Abstract
The present invention relates to dearsenifying process to eliminate arsenic impurity chemically in wet metallurgy, and is especially process of dearsenifying copper sulfate solution. The copper sulfate solution dearsenifying process includes adding natrojarosite slag into copper sulfate solution, regulating pH to 0.5-2, heating to 70-100 deg.c, adding oxidant and maintaining the temperature to oxidize for 0.5-3 hr, regulating pH to 3.5-5, reacting for 10-30 min and filtering to obtain dearsenified copper sulfate solution. During the process, the Fe3+ and Fe2+ ions of natrojarosite slag are dispersed in the solution and converted into Fe(OH)3 colloid with strong adsorption capacity to eliminate arsenic and other impurities from the solution. The process has short period, low cost, no introduction of other impurity and high dearsenifying.
Description
Technical field
A kind of method of deeply removing arsenic from copper sulfate solution relates to the method for removing arsenic in the hydrometallurgy, is applicable to the arsenic content in chemical method removal arsenic content higher the impurity material, particularly copper-bath.Used arsenic removing agent adopts the yellow modumite waste residue that produces in the nonferrous metallurgical process during arsenic removal, does not need to use pure chemistry reagent.
Background technology
Arsenic is mixed in the product, can color and luster, the performance of product be exerted an influence, and the use of limits product, arsenic is a kind of highly toxic substance simultaneously, can cause wound to HUMAN HEALTH in processing, use.Arsenic existing way complexity in material, the product is difficult to the degree of depth and deviate from purifies, and the method for existing arsenic removal mainly contains extraction process, resin method, parco-lubrizing etc., but these methods exist that range of application is narrow, long flow path, cost height, and easily introduces shortcoming such as other impurity.
Summary of the invention
The objective of the invention is at the deficiency on the above-mentioned prior art, provide that a kind of flow process is short, cost is low, do not introduce other impurity, the method for deeply removing arsenic from copper sulfate solution that can deep purifying.
The objective of the invention is to be achieved through the following technical solutions.
A kind of method of deeply removing arsenic from copper sulfate solution, it is characterized in that the arsenic removal process is that iron vitriol dreg of yellow sodium is added in the copper-bath, regulating pH is 0.5～2, be warming up to 70～100 ℃, add oxygenant insulation oxidation after 0.5～3 hour, again pH value of solution is adjusted to 3.5～5, in 10～30 minutes reaction times, obtains qualified solution after filtration.
