Abstract

Disclosed are a cadmium removing process in zinc-containing solution purification with better cadmium removing effect and a purification method of zinc-containing solution with desired purification effect. The cadmium removing process in zinc-containing solution purification in the present invention includes following steps: 1) removing colloid from neutral leachate or supernatant of the neutral leachate after precipitation to obtain zinc-containing solution with colloid content less than or equal 50 mg/L; 2) performing zinc powder substitution in zinc-containing solution to at least replace cadmium; 3) carrying out solid-liquid separation to filter the zinc-containing solution containing impurity of cadmium, wherein filtering time is controlled within 60 minutes and filter precision is controlled within 10μm. In the present invention, the process of removing colloid from neutral leachate or supernatant first and then performing zinc powder substitution and filtration for solid-liquid separation is provided creatively and the selection and collocation of the key parameters such as colloid content in the zinc-containing solution after removing colloid and the filtering time and filter precision when filtering for solid-liquid separation is also provided to determine the final cadmium removing process.
