Description
Technical field
The present invention relates to a kind of flotation and metallurgy method of copper mine, belong to ore dressing and metallurgical technology field.
Background technology
The oxygenation efficiency that mixed copper ore refers to copper is at a class Copper Ores of 30 ~ 70%.Mixed copper ore processing method roughly has following a few class: (1) floatation, comprise sulfide flotation method, fatty acid collecting agent direct flotation and amine collector floatation, what generally apply at present is sulfide flotation method, the main development of sulfide flotation method is collecting agent, particularly the mixing of collecting agent is used, taking xanthate class as main, coordinate chelate collectors or carboxylic acids collecting agent, can obviously improve flotation recovery rate.(2) choosing-smelting combination method, adopts conventional sulphide ore beneficiation method, adds xanthate and terpenic oil flotation, and to reclaim copper sulfide mineral, flotation tailing adds Ore Leaching again and reclaims copper oxide mineral; In flowage structure, the choosing-smelting process that adopts first flotation to leach again in industrial production is commonplace, and adopts the technique of the first rear flotation of leaching more rare; For example Chinese patent CN101961673A has reported a kind of selecting smelting combination method of mixed copper ore, mixing ore deposit for oxygenation efficiency between 10 ~ 80%, select sulphide ore by floatation and obtain copper concentrate, flotation tailing directly carries out acidleach leaching again, pickle liquor obtains tough cathode through extraction electrodeposition, and the method significantly improves the rate of recovery in oxysulphied ore deposit; Segregation-floatation commercial Application comparative maturity, but require mixed copper ore grade higher (being conventionally greater than 2%), production run cost is high, and in addition, the choosing-metallurgical methods such as pressure ammonia leaching sulfide precipitation-floatation, hydro-thermal vulcanizing-flotation method are all in the laboratory research stage.(3) direct leaching, comprises the acid-hatching of young eggs, ammonia leaching process and Bioleaching method; For the silicate gangue-type ore deposit of high oxidation rate, the acid-hatching of young eggs is used commonplace, and for carbonate gangue-type ore deposit, conventionally adopts alkaline leaching.
For the mixing ore deposit of oxygenation efficiency high (50 ~ 70%), floatation only can reclaim copper sulfide mineral and partial oxidation Copper Processing Industry mineral; And employing lixiviation process, copper sulfide mineral cannot reclaim, financial cost is high, environmental pressure is large, especially to carbonate gangue content high mixing ore deposit, directly picking acid consumption is high, cost is high; Choosing-smelting combination method can improve comprehensive recovery, and saves to a certain extent financial cost and alleviate environmental pollution, is to process at present the more promising method of such ore; For the high mixing ore deposit of carbonate gangue content, in sulfide flotation mine tailing, carbonate gangue content is still higher, takes preprocess method to reduce carbonate gangue content, is the important channel that reduces acidleach cost.
Carbonate-type gangue mixed copper ore, carbonate gangue content is high, and flotation tailing directly leaches, and acid consumption is high, cost is high, acid system is metallurgical is difficult to carry out.Chinese patent CN101831559A has reported a kind of choosing-metallurgical method of high-bonding-ratio carbonate gangue-type mixed copper ore, adopts aliphatic acid reverse flotation to remove calcium carbonate and magnesium carbonate gangue, then add sulfuric acid leaching, Recovering Copper to mine tailing after flotation.Flotation tailing removes the carbonate gangue that consumption is sour in advance, can create favorable conditions in mixed copper ore comprehensive utilization for choosing-smelting method to a certain extent.The deficiencies such as but reverse flotation removes carbonate gangue has that collecting agent poor selectivity, decarburization hydrochlorate effect are not ideal enough, integrated artistic flow process complexity, floating agent cost are high, reverse flotation cycling utilization of wastewater complexity.
Summary of the invention
A kind of method that the object of the invention is to propose economy, simply and efficiently reclaims mixed copper ore.Mixed copper ore of the present invention is Cu grade 0.20 ~ 3.00%, the oxygenation efficiency 15 ~ 75% of copper, and wherein in conjunction with cupric oxide occupation rate 2.00 ~ 20.00%, the copper mineral of CaO content 6 ~ 20%.
The present invention is achieved through the following technical solutions:
1. flotation: ore grinding accounts for 60 ~ 80% to-0.075mm, by ore quality, adds Na
2s 500 ~ 1200g/t, butyl xanthate 100 ~ 1000g/t, terpenic oil 25 ~ 100g/t, obtains copper concentrate and flotation tailing;
2. magnetic separation: magnetic separation flotation tailing under magnetic field intensity 0.35 ~ 1.30T, obtains magnetic concentrate and magnetic tailing;
3. dehydration is leached: magnetic concentrate thickening, to liquid-solid ratio 2 ~ 3:1, is added the concentrated sulfuric acid to pH=1, leaching 20 ~ 60 minutes, and Separation of Solid and Liquid obtains leachate and leached mud, and hydrometallurgical process leachate, obtains tough cathode.
Technical scheme of the present invention accounts for 60 ~ 80%, copper sulfide mineral degree of dissociation approximately 75 ~ 90%, copper oxide mineral degree of dissociation 70 ~ 85% by raw ore ore grinding to-0.075mm; After flotation, the Cu Concentrate Grade obtaining is 15 ~ 23%, the rate of recovery 40 ~ 50%; The flotation tailing obtaining is mainly not sulfide flotation recovery
-?2?-
Cupric oxide and carbonate (being mainly calcite) gangue mineral etc., containing Cu 0.15 ~ 1.00%, CaO 8.00 ~ 15.00%, magnetic tailing after magnetic separation is containing Cu 0.20 ~ 2.00%, CaO 10 ~ 30.00%, copper loss late 5 ~ 30%, CaO removal efficiency 40.00 ~ 80.00%; Magnetic concentrate is containing Cu 0.50 ~ 3.00%, CaO 3.00 ~ 10.00%, copper recovery 30 ~ 60%, the CaO rate of recovery 20.00 ~ 60.00%; Copper obtains certain enrichment in magnetic concentrate, and most of carbonate gangue is thrown in magnetic tailing.
The copper of mixed copper ore 30 ~ 40% is composed and is stored in the mineral such as limonite, psilomelane, sericite, chlorite, because these ores itself have magnetic, or lattice is replaced, parcel is carried ferromagnetic mineral secretly and had weak magnetic; The carbonate such as calcite, dolomite consumes sour gangue mineral does not have magnetic, and composes the copper content that is stored in carbonate gangue and be less than 2%, therefore adopts magnetic separation to throw except most of carbonate gangue is in magnetic tailing.Throw except most of carbonate gangue by magnetic separation, the copper in last magnetic concentrate obtains enrichment to a certain degree.
The advantage of technical solution of the present invention is as follows:
1. the cupric oxide industrial mineral of the good copper sulfide mineral of pair floatability and easy sulfide flotation adopts sulfide flotation method cheaply, technological process simple possible, and stable operation is reliable.
2. application magnetic concentration copper is in magnetic concentrate, throw except most of carbonate gangue is in magnetic tailing, compared with the aliphatic acid reverse flotation methods such as oleic acid, process stabilizing is simple, decarburization hydrochlorate gangue better effects if, magnetic concentration working backwater can all recycle, and does not use floating agent, and cost is low, pollution-free, energy-saving and environmental protection.The inventive method choosing-smelting associating, copper comprehensive recovery is higher, is a kind of method of Recovering Copper of simple, efficient, economic, energy-conservation and environmental protection.
