Embodiment 1

[0018] This embodiment is a kind of xanthate for ore dressing, which includes 290 kg of raw material alcohol in parts by weight, 255 kg of sodium hydroxide, and 480 kg of carbon disulfide; in this embodiment, the aforementioned raw material alcohol adopts ethanol, and its specific industrial preparation Methods as below:

[0019] Step 1, get the corresponding amount of ethanol, carbon disulfide and sodium hydroxide, add ethanol in the kneader, then add carbon disulfide and sodium hydroxide in ethanol, make the three react according to the following formula:

[0020] ROH+CS 2 +NaOH=ROSSSNa+H 2 o

[0021] Step 2: reacting ethanol, carbon disulfide and sodium hydroxide to generate xanthate; packaging the xanthate to obtain the finished product of xanthate for mineral processing.

[0022] In this example, ethyl xanthate was synthesized by the above preparation method, wherein the total weight of ethanol, carbon disulfide and sodium hydroxide accounted for 82% of the total weigh...

Embodiment 2

[0024] This embodiment is a kind of xanthate for ore dressing, which includes 396 kg of raw material alcohol in parts by weight, 218 kg of sodium hydroxide, and 410 kg of carbon disulfide; in this embodiment, the aforementioned raw material alcohol adopts butanol, and its specific industrial The preparation method is as follows:

[0025] Step 1, get corresponding amount of butanol, carbon disulfide and sodium hydroxide, add butanol in the kneader, then add carbon disulfide and sodium hydroxide in butanol, make the three react according to the following formula:

[0026] ROH+CS 2 +NaOH=ROSSSNa+H 2 o

[0027] In this step, sodium hydroxide (i.e. caustic soda) is stored in the alkali tank, and the pipeline is communicated with the kneader, and the pipeline is also equipped with a soda adding machine, and the hydrogen in the soda tank is quantified by the soda adding machine. Sodium oxide is transferred to the kneader;

[0028] Step 2, butanol, carbon disulfide and sodium hydr...

Embodiment 3

[0031] This embodiment is a kind of xanthate for ore dressing, which includes 396 kg of raw material alcohol in parts by weight, 218 kg of sodium hydroxide, and 410 kg of carbon disulfide; in this embodiment, the aforementioned raw material alcohol adopts isobutanol, and its specific The industrial preparation method is as follows:

[0032] Step 1, get corresponding amount of isobutanol, carbon disulfide and sodium hydroxide, add isobutanol in the kneader, then add carbon disulfide and sodium hydroxide in isobutanol, make the three react according to the following formula:

[0033] ROH+CS 2 +NaOH=ROSSSNa+H 2 o

[0034] In this step, sodium hydroxide (i.e. caustic soda) is stored in the alkali tank, and the pipeline is communicated with the kneader, and the pipeline is also equipped with a soda adding machine, and the hydrogen in the soda tank is quantified by the soda adding machine. Sodium oxide is transferred to the kneader; when the reaction of isobutanol, carbon disulfi...

Abstract

The invention discloses a xanthate for beneficiation and a preparation method thereof, and belongs to a beneficiation adjuvant. The xanthate comprises, by weight, 280-410 parts of raw material alcohol, 400-500 parts of carbon disulfide and 200-270 parts of sodium hydroxide; and the raw material alcohol is any one of ethanol, butanol and isobutanol. The production process of the xanthate is simplified by simplifying the composition proportion of the xanthate; a kneading machine is used for assisting in the preparation method, so that the production efficiency of the xanthate is further improved, and the production cost is also reduced; and meanwhile, the xanthate for beneficiation and the preparation method for the xanthate are simple to operate and is suitable for the production at variousplaces and regions, so that the application range is wide.

Description

technical field [0001] The invention relates to a mineral processing auxiliary agent, more specifically, the present invention mainly relates to a mineral processing xanthate and a preparation method thereof. Background technique [0002] The chemical name of xanthate is hydrocarbyl dithiocarbonate, which is divided into ethyl xanthate, butyl xanthate, amyl xanthate and so on. Xanthate is the most commonly used collector for flotation of sulfide minerals such as galena, chalcopyrite, sphalerite, pyrite, natural gold, natural silver, mercury, and malachite. Mineral dressing reagents are important raw materials used in mineral processing production in mines. The specificity of users determines the subordination of the product market, that is, the production situation of mines is positively related to the market demand for mineral dressing reagent products. Besides, except for the time period affected by the financial crisis, the domestic and foreign market demand for mineral ...
