The purpose of this paper was identifying technological alternatives in order to get treatment or deposit the sulphides refination residues for reduces the impact on environment or obtain trade by products. To reach the objective patent and scientific article was consulted, permitting to define three variant for treatment or deposition of iron, two variants to copper and manganese residues, as unique alternative to calcium and magnesium residue. Resuming in options to evaluate the sulphides refination residues treatment or deposition where was considered: blender the iron, copper and manganese residues with tails of laterite ammonia carbonate leaching, obtain copper sulphate from copper residue, feed iron and manganese residues to laterite pressure acid leaching process joint with el mineral, and pour in "safety refill" the calcium and magnesium residues.

Palavras-chave : residues; iron; manganese; copper; calcium; magnesium.
