Embodiment 1

[0027] Preparation of collector: by weight, take 50 parts of saponified fatty acid (oxidized paraffin soap, derived from Wuhan Carnos Technology Co., Ltd.), 10 parts of naphthenic acid soap (derived from Guangping Shangyuan mineral processing aid in Hebei Province) Co., Ltd.), 10 parts of hydroxamic acid (salicylic hydroxamic acid, sourced from Zhengzhou Yuhe Chemical Products Co., Ltd.), 10 parts of primary amine (laurylamine, sourced from Hubei Hengjingrui Chemical Co., Ltd.), 2 parts of glacial acetic acid (sourced from Hubei Hengjingrui Chemical Co., Ltd.) In Chengdu Dinghengda Chemical Products Co., Ltd.), 1 part sodium hydroxide (from Chengdu Dinghengda Chemical Products Co., Ltd.), 1 part sulfuric acid (from Chengdu Dinghengda Chemical Products Co., Ltd.), mix well; add to the mixture 10 times the total weight of water was added to the feed, and the mixture was fully stirred for 20 minutes under the condition of a 40° C. water bath to obtain a flotation ilmenite combined...

Embodiment 2

[0030] The preparation of collector: by weight, 42 parts of saponified fatty acid (oxygenated paraffin soap), 12 parts of naphthenic acid soap, 15 parts of hydroxamic acid (salicylic hydroxamic acid), 14 parts of primary amine (laurylamine), 7 parts of Parts of glacial acetic acid, 3 parts of sodium hydroxide, and 2 parts of sulfuric acid were mixed; water 5 times the weight of the above-mentioned product was added, and the mixture was fully stirred in a 60° C. water bath for 20 minutes to obtain a flotation ilmenite combined collector.

[0031] Taking medium and low grade ilmenite from a concentrator in Panzhihua, Sichuan as the ore sample, TiO 2 The grade is 15.21%, the dosage of the collector of the present invention is 250g / t, and it is used at a pulp temperature of 20 ° C. The pH of the pulp is adjusted to 5-6, and TiO can be obtained after a rough selection. 2 The grade of ilmenite concentrate was 52.69%, and the recovery rate was 92.17%.

Embodiment 3

[0033] The preparation of collector: by weight, 40 parts of saponified fatty acid (Tal oil soap), 15 parts of naphthenic acid soap, 20 parts of hydroxamic acid (octyl hydroxamic acid), 15 parts of primary amine (n-decyl) amine), 10 parts of glacial acetic acid, 5 parts of sodium hydroxide, and 5 parts of sulfuric acid; add water 20 times the weight of the above-mentioned result, and fully stir in a 60° C. water bath for 15 minutes to obtain a flotation ilmenite combined collector.

[0034] Taking medium and low grade ilmenite from a concentrator in Panzhihua, Sichuan as the ore sample, TiO 2 The grade is 18.32%, the amount of the collector of the present invention is 300g / t, and it is used at a pulp temperature of 20 ° C. The pH of the pulp is adjusted to 5-6, and TiO can be obtained after a rough selection. 2 The grade of ilmenite concentrate was 49.58%, and the recovery rate was 90.31%.

Abstract

The invention provides an ilmenite high-efficiency flotation separation combined collector and a preparation method and application thereof, belonging to the technical field of mineral processing. Wherein the collector includes the following components in parts by weight: 40-50 parts of saponified fatty acid, 10-15 parts of naphthenic acid soap, 10-20 parts of hydroxamic acid, 10-15 parts of primary amine, glacial acetic acid 2 to 10 parts, 1 to 5 parts of sodium hydroxide and 1 to 5 parts of sulfuric acid. The collector provided by the invention greatly saves the cost of mineral separation and purification, has the advantages of good collection performance, good selectivity and efficient separation, and has good flotation separation effect on ilmenite, and can be used for lower-grade minerals. The raw ore is separated by efficient flotation, and the obtained ilmenite concentrate has high grade and high recovery rate.

Description

technical field [0001] The invention belongs to the technical field of beneficiation, in particular to an ilmenite high-efficiency flotation separation combined collector and a preparation method and application thereof. Background technique [0002] Titanium is a very important strategic metal in the 21st century with a wide range of applications in aerospace, shipbuilding, medical devices and catalysis. Ilmenite, an oxide mineral of iron and titanium, is the main ore from which titanium is extracted. There are more than 20 provinces and cities in China with titanium ore, especially in Panxi area of ​​Sichuan and Chengde area of ​​Hebei. The Panxi area is the largest production base of ilmenite concentrate in my country. According to the nature of the deposit, it is divided into gabbro-type and peridotite-type ilmenite. Gabbro-type ilmenite usually adopts the process of "slag separation → first-stage iron removal → first-stage strong magnetic → grinding → second-stage iro...
