Abstract
A method for preparing a basic copper carbonate is provided. The method includes: mixing a copper hydroxide with water to obtain a precursor slurry; adding an accelerator to the precursor slurry and mixing the two to obtain a first mixture; introducing gaseous carbon dioxide into the first mixture for reaction whereby obtaining a crude basic copper carbonate; and purifying the crude basic copper carbonate whereby obtaining the basic copper carbonate. The accelerator is at least one selected from the group consisting of an ammonia water and an ammonium salt.
