摘要：In this paper we established the optimum conditions of heavy metals removal from sludge resulted from industry and we tried to put these metals in good use. In order to establish the optimum conditions of heavy metals removal we studied the influence of the used acids concentrations, the influence of the agitation time, of the liquid: solid ratio and we tried to recover the extracted metals by using disodium phosphate with ammonia solution and sodium carbonate solution.
