Method for preparing bricks by waste residues of cyanidation slag after recleaning of copper, lead and sulfur
The invention relates to a method for preparing bricks by waste residues of cyanidation slag after recleaning of copper, lead and sulfur. The method comprises the steps: r remeducing sulfur;oving cyanogen; carrying out slaking reaction; carrying out moulding and steam curing; cutting blank; carrying out high pressure steam curing and the like. The method provided by the invention has the beneficial effects: 1) aerated bricks prepared by virtue of the method have a lot of pores and micropores, have good heat insulation performance and are high in compressive strength; 2) the process flow is simple, and raw materials are low in price and easily available, so that the method is easily implemented; 3) wastes are turned into wealth, so that the utilization ratio of resources is improved and the environmental pollution is reduced.
