The invention relates to a composite material of a binder and a preparation method thereof, and particularly relates to a using method of a granulation binder for chloride-leaching incineration residue. The using method comprises the following steps of: a preparing a binder; b bonding the chloride-leaching incineration residue; and c pelletizing, then firing to recover nickel-copper noble metal after pelletizing. The chloride-leaching incineration residue is bonded by using the binder, wherein the binder is prepared from sodium hydroxide or calcium hydroxide solution, and starch or modified cellulose solution. Thus, the using method is low in cost and convenient to popularize and use. Continuous agitation is needed when the chloride-leaching incineration residue is bonded by the binder; local agglomeration of the chloride-leaching incineration residue is prevented; the chloride-leaching incineration residue is clustered and hardened after being pelletized in a ball press machine, and then put into an alloy vulcanizing furnace to fire; no simple substance sulfur is separated out; and no splicing and agglomeration phenomena of the simple substance sulfur are generated in a secondary combustion chamber, a flue and an induced draft fan. In addition, the binder is used for carrying out pretreatment on the chloride-leaching incineration residue, thus, the recovery rate of the noble metal can be greatly increased; and the yield of the nickel-copper noble metal is also increased to over 90%.
