Embodiment 1

[0020] Take 10kg of the above ore and process it according to the following steps:

[0021] Step 1, ore leaching:

[0022] Grind the ore to a particle size of -0.074mm with a mass percentage of 90%, and adjust the pulp to a pulp concentration of 30%. Add ammonia water until the pH value of the pulp is 11, stir for 1 hour, and then add amino acid, the dosage is 10g / L, and stir. leaching for 12-24h;

[0023] Step 2, leaching solution extraction:

[0024] The ore pulp treated in the first step is subjected to pressure filtration to obtain the leaching precious liquid, and the solid micro-particle impurities in the leaching precious liquid are removed by a centrifuge, and then mixed and stirred with an alkaline chelated copper extractant N910 with a mass concentration of 10% to remove the leaching precious liquid. The impurity leached precious liquid is mixed with copper extractant N910 with a mass concentration of 10% in a ratio of 1:1 by volume, and the raffinate is returned t...

Abstract

The invention belongs to the technical field of hydrometallurgy, and specifically relates to a method for producing copper sulfate by using low-grade copper oxide ore. The ore is leached with amino acids under alkaline conditions, and the leached precious liquid is extracted with an extractant to obtain copper-containing organic compounds. The phase was washed with water, and the copper-containing organic phase after the water washing was stirred and back-extracted with an acidic saturated copper sulfate solution, filtered, and dried. The invention realizes high-efficiency utilization of low-grade copper oxide ore resources, and the method has simple process, low production cost and good economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of hydrometallurgy, and in particular relates to a method for producing copper sulfate by utilizing low-grade copper oxide ore. Background technique [0002] At present, the production raw materials of copper sulfate are mainly copper concentrate and copper-containing industrial scraps. The main processes used in the production process are sulfuric acid leaching, impurity removal, evaporation, crystallization and drying. The key technology is the removal of other metal impurities in the liquid, mainly the removal of iron ions. The prior art CN1034590C provides that copper sulfate is prepared by adopting low-grade copper oxide ore through acid leaching, thermal clarification, filtration, pH adjustment to remove other metal ion impurities, evaporation, crystallization and drying processes, and the process is long and the operating conditions are complicated. Production costs are high. [0003] To sum up, in ...
