Embodiment 1

[0026] A kind of high-efficiency formula of composite type replacing salicylaldoxime class copper extractant TH5774 among the present invention is as shown in table 1:

[0027] Table 1

[0028] components

[0029] The specific preparation method of the compound-type substituted salicylaldoxime copper extractant TH5774 of the present invention is as follows: 370 grams of modifiers, 50 grams of kerosene, and self-made intermediate 5-decyl salicylaldoxime are added sequentially in a 2000 ml three-necked bottle, which contains 5-(1,1,6-trimethylheptyl) salicylaldoxime 320 grams, 5-(1,1,2-trimethylheptyl) salicylaldoxime 160 grams, 5-(1-methyl-1- 100 grams of butylamyl) salicylaldoxime, heated up to 80 degrees under mechanical stirring until completely clarified, about 2 hours to obtain 1000 grams of amber product.

Embodiment 2

[0031] A kind of high-efficiency formula of composite type replacing salicylaldoxime class copper extractant TH222 among the present invention is as shown in table 2:

[0032] Table 2

[0033] components

[0034] The specific preparation method of the composite type substituted salicylaldoxime copper extractant TH222 of the present invention is as follows: 370 grams of modifiers and 50 grams of kerosene are added successively in a 2000 milliliter three-necked bottle, and the self-made intermediate replaces salicylaldoxime, which contains 4-( 8,11,14-pentadecatrienyl) salicylaldoxime 140 grams, 4-(8,11-pentadecadienyl) salicylaldoxime 140 grams, 4-(8-pentadecenyl) salicylaldoxime 140 grams, 4-pentadecyl salicylaldoxime 160 grams. Raise the temperature to 80°C and stir mechanically until completely clarified. It takes about 2 hours to obtain 1000 grams of an amber product.

Abstract

The invention discloses a multicomponent compound salicylaldoxime copper extractant which belongs to the technical field of hydrometallurgy copper extraction and a preparation method thereof. The extractant which treats a salicylaldoxime mixture as an active component has the advantages of strong copper extraction capability, fast extraction speed, no flocculation, easy back extraction, high pure copper transfer rate, low consumption, and less residual of copper ions in mine tailings through comparing with traditional products. The copper extractant treats industrial byproducts mixed with decylene or cardanol as raw materials, so the preparation method is simple.

Description

technical field [0001] The invention belongs to the technical field of hydrometallurgical copper extraction, and in particular relates to a multi-component composite substituted salicylaldoxime copper extractant and a preparation method thereof. Background technique [0002] my country is rich in copper ore resources, but most of them are associated mines with low grade. The effective process for smelting this mineral is the "leaching-extraction-electrolysis" process. Extraction is a key step in the process, and copper extractant plays a decisive role as an important part of the technology. At present, most of the extraction agents used in my country's copper smelting industry rely on imports, mainly including the LIX series (LIX984, LIX984N, etc.) of Henkel Company, Acorga M5640, Acorga M5774 of Avecia Company, etc. composition. However, the formulas of imported copper extractants are mostly top secret, and most of them are expensive, and most of the copper mines in my co...
