3) add acid dissolve: the chloride slag produced with 10% diluted hydrochloric acid dissolution chloridizing roasting, copper, gold and most of rare precious metal transform and enter in solution, and silver is stayed in pickling slag with the form of silver chloride solid;
4) extract silver: leach the silver in pickling slag with ammoniacal liquor, silver enters a point silver-colored solution with silver ammino ion form, divides silvering solution with hydrazine hydrate reduction, and output reduction silver powder, casts Ag positive plate and send electrorefining of silver, output silver simple substance;
5) electrolyzing gold: add the precious metals such as the gold in copper powder displacement pickle solution and form thick gold mud in pickle solution, press filtration process obtains thick gold mud and waste liquid, carry out control of Electric potentials by sulfuric acid, sodium chlorate and remove assorted element in thick gold mud to reach selectivity, directly positive plate ingot casting is carried out to the gold mud formed after removal of impurities, Jinyang pole plate cast send Gold electrolysis refining, output elemental gold;
6) copper is produced: the copper added in iron replacement solution to above-mentioned waste liquid forms copper sponge, washes copper sponge hydrochloric acid off residue iron filings, and namely clear water obtains copper after rinsing.
Further, described step 2) in cryogenic chlorinating roasting be within 15 minutes, volatilize lower boiling muriate by the low temperature chlorination stove roasting of about 200 DEG C, chloridizing roast in medium tempera-ture within 30 minutes, makes metals all in the anode sludge and metallic compound generate corresponding muriate by 600 DEG C of chloridizing roast in medium tempera-tures material.
Further, the flue gas that described roasting produces forms solid chemical compound and tower solution by multistage absorption, carries out synthetical recovery focus on it.
Further, described step 4) nitrous oxides exhaust gas of Ag electrolyte output, adopt reducing absorping method process.
Further, described step 4) ammonia-contaminated gas individual curing, the ammonia reclaimed wherein recycles.
Further, described step 7) in sodium hydroxide and sodium carbonate and the acid waste gas produced, adopt aqueous sodium hydroxide solution spray-absorption.
Further, the waste water of described each operation output, with sodium hydroxide and sodium carbonate neutralization, makes the various heavy metal ion precipitations in waste water, after press filtration, send copper metallurgy industry.
Compared with prior art, the method for the warm chlorination process process gold, silver and bronze anode sludge in this, to use in patented technology warm chlorination furnace as preatreating reactors, and is divided into two-stage roasting, eliminates tradition and steams selenium and divide copper flow process, roasting more fully thoroughly, shorten the production cycle; The method advantage distillation mainly contains valency metal gold and silver, copper, reduces fund and overstocks; Compare existing anode slime treatment process flow process waste liquid, waste residue is few, environmental pollution is little, and the rate of recovery of gold, silver and bronze is high, and synthetical recovery cost is little.
