Description
One. technical field
The present invention relates to metallurgy industry, particularly reclaim the technique of valuable metal in a kind of Copper making process, is the technique of a kind of Copper making spent acid and white flue dust synthetical recovery specifically.
Two. background technology
Usually containing valuable metals such as a certain amount of rhenium, bismuth, lead, zinc in copper ore concentrates.In Copper making process, the metal such as rhenium, bismuth is volatilized, enter in flue gas, rhenium is mainly enriched in spent acid, and bismuth, lead, zinc are mainly enriched in white flue dust, because the acidity of spent acid is higher, complicated component, the detrimental impurity content such as arsenic are high, and the content of the valuable metal ions such as rhenium (about 10mg/L), bismuth is lower, cause valuable metal recovery difficulty.At present, solvent extration, ion exchange method and chemical precipitation method is mainly contained from the technique of Copper making spent acid extraction rhenium.Spent acid Solvent Extraction of Rhenium because of impurity element in spent acid many, large to extraction interference, the rate of recovery is not high, and Solvent quantity is large, and flow process is loaded down with trivial details, complicated operation, and organism volatilization and abstraction waste liquor easily cause secondary pollution.Utilize ion-exchange directly to carry rhenium from spent acid, mainly there is the not high deficiency of selectivity.Chemical precipitation method is mainly Sodium Sulphide precipitation, Sodium Sulphide activity by force can not selective extraction rhenium, heavy metal especially copper, arsenic, antimony, bismuth etc. is separated out with rhenium simultaneously, because arsenic in spent acid, copper content are tens times of rhenium content even hundred times, Shang Qianbei, Sodium Sulphide precipitation rhenium is difficult to effective enriching rhenium, in throw out, rhenium content is lower than 0.1%, and reclaim further and produce rhenium product difficulty very greatly, the rate of recovery is also very low.Zhou Songlin etc. (CN 102628110 B) propose utilize Sulfothiorine to precipitate rhenium from spent acid, although the rhenium content in precipitation slag can reach about 10%, the arsenic content in precipitation slag is still higher, have up to 20%, the recovery of follow-up rhenium is still more difficult.At present, most of copper smelting plant still adopts sulfurization-precipitation method from spent acid, precipitate rhenium and arsenic, obtains arsenic filter cake, and sale at low prices processes to there being the producer of qualification.
The treatment process of white flue dust, the pyrometallurgical smelting technique that adopts reclaimed the valuable metals such as lead, bismuth more in the past.But traditional thermal process exists the shortcomings such as environmental pollution is serious, labor condition is poor, valuable element level of comprehensive utilization is low, the treatment process of white flue dust is gradually to wet method, wet method-pyrogenic process associating or selecting smelting combination technological development.Domestic and international copper smelting plant and some scientific researches, designing unit's dialogue dust treatment technique have all carried out large quantifier elimination, have explored many methods, but strictly speaking, have not still had one can realize industrial Perfected process so far.At present, because the arsenic content in white flue dust is higher, white flue dust sale at low prices processes to there being the producer of qualification by most copper smelting plant.
Three. summary of the invention
The object of the invention is the deficiency overcoming existing technique, the technique of a kind of Copper making spent acid and white flue dust synthetical recovery is provided, adopts the method, can rhenium in high efficiency separation waste acid recovery, spent acid can be made full use of and leach white flue dust, a set of copper can be utilized to reclaim and arsenic innoxious system synthesis process spent acid and white flue dust leach liquor, and process matching is good, and valuable metal comprehensive recovery is high, good waste water treatment effect, less investment, production cost is low, good in economic efficiency.
