Description
Technical Field
The utility model relates to a non ferrous metal smelting technical field, in particular to contain arsenic danger waste residue processing apparatus.
Background
Copper in ore fines used in pyrometallurgical copper smelting generally exists in the form of copper sulfides, arsenic is associated with copper mainly in the form of tennantite (3Cu2s. as2s3) and enargite (Cu3AsS4), arsenic-containing minerals are substantially insoluble in water and occur in copper concentrates during the mining and dressing process, in the smelting process, arsenic in copper concentrate is gasified and enters smelting flue gas basically and exists in the form of As2O3, flue gas generated by the pyrometallurgical copper smelting is required to be purified to produce industrial finished sulfuric acid, most enterprises for purifying the flue gas and removing arsenic and heavy metals adopt an iron salt method and electrocoagulation combined arsenic removal process, the process enables arsenic in the waste acid to generate calcium arsenite, calcium arsenate and calcium fluoride, the calcium arsenite, the calcium fluoride and the heavy metal are precipitated together, further arsenic ions in the sewage are removed by methods such as electric flocculation, membrane filtration, resin filtration and the like, the treated water reaches the GB25467-2010 standard and then is recycled in a closed loop in a production workshop, and the treatment process is proved by production practices: the method is characterized by saving investment, low operating cost and ideal treatment result, is one of effective treatment processes, but generates a large amount of sludge, a 10-ton copper production device is used, 19470 tons of arsenic-containing dangerous waste residues are produced annually, water content is 45 percent, 28000 tons of arsenic-containing dangerous waste residues are produced annually, the arsenic residues contain other heavy metal salts besides 3.5 to 4 percent of arsenic, secondary pollution is easy to form, sodium sulfide is used for dearsenization, dearsenization can reach more than 98.5 percent, arsenic-containing dangerous waste residues are also produced, and if the device is used for producing 10 ten thousand copper annually, 4100 tons/year of high-arsenic-containing dangerous waste residues are produced; reprocessing is also required; thirdly, the method comprises the following steps: the method adopts a hydrogen sulfide method, is similar to a sodium sulfide method in process, only adopts ammonia to prepare hydrogen sulfide by self, then uses hydrogen sulfide to react with arsenic acid, and filters to obtain arsenic-containing slag, the amount of the arsenic-containing slag obtained by the method is almost the same as that obtained by the sodium sulfide method, the production cost is slightly lower than that obtained by the sodium sulfide method, 10 ten thousand copper annual products generate more than 4100 tons of dangerous waste slag, and the three methods for treating arsenic-containing wastewater all generate arsenic-containing dangerous waste slag and all need to carry out secondary dangerous waste slag treatment.
