Problems solved by technology

Without exception, these agents can exert inhibitory effects only under alkaline conditions, that is, the above-mentioned inhibitors can only be used after the flotation environment is transformed into an alkaline environment, which not only increases the workload of the process, but also complicates the operation of the process
However, there are very few reports on the inhibition of sphalerite under natural pH conditions.

Embodiment 1

[0016] Weigh the barks of pine, mulberry, and persimmon trees according to the mass percentage 1:1, put each bark into a pulverizer after mixing, and then pass through a 140-mesh sieve. The resulting material after sieving is a bark mixture, and the bark The mixture and sodium carbonate are mixed according to the mass ratio of 1:3, and water is added to prepare a solution with a mass concentration of 30%, which is allowed to stand for 10 hours, and then put into a beaker to heat the solution and keep the temperature at 70-75°C for cooking. The substance obtained after drying is set aside, then the substance is mixed with sodium humate at a mass ratio of 1:2, and water is added to prepare a solution with a mass concentration of 35%. Cooking is carried out, and the obtained after the water is completely evaporated is the sphalerite inhibitor.

Embodiment 2

[0018] Take eucalyptus, pomegranate bark by mass percentage 1:1.2, put into pulverizer after each bark is mixed and pulverize, pass 150 mesh sieves then, the gained material after sieving is bark mixture, bark mixture and vulcanization The mass ratio of sodium is 1:4, add water to prepare a solution with a mass concentration of 35%, let it stand for 11 hours, then put it into a beaker to heat the solution and keep the temperature at 70-75°C for cooking, and obtain it after the water is evaporated to dryness The substance is set aside, then the substance is mixed with sodium humate at a mass ratio of 1:2.5, and water is added to prepare a solution with a mass concentration of 30%, and the resulting solution is stirred for 3 hours to make the mixture even, and then cooked at 65-75°C. After the water is completely evaporated, the inhibitor of sphalerite is obtained.

Embodiment 3

[0020] Take mulberry tree, persimmon tree, pomegranate bark by mass percentage 1:1.5, put into pulverizer after each bark is mixed and pulverize, then pass 170 mesh sieves, the obtained material after sieving is bark mixture, bark The mixture and sodium carbonate are mixed according to the mass ratio of 1:3, and water is added to prepare a solution with a mass concentration of 30%, which is allowed to stand for 10 hours, and then put into a beaker to heat the solution and keep the temperature at 70-75°C for cooking. The substance obtained after drying is set aside, then the substance is mixed with sodium humate at a mass ratio of 1:2, and water is added to prepare a solution with a mass concentration of 35%. Cooking is carried out, and the obtained after the water is completely evaporated is the sphalerite inhibitor.

Abstract

The invention discloses a marmatite inhibitor preparation method. The method comprises the steps that (1) bark is weighed and obtained according to the mass percent ranging from 1:1 to 1:1.5, the bark is smashed and screened, and a mixture A is obtained; (2) the mixture A and sodium carbonate or sodium sulfide are mixed according to the mass percent ranging from 1:3 to 1:4 and are added with water to form a solution with the mass percentage concentration ranging from 30% to 35%, the solution is made to stand, and is heated and cooked, and a substance B is obtained after water is completely evaporated; (3) the substance B and sodium humate are mixed according to the mass percent ranging from 1:2 to 1:2.5 and added with water to form a solution, the solution is stirred for 2 h to 3 h, then is cooked at 65 DEG C to 75 DEG C, and finally a marmatite inhibitor is obtained after water is completely evaporated. The marmatite inhibitor can achieve flotation separation for jamesonite and marmatite on the natural pH condition, medicament dosage is mall, the marmatite inhibitor is good in solubility, innocuous and free of pollution, the flotation technological process in the prior art is simplified, operation is easier, and meanwhile the technological cost is reduced.

Description

technical field [0001] The invention relates to a preparation method of a mineral inhibitor, in particular to a preparation method of a sphalerite inhibitor. Background technique [0002] In the process of flotation separation of sphalerite and sphalerite, due to the close floatability of sphalerite and sphalerite, it is generally preferred to suppress the sphalerite and then flotation the sphalerite Flotation separation process. In the flotation separation process, lime is used to adjust the pH and then inhibitors are added to realize the separation of lead-zinc minerals. Currently, except for cyanide, zinc sulfate and other agents are used to inhibit sphalerite. Without exception, these agents can exert inhibitory effects only under alkaline conditions, that is, the above-mentioned inhibitors can only be used after the flotation environment is transformed into an alkaline environment, which not only increases the workload of the process, but also complicates the operation...
