ABSTRACT:
This invention provides a method for stabilization of lead smelter slag and matte subject to acid and water leaching tests or leach conditions by addition of stabilizing agents into the smelter feed such that leaching of lead is inhibited to desired levels. The resultant waste after stabilization is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.
