Embodiment 1

[0014] The example of the regulation and control method of zinc oxide flotation foam of the present invention is made up of the following steps:

[0015] (1) Prepare combined defoamer: mix tributyl phosphate by weight: lauryl mercaptan: kerosene = 20:5:1, dissolve in water, and make a solution with a weight concentration of 20%,

[0016] (2) The solution prepared in (1) was stirred for 30 minutes until a uniform and stable pale yellow liquid was formed,

[0017] (3) When adding the prepared combined defoamer to adjust the foam during the flotation process, in order to facilitate the observation of the change in the height of the foam layer and the change in the foam structure, the baffle plate is used to raise the partition plate in the flotation cell of the flotation machine to the same level as A columnar space is formed at the same height on both sides of the tank to control the foam. After adding various chemicals in this columnar space, inflate with a fixed amount of air,...

example

[0019] The second example of the regulation and control method of zinc oxide flotation foam of the present invention is made up of the following steps:

[0020] (1) Prepare combined defoamer: mix tributyl phosphate by weight: dodecyl mercaptan: kerosene=16:4:1.5, dissolve in water, and make a solution with a weight concentration of 20%,

[0021] Steps (2 and (3) are the same as in Example 1.

Embodiment 3

[0023] The third example of the regulation and control method of zinc oxide flotation foam of the present invention is made up of following steps:

[0024] (1) Prepare combined defoamer: mix tributyl phosphate by weight: lauryl mercaptan: kerosene=30:2:1, dissolve in water, and make a solution with a weight concentration of 20%,

Abstract

The invention discloses a regulating method for zinc oxide flotation froth and belongs to the technical field of beneficiation. The regulating method comprises the following steps that firstly, a combined antifoaming agent is prepared, wherein by weight ratio, tributyl phosphate, dodecanethiol and kerosene are mixed according to the proportion being (20-30):(3-6):(1-2) and are dissolved into waterto be prepared into a solution with the weight concentration being 20%; secondly, the solution prepared in the first step is stirred for 30 min till uniform and stable faint yellow liquid is formed;and thirdly, the prepared combined antifoaming agent is added in the flotation process to adjust froth, the froth amount and the froth structure are controlled in the zinc oxide flotation process by controlling the adding amount of the combined antifoaming agent, ore can be gathered more effectively, and the quality of concentrates is improved.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a method for regulating and controlling zinc oxide flotation foam, which is suitable for foam control in zinc oxide separation. technical background [0002] As we all know, zinc sulfide ore is relatively easy to be enriched by conventional methods, and the amount of foam is easy to control, and the foam structure is good, which makes the flotation index better. But as time goes by, the demand for production increases, the zinc sulfide ore resources are gradually exhausted, the grade of zinc oxide ore resources is low, the amount of foam in the sorting process is difficult to control, and the foam structure is poor, which makes the beneficiation index unsatisfactory. Zinc oxide ore resources are abandoned, so it is of great significance to control the amount of foam and foam structure in the flotation process of zinc oxide to effectively enrich minerals. [0003] Zinc...
