Embodiment 1

[0017] Weigh 7Kg of C5-9 hydroxamic acid, 1.5Kg of mediylan and C 11-16 Alkane kerosene 1.5Kg; The above-mentioned raw materials are added in the stirred tank successively according to the above-mentioned order, at normal temperature and pressure, under the condition of a stirring speed of 200 rpm, the stirring time is 1.5h to obtain the rare earth mineral collector of the present invention.

[0018] Effect test

[0019] Rare earth ore flotation (Ce, La) 2 o 3 Coarse concentrate: Wet-grind the rare earth ore until the fineness -0.074mm accounts for more than 75%, adjust the pH=9, use the rare earth mineral collector prepared in the previous step for flotation, and add 100g / t to obtain (Ce, La) 2 o 3 Coarse concentrate.

[0020] Comparative test: replace the rare earth mineral collector with hydroxamic acid soap, the addition amount and other steps are the same.

Embodiment 2

[0024] Weigh C 5-9 Hydroxamic acid 7.5Kg, Medialan 1.0Kg and C 11-16 Alkane kerosene 1.5Kg; The above-mentioned raw materials are added in the stirred tank successively according to the above-mentioned order, and at normal temperature and pressure, under the condition of a stirring speed of 200 rpm, the stirring time is 1h to obtain the rare earth mineral collector of the present invention.

[0025] Effect test:

[0026] Rare earth ore flotation (Ce, La) 2 o 3 Coarse concentrate: use the rare earth mineral collector prepared in this example, the addition amount is 80g / t, and the rest of the steps are the same as in Example 1 Rare earth ore flotation (Ce, La) 2 o 3 Coarse concentrate test.

[0027] Xenotime Flotation Y 2 o 3 Coarse concentrate: use the rare earth mineral collector prepared in this embodiment, the addition amount is 80g / t, the steps are the same as the xenotime flotation Y in embodiment 1 2 o 3 Coarse concentrate test.

Embodiment 3

[0029] Weigh C 5-9 Hydroxamic acid 8Kg, Medialan 1.0Kg and C 11-16 Alkane kerosene 1.0Kg; The above-mentioned raw materials are added in the stirred tank successively according to the above order, at normal temperature and pressure, under the condition of a stirring speed of 200 rpm, and a stirring time of 1.2h to obtain the rare earth mineral collector of the present invention.

[0030] Rare earth ore flotation (Ce, La) 2 o 3 Coarse concentrate: use the rare earth mineral collector prepared in this example, the addition amount is 120g / t, and the rest of the steps are the same as in Example 1 Rare earth ore flotation (Ce, La) 2 o 3 Coarse concentrate test.

[0031] Xenotime Flotation Y 2 o 3 Coarse concentrate: use the rare earth mineral collector prepared in this embodiment, the addition amount is 120g / t, the steps are the same as the xenotime flotation Y in embodiment 1 2 o 3 Coarse concentrate test.

Abstract

The invention provides a rare-earth mineral collecting agent. The rare-earth mineral collecting agent comprises, by weight, 70-90 parts of C5-9 hydroximic acid, 5-15 parts of Medialan and 5-15 parts of C11-16 alkane kerosene. The rare-earth mineral collecting agent is good in selectivity, wide in pH applied range and high in collecting capacity.

Description

technical field [0001] The invention belongs to the field of mineral flotation, in particular to a rare earth mineral collector. Background technique [0002] At present, with the continuous development and utilization of mineral resources, the resources are becoming increasingly depleted, the grade of rare earth minerals is low and the mineral properties are complex. Minerals are selective collectors and have important practical significance. [0003] At present, the rare earth ore collectors that occupy a dominant position in the rare earth flotation process include oleic acid, oleic acid soap, hydroxamic acid, hydroxamic acid soap, oxidized paraffin wax soap, tall oil, tall oil soap, Medea Lan et al., wherein mediylan is synthesized by the condensation of coconut oil fatty acid and methylglycine, and the general structural formula is: [0004] The single use of the above-mentioned collectors has problems such as poor selectivity, large dosage of chemicals, many dosing...
