Description
Technical field
The present invention relates to a kind of integrated conduct method of nonferrous metallurgical process solid waste, is particularly selecting smelting combination from copper smelting
The method for refining comprehensively recovering valuable metal in cigarette ash.
Background technology
Contain a variety of valuable metals such as Cu, Fe, As, Pb, Zn, Bi, grade in a large amount of cigarette ashes produced during Copper making
Higher than general ore, there is very high comprehensive utilization value, the comprehensive reutilization of its valuable metal is constantly subjected to extensive concern.
Common method has alkaline leaching, acidic leaching and the wet method combined method of pyrogenic process etc..
Since during Copper making, most of cigarette ash Returning smelting systems, outer row is just considered as Pb, As higher, therefore
Outer discharge capacity is smaller, is adapted to wet processing process.Wherein it is most widely used with sulfuric acid leaching, Hou Xin is just waited (from copper converter cigarette
Copper, zinc experimental study hydrometallurgys, 2011,30 (1) are leached in ash:Sulfuric acid leaching ash of copper converter 57-59.) is used,
1.80 mol/L of sulfuric acid concentration, liquid-solid ratio 7:1st, 1.5 h are leached under the conditions of 70 DEG C of extraction temperature, the leaching rate of Cu, Zn are up to 90
More than %, Fe, Pb then enter in slag, and the method technique is simple, environmental pollution is small is beneficial to environmental protection；The drawback is that liquid-solid ratio is excessive, leaches
Liquid metal concentration is low and Pb and Fe does not obtain further separation and concentration.(Copper smelting dust sulfuric acid leaching and copper are leached and moved Sun Ledong etc.
Mechanics study mining metallurgical engineerings, 2016,36 (1):It 97-100.) have studied the power credit of sulfuric acid leaching Copper smelting dust process
Analysis, the results showed that sulfuric acid leaching process belongs to diffusion control, and the apparent activation energy of Leach reaction Cu is 8.05 kJ/mol, therefore can
Strengthen diffusion control effect by improving the means such as liquid-solid ratio, mixing speed.Zhang Xiaofeng etc. (is roasted and copper in high arsenic white cigarette ash is soaked
The influence of extracting rate and its thermodynamic analysis mining metallurgical engineerings, 2012,32 (5):86-89.) have studied white cigarette ash roasting transition-
Acidleach thermodynamics, the results showed that, the copper sulfide of slightly solubility and cuprous oxide can be converted into ease of solubility copper by roasting, be greatly enhanced
The leaching rate of copper, explains the reason for copper leaching rate during direct acidleach is not high, but roasts in transformation process that there are arsenic
Vaporization behaviors, are unfavorable for environmental protection.Patent application 200910080464.7,201410690393.3,201510693277.1,
201610030159.7 etc. disclose the method that sulfuric acid system leaches Bellamya aeruginosa, realize the leaching of good valuable element,
But these method common ground are all that technological process is long, Steep cencentration is low, are also easy to produce " three wastes ".
Experimental study finds, the atrament for being about 20% containing mass percent in Copper making cigarette ash, through assay,
This material contains a large amount of Armco magnetic irons and a small amount of copper, has stronger magnetism.For this reason, the present invention using magnetic selection method to cigarette ash into
Row pretreatment, isolates most of atrament, reduce it is neutral leach cigarette ash treating capacity, in raising in immersion liquid arsenic content,
Contribute to SO2The heavy arsenic of reduction, while reduce the influence that iron filters acidleach, the acidity of acidleach can be greatly improved, reduces acidleach
Arsenic content in slag, and rich scum, high lead bismuth slag and high purity copper are can obtain, realize the synthetical recovery of valuable metal, there is technique
Simply, the features such as selectivity is good, without " three wastes " discharge, economy and obvious environment benefit, has good promotional value.
