Embodiment 1
[0027] The preparation of collector: by weight, get 50 parts of saponified fatty acids (oxidized paraffin wax soap, derived from Wuhan Kanos Technology Co., Ltd.), 10 parts of naphthenic acid soaps (derived from Hebei Province Guangping Shangyuan mineral processing aid Co., Ltd.), 10 parts of hydroxamic acid (salicylic hydroxamic acid, derived from Zhengzhou Yuhe Chemical Products Co., Ltd.), 10 parts of primary amine (laurylamine, derived from Hubei Hengjingrui Chemical Co., Ltd.), 2 parts of glacial acetic acid (sourced Chengdu Dinghengda Chemical Products Co., Ltd.), 1 part of sodium hydroxide (from Chengdu Dinghengda Chemical Products Co., Ltd.), 1 part of sulfuric acid (from Chengdu Dinghengda Chemical Products Co., Ltd.), fully mixed; 10 times the total weight of water is added to the material, and it is fully stirred for 20 minutes under the condition of a water bath at 40°C to obtain a flotation ilmenite combined collector.
[0028] Taking medium and low-grade ilmenite...
Embodiment 2
[0030] The preparation of collector: by weight, with 42 parts of saponified fatty acids (oxidized paraffin wax soap), 12 parts of naphthenic acid soaps, 15 parts of hydroxamic acid (salicylic hydroxamic acid), 14 parts of primary amines (laurylamine), 7 parts Mix 1 part of glacial acetic acid, 3 parts of sodium hydroxide, and 2 parts of sulfuric acid; add water 5 times the weight of the above product, and stir in a water bath at 60°C for 20 minutes to obtain a combined collector for flotation ilmenite.
[0031] Taking medium and low-grade ilmenite in a concentrator in Panzhihua, Sichuan as the ore sample, TiO 2 The grade is 15.21%. Add the collector of the present invention in an amount of 250g / t, use it at a pulp temperature of 20°C, adjust the pH of the pulp to 5-6, and obtain TiO through a rough separation 2 The titanium concentrate with a grade of 52.69% has a recovery rate of 92.17%.
Embodiment 3
[0033] The preparation of collector: by weight, with 40 parts of saponified fatty acids (tal oil soap), 15 parts of naphthenic acid soaps, 20 parts of hydroxamic acid (octyl hydroxamic acid), 15 parts of primary amines (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 product, and stir in a 60°C water bath for 15 minutes to obtain a combined collector for flotation ilmenite.
[0034] Taking medium and low-grade ilmenite in a concentrator in Panzhihua, Sichuan as the ore sample, TiO 2 The grade is 18.32%. Add the collector of the present invention in an amount of 300g / t, use it at a pulp temperature of 20°C, adjust the pH of the pulp to 5-6, and obtain TiO through a rough separation 2 The grade is 49.58% titanium concentrate, and the recovery rate is 90.31%.
