The solubility products of metal sulfides are several orders of magnitude lower than those of the corresponding hydroxides. This should make it feasible to precipitate the heavy metals from solutions containing complexing agents that prevent metal removal by hydroxide precipitation.Also, the pH range for the precipitation of metals as sulfides is much broader.

steel, scrap, and direct reduced iron. EAF is a batch process with a cycle time of about two to three hours. Since the process uses scrap metal instead of molten iron, coke making or iron making operations are eliminated. These operations are discussed in separate documents. Electric arc furnaces (EAFs) can serve smaller, local markets.

Your choice. Sulfuric would be my first one, as industrial sulfuric acid is plentiful and thus cheap. Neutralize with Na or K hydroxide, add more hydroxide until precipitation stops. Perhaps you will need to filter to separate the acid solution of metal salts from whatever insoluble gunk occurs together with the metals.
