The residue from the treatment of effluents from the galvanizing industries is called galvanic sludge and has potentially toxic metals in it. Incorrect disposal of galvanic sludge can cause damage to the environment and health. The work sought to evaluate the feasibility of using galvanic sludge in the production of inorganic pigments. Characterization of the residue was carried out using atomic absorption spectroscopy, X-ray fluorescence, moisture determination, sieve granulometry, fire loss, thermogravimetry, and differential thermal analysis. The results obtained bought the possibility of p production of pigments with galvanic sludge.
