Embodiment 1

[0045] This embodiment provides a foaming agent, which, in parts by weight, is composed of 70 parts of terpineol oil, 20 parts of n-octanol, 801 parts of polysorbate and 9 parts of diesel oil.

[0046] The preparation method of the foaming agent is as follows: under the conditions of normal temperature and normal pressure, terpineol oil and n-octanol are mixed at 80r / min for 15min, then polysorbate-80 is added at 100r / min and mixed for 10min, then diesel oil is added and then 60r / min is added. / min stirring for 20min to make it well mixed.

Embodiment 2

[0048] This embodiment provides a foaming agent, which, in parts by weight, is composed of 68 parts of terpineol oil, 21 parts of isooctyl alcohol, 1.5 parts of polysorbate-80 and 9.5 parts of diesel oil.

[0049] The preparation method of the foaming agent is as follows: under the conditions of normal temperature and pressure, terpineol oil and isooctanol are mixed at 60 r / min for 15 minutes, then polysorbate-80 is added at 75 r / min and mixed for 20 minutes, then diesel oil is added and then Stir at 85r / min for 12min to make it fully mixed.

Embodiment 3

[0051] This embodiment provides a foaming agent, which, in parts by weight, is composed of 71 parts of terpineol oil, 18 parts of n-octanol, 801 parts of polysorbate-801 and 10 parts of diesel oil.

[0052] The preparation method of the foaming agent is as follows: mixing terpineol oil, n-octanol and diesel oil at 75r / min for 10min under normal temperature and normal pressure, then adding polysorbate-80, and then stirring at 75rmin for 10min to make it fully mixed.

Abstract

The invention relates to a flotation foaming agent for minerals containing easy-to-float gangue and a preparation method of the flotation foaming agent, and aims at solving the problem that at present, useful minerals are easily mixed in the flotation process of the easy-to-float gangue, so that the loss of the useful minerals is caused. The flotation foaming agent comprises terpenic oil, octanol, polysorbate and diesel oil. The preparation method comprises the step of mixing terpenic oil, octanol, polysorbate and diesel oil according to a formula to obtain the flotation foaming agent. According to the flotation foaming agent provided by the invention, by compounding the foaming agent components and utilizing the synergistic advantages of the components, the inclusion loss of copper in the easy-floating gangue can be remarkably reduced, and the utilization rate of copper ore resources containing the easy-floating gangue is improved.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a flotation foaming agent for minerals that are easy to float gangue and a preparation method thereof. Background technique [0002] At present, copper is an important strategic resource, among which, copper sulfide ore resources account for more than 75% of the proven copper resources. Influenced by geological metallogenic factors, some copper sulfide ores contain more buoyant gangue minerals such as talc and serpentine. These buoyant gangue minerals are naturally hydrophobic and have excellent buoyancy. Conventional floating gangue minerals are used. If the beneficiation process is used to deal with such copper resources, these easily floating gangue minerals will float up with the copper minerals, which seriously affects the grade and recovery rate of copper concentrates. In order to utilize the copper ore resources containing easy-pumice gangue, the conventional m...
