Abstract
The concentrated acid curing of the molybdenum nickel minerals in a kind of chemical industry metallurgical field leaches depolymerization solvent extraction technology method.Ripe soaking with unique depolymerization, extraction phase bonded separation method carried out very high with separating acquisition fast effectively economic and technical norms and benefit to molybdenum nickel thereby method adopts the vitriol oil efficiently.
Molybdenum in products obtained therefrom ammonium molybdate or the molybdic oxide can be used for the interpolation element of various high-grade alloy steels, the trace element that farm crop and human body need; Nickel ammonium sulfate can be used as the raw material of steel alloy and magneticsubstance, is used for analytical reagent and electroplating industry.
Description
The concentrated acid curing that the present invention relates to a kind of molybdenum-nickel paragenetic ore deposit in chemical industry metallurgical field leaches depolymerization solvent extraction technology method.It comprises following several steps: with the broken mill of molybdenum nickel minerals, roasting, extraction, reextraction, acidifying, concentrated, purification.
In the prior art, have only the single technology of carrying molybdenum from concentrated molybdenum ore abroad, and directly extract the advanced method of molybdenum nickel metal in the molybdenum-nickel paragenetic ore deposit of having no way of.Be exactly in the treatment process of concentrated molybdenum ore, both at home and abroad in order to improve the rate of recovery of molybdenum to greatest extent, although adopted high temperature, high pressure, oxygen to press reinforcement means such as boiling electrooxidation, owing to be subjected to the restriction of ore dressing yield, the smelting total yield that selects of molybdenum also can only reach about 90%.The for example Ford of U.S.'s Hawkeye State, Madison factory, molybdenum concentrate grade＞59%, processing method is that hyperbaric oxygen soaks extraction or ion-exchange flow process, it is 90% that molybdenum selects the smelting total yield; The Ma Gena factory of Utah, USA, the molybdenum grade is 35.6%, and processing method is that electrooxidation-solvent extraction-charcoal absorption-crystallization is separated out, and it is 90% that molybdenum selects the smelting total yield; Soviet Union Uzbekistan infusibility hot metal company, molybdenum concentrate grade＞47%, method adopts High Temperature High Pressure digestion, solvent extraction, and molybdenum selects smelting total yield about 90%.Though domestic units concerned have done a large amount of experimental studies to this molybdenum nickel minerals, all fail to break away from traditional solvay soda process, this method handle its weak point of molybdenum-nickel paragenetic ore deposit be that the rate of recovery is low, cost is high, of poor benefits.Molybdenum can only reclaim 60～70%, and big of nickel or all can not reclaim causes the national resources waste big.For example this molybdenum-nickel paragenetic ore deposit is handled in Kunming Metallurgy Inst's research, and method adopts alkali method process, and the grade of molybdenum is 6～7%, and the grade of nickel is 3.0～3.5%, and the rate of recovery of molybdenum only is 60%, and nickel all can not reclaim.
The objective of the invention is to avoid the deficiencies in the prior art part, a kind of concentrated acid curing efficient, economic, molybdenum-nickel paragenetic ore deposit fast leaches, depolymerization solvent extraction novel process and provide.So that replace the alkali method process that falls behind at present, to guarantee obtaining maximum economic benefits and fully rationally utilizing in the smelting to national resources.
Purpose of the present invention can reach by following measure, with the broken mill of molybdenum nickel minerals, roasting, extraction, reextraction, acidifying, condensing crystal, purification.
Purpose of the present invention can also reach by following measure: carry out slaking and leach after broken mill, roasting with the molybdenum nickel minerals, the depolymerization extracting and separating is then with gained raffinate condensing crystal.
The present invention has following advantage compared to existing technology:
1, use the present invention, ore need not pass through ore dressing, and directly makes molybdenum nickel product by raw ore.
2, economic and technical norms height.The rate of recovery, cost and profit norm are not only gone together considerably beyond domestic, and the index of molybdenum and external advanced molybdenum producer are more not inferior yet, and the industrial chemicals of Tou Ruing can also be converted into and pay a product and obtain partially recycled simultaneously.
3, use flow process of the present invention simultaneously high target obtain two kinds of products of molybdenum nickel, do not need the processing nickel that constructs the factory buildings in addition, this is that existing other technical process is incomparable.
4, use technical process of the present invention, the molybdenum grade is 6～7% in the raw ore, and the nickel grade is 3.0～3.5%, and molybdenum recovery reaches 95%, and nickel recovery reaches 70%.
5, the present invention has considered comprehensive improvement, and the three wastes are few, pollution is few.
The drawing of accompanying drawing is described as follows:
This figure is a technological process block-diagram of the present invention, wherein 1 for raw ore, 2 for broken mill, 3 for roasting, 4 for slaking leach, 5 for depolymerization, 6 and 11 for molybdic acid, 7 and 14 for extraction, 8 and 15 for back extraction, 9 for acidifying, 10 and 17 has for poor, 12 for mother liquor, 13 for ammonium molybdate or molybdic oxide, 16 for anti-stripping agent, 18 and 20 for concentrate, 19 for nickel ammonium sulfate, 21 for ferric ammonium sulfate, 22 for waste liquid, 23 for waste gas, 25 for emptying, 24 for purification, 26 for discarding.
The present invention is described in further detail below in conjunction with drawings and Examples: be milled to-200 orders and account for 56% raw ore is broken, 530 ℃～570 ℃ following oxidizing roastings 2.5 hours, with vitriol oil slaking 2～3 hours under heating, add water 85 ℃ of following agitation leachs 1.5 hours, separate with the ammoniacal liquor depolymerization again, pH value is controlled at 0.5～0.8, obtains most of molybdenum.Remaining molybdenum 0.1MR in mother liquid obtained
3The agent of N+7%TBP+ kerosene extraction extracts.Raffinate is used P again
204The extraction deironing, gained raffinate reconcentration, crystallization promptly get nickel ammonium sulfate.Above-mentioned depolymerization and extract molybdic acid further produce ammonium molybdate or molybdic oxide again.
