Abstract
The present invention relates to a method of producing electrolytic copper by the germ soaking process of a sulfide mineral. The method of producing electrolytic copper by the germ soaking process of a sulfide mineral is characterized in that the crushed sulfide copper mineral enters a storage yard, the mineral is sprayed by sulfuric acid solution comprising germs, the germ soaking process is carried out, after the liquid comprising copper after the soaking process is collected and clarified, extraction is carried out by a copper extracting agent, and after the process of inverse extraction and an enriching process, the electrolytic copper is obtained after an electrically deposited technology. Compared with the prior art, the method of producing electrolytic copper by the germ soaking process of a sulfide mineral has the advantages that mineral resources can be fully utilized, the wet method smelting technique of the copper can be deepened and developed, the production cost of the copper is reduced, and the method of producing electrolytic copper by the germ soaking process of a sulfide mineral also has good economical and social benefits.
Description
The present invention relates to metallurgical technology field, specifically the method for producing electrolytic copper from germ soaking of sulfide mineral.
Leaching-the extraction of cupric oxide ore-electrodeposition technology entered since the nineties, and it is more and more faster to apply speed, and the silicic acid type cupric oxide ore that particularly acid consumption is lower is produced electrolytic copper, better economic benefit through the wet method gold process.But copper oxide ore resource is fewer and feweri, and has entered and contain 10% to 50% sulphide ores in the ore of acidleach factory and can't moltenly soak, and can not make full use of ore resource, and many wet method electrolysis copper work successively is faced with the crisis of resource problem.
The purpose of this invention is to provide a kind of economy and effective means, the molten leaching of sulphide ores in the ore is come, extract under certain condition-electrodeposition, production high-quality electrolytic copper, the sulphide ores bacterium that can make full use of ore resource is leached the method for production high-quality electrolytic copper.
The present invention is achieved in that the copper-sulphide ores after the fragmentation entered the heap field boundary, with the sulphuric acid soln that contains bacterium ore sprayed, and carries out that bacterium is molten to be soaked, after cupric liquid collecting after molten the soaking, the clarification, utilize the copper extractant extraction, back extraction, after the enrichment, behind electrodeposition process, get the 1# electrolytic copper.
Spray solution sulfur acid 0.5-0.7%, ferric ion 0.5-0.7%, water 98-99%, solution contain every milliliter 10 on bacterium
7-10
9Individual, walk abreast into that spray is molten to be soaked, extract, the working cycle of bacteriological aftergrowth, used bacterial classification and regenerated bacteria are thiobacillus (Thio-bacillus spp.)
Copper extractant is that No. 200 kerosene dilutions of 10%Lix984 adding 90% form.
Extraction, back extraction and poor organic phase pond are a recycle system, and filtrate is carried out continuously and extraction repeatedly.
The present invention is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a process flow sheet of the present invention
Embodiment after 200 tons of copper-sulphide ores (can be copper glance, chalcopyrite and purple copper) fragmentation, enters the heap field boundary with it, uses sulfur acid 0.5%, ferric ion 0.7%, water 98.8%, presses every milliliter 10
7-10
9The sulphuric acid soln that the ratio of individual bacterium adds sprays ore, carry out that bacterium is molten to be soaked, after the cupric liquid collecting after molten the soaking, the clarification, utilize 10%Lix984 to add the copper extractant extraction that 90% No. 200 kerosene dilutions form, and form that spray is molten to be soaked, extract, the working cycle of bacteriological aftergrowth.The bacterium of used bacterial classification and molten leaching is thiobacillus (Thio-bacillus spp.).And extract, back extraction and poor organic phase pond be a recycle system, and filtrate is carried out continuously and extraction repeatedly, be beneficial to remove and abandon impurity and enriching Cu ion.Back extraction, enrichment, electrodeposition and electric tail washings pond form the another shape loop systems of following.After the enrichment (＞35g/l) behind electrodeposition process, 1# electrolytic copper product.
Method of the present invention compared with prior art has can make full use of ore resource, makes the wet process smelting technique of copper obtain in-depth and development, has reduced the production cost of copper, and favorable economic benefit and social benefit are arranged.It is concrete that relatively index is as follows:
1, half industrial experiment technical indicator:
1. ore property analysis: this ore is fine and close, hard, is the silicate mixed ore.Grade 0.965%, in conjunction with cupric oxide 0.117%, free cupric oxide accounts for 0.145%, oxidation ratio 27.15%, grade distributes :-20mm accounts for 100%, and-15mm accounts for 97.5%, and-12mm accounts for 82.32%, and-5mm accounts for 16.17%.
2. index: extraction time 171 days, leaching yield 69.88%, acid consumption 6.73t/tCu, 17936.89 yuan/tCu of comprehensive cost has favorable economic benefit.
2, contrast table
| Sequence number | Condition | Extraction time (my god) | Leaching yield (%) |
| 1 | 200 gram ore+rare H2SO 4(15g／l)800ml | 67 | 16．65 |
