high in collecting force, good in selectivity and environment-friendly and has good market popularization value.

Description

technical field [0001] The invention relates to an ilmenite chelating collector, which relates to an ore dressing agent in a mineral processing process, in particular to an ilmenite flotation collector. Background technique [0002] my country's titanium resources are relatively rich and widely distributed in nature, but the main ones with industrial value are ilmenite and rutile. There are more than 20 provinces and cities in the country where titanium ore is distributed, especially in the Panxi area of ​​Sichuan and the Chengde area of ​​Hebei. my country's titanium resources mainly present the following characteristics: more ilmenite, less rutile; more primary ore, less secondary ore; more lean ore, less rich ore, which increases the difficulty of comprehensive utilization of titanium ore. Therefore, based on the current situation, strengthening the efficient development and utilization of resources is an inevitable choice to change the advantages of my country's titaniu...
