Description

A kind of pretreatment process of copper anode mud
Technical field the present invention relates to hydrometallurgy process in the field of metallurgy, particularly the Wet-process metallurgy method of pre-treatment copper anode mud effectively.
The background technology copper anode mud is the product of blister copper electrorefining process, mainly contains metals such as gold and silver, platinum metals, copper, selenium, tellurium, arsenic, antimony, bismuth, lead, nickel, is the important source material of extracting precious metal.In order to extract the precious metal in the copper anode mud, need other earlier that content is high than precious metal base metal to separate and recovery, promptly before extracting precious metal, copper anode mud is carried out pre-treatment, remove, and then extract Jin Heyin with pyrogenic process or wet method to the big foreign metal of precious metal leaching process influence.
No matter be from copper anode mud, to extract precious metal with pyrogenic process or wet method, influencing bigger foreign metal mainly is arsenic, selenium, copper and tellurium etc., pretreated purpose is to remove these metals from copper anode mud, its major cause is: the one, and copper anode mud is in the pyrometallurgical smelting process, precious metal easily forms sulfonium mutually with selenium, tellurium and copper etc., causes precious metal to disperse, and the metal direct yield is low, arsenic is dispersed in each intermediate product in follow-up pyrogenic attack process in addition, has strengthened and has focused on difficulty; The 2nd, precious metals containing lead cupric, selenium and tellurium make the converting process lengthening when contour, and reagent consumption increase, energy consumption increase; The 3rd, copper, selenium, tellurium and arsenic etc. form intermetallic compound with precious metal in the copper anode mud, cause precious metal dissolving weak effect in the wet processing process, and the precious metal direct yield is low; The 4th, arsenic, selenium, copper and tellurium etc. easily enter the gold and silver purification process, influence the gold and silver quality product; So, no matter be with the precious metal in pyrogenic process or the wet method extraction copper anode mud, must remove these foreign metals in advance, to improve the precious metal rate of recovery, shorten treating processes, to improve the gold and silver quality product.
The research of the pretreatment process of relevant copper anode mud is a lot, mainly contain methods such as atmospheric oxidation decopper(ing) method, oxidizing roasting method, sulfurization roasting method, soda roasting method, sulfuric acid system pressure oxidation leaching-out method, beneficiation enrichment method, at present three kinds of sulfating roasting method, pressure oxidation acidleach method and beneficiation enrichment methods are arranged at the pretreatment process of industrial extensive employing.
The sulfating roasting method is that copper anode mud is mixed the back at the revolution roasting in kilns with the vitriol oil, makes selenolite change into volatile SeO 2And reclaim with the form of thick selenium, copper changes into the copper sulfate of solubility, uses the diluted acid dissolved copper again; This method has that maturing temperature is low, selenium and copper decreasing ratio advantages of higher, but the shortcoming that exists is that equipment corrosion is fast, aided process long, environmental pollution is serious, the arsenic scattering problem is outstanding.Pressure oxidation acidleach method is to adopt the mode of High Temperature High Pressure to strengthen the decopper(ing) reaction process at sulfuric acid system, and the leaching yield of this method copper reaches more than 98%, is attended by the dissolving of metals such as a spot of silver, selenium, tellurium, arsenic simultaneously; The advantage of this method is that copper decreasing ratio height, technological process are short, but has shortcomings such as equipment is perishable, the selen-tellurjum decreasing ratio is low, the arsenic scattering problem is outstanding.Floating and enriching method is that flotation was handled after copper anode mud adopted the atmospheric oxidation decopper(ing), base metals such as most of lead, antimony are separated with precious metal, gold and silver, selenium, tellurium and platinum metals etc. are enriched in the silver preparation concentrate, the silver preparation concentrate argentiferous that obtains reaches more than 50%, normal combining with copper anode mud pyrogenic attack process of this method is called selecting smelting combination technology, adopts roasting method to make selenium with tin anhydride volatilization recovery before retailoring again; This method have concentration of precious metal than high, technological process short, low cost and other advantages, but drawbacks limit such as big, the comprehensive recovering effect difference of its wastewater flow rate the popularization of this method.
Summary of the invention the purpose of this invention is to provide a kind of copper anode mud of pre-treatment effectively and removes arsenic, selenium, tellurium and copper, and the free of contamination Wet-process metallurgy method of process.
The technical solution used in the present invention is in order to achieve the above object: after screening of copper anode mud process and the hot wash, carrying out pressure oxidation in alkaline hydrogen sodium oxide system leaches, selenium and arsenic is oxidized to enter alkaline leach liquor, copper and tellurium be oxidized to enter alkaline leached mud, the alkalescence leached mud leaches copper and tellurium with sulphuric acid soln again, and concentration of precious metal is at acid leached mud.
