Abstract

The invention discloses a method for producing spherical basic nickel carbonate by using an ABS metallized material. The method comprises the following processing steps: plastic separation: crushing the ABS metallized material, putting the crushed ABS metallized material into a sulfuric acid solution of which the concentration in mass fraction is 20%, adding an oxidant, and stirring till ABS plastic is completely separated out; preparation of crude nickel sulfate: filtering a solution obtained after the above reaction, performing an electrodeposition reaction, and performing concentration to obtain a crude nickel sulfate crystal; preparation of fine nickel sulfate: mixing the crude nickel sulfate crystal with water and hydrogen peroxide, and performing filtration and extraction to obtain a fine nickel sulfate solution; and preparation of nickel carbonate: adding sodium carbonate into the fine nickel sulfate solution, adjusting the pH value to be 8, keeping the heating temperature and the stirring speed at 45 DEG C and 70 r/min correspondingly, continuing a reaction for 2.5 h, and then performing filtration, washing and drying to obtain spherical basic nickel carbonate. By adoption of the method disclosed by the invention, high-apparent-density spherical basic nickel carbonate can be recovered from the ABS metallized material; the recovery efficiency is high; and the purity of recovered spherical basic nickel carbonate is high.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a method for producing spherical basic nickel carbonate by using ABS metal plating material. Background technique [0002] The purpose of plastic electroplating is to coat the plastic surface with metal to form a plastic metal plating material, which not only increases the appearance, but also compensates for the shortcomings of plastic, endows the properties of metal, and gives full play to the characteristics of plastic and metal. Today, there are a large number of plastic electroplating Products are used in industries such as electronics, automobiles, and household goods, so there are a lot of waste plastic electroplating materials. In plastic electroplating, ABS plastic metal plating materials are the most widely used, and the electroplating effect is the best. In order to improve resource utilization, for plastics Metallized waste needs to be recycled, but because plastic an...
