Description
Technical field
The present invention relates to a kind of method of hydrometallurgical recovery manganese, specifically a kind of method of spessartine ore wet process metallurgy.
Background technology
Spessartine is that land resources department thinks and there is no at present the silicate minerals of industrial significance or the little manganese of industrial significance.Adopt pyrometallurgy from spessartine ore deposit, to reclaim that the method recovering effect of manganese is poor, cost recovery is high; Conventional wet metallurgy can not effectively extract manganese.
Spessartine is a kind of end member of blythite class, and its structure expression is: Mn
3al
2(SiO
4)
3, the silicate minerals, the symmetry that belong to tesseral system island structure are strong, and crystalline structure is stable, has chemical bonded refractory between very strong atom and makes a concerted effort, and Brinell hardness is 6.5～7.The good spessartine crystal of crystal habit can be used as a kind of jewel of viewing and admiring, and has higher ornamental value.Spessartine is widely distributed, in the manganese ore of all parts of the world, all exists, and it is by the mineral of siliceous, aluminium, manganese and other element, naturally to be synthesized under high temperature at Earth, condition of high voltage, with earth movement, rises to earth's crust shallow-layer or earth's surface.In manganese resource, extensively and the common association of manganese mineral such as manganese carbonate ore, manganese oxide ore, in part ore body, spessartine accounts for 60～70% of manganese-bearing mineral total amount to spessartine mineral, is a kind of important manganese resource.But because the crystalline structure of spessartine is stable, extremely difficult destruction.The theoretical manganese content of spessartine minal only has 33.29%, and the elements such as aluminium, silicon are present among spessartine mineral lattice, can not it is separated with main manganese metal by traditional ore dressing process.In industrial practice, how simple spessartine mineral or take that it need to be destroyed with the high temperature of pyrometallurgical processes as main mineral, coordinates with other manganese mineral and is used for pyrogenic process production silicomanganese.But due to the too high levels of silicon, aluminium wherein, smelt the silicomanganese of output and can not directly as commodity silicomanganese, sell and use, only can use as the primary raw materials of further smelting.Therefore, at China's Geological And Mineral Resources Departments In Their, list in and there is more than 20 of industrial significance and plant in manganese mineral, do not comprise the silicate-blythite that there is no at present industrial significance or the little manganese of industrial significance.Because conventional wet metallurgical process cannot effectively be decomposed spessartine extraction manganese element wherein, there is not yet the report that adopts Wet-process metallurgy method to process spessartine mineral.The manganese hydrometallurgy factory and the manganese factory that at present adopt traditional technology directly to leach manganese ore, generally all using manganese carbonate ore and manganese oxide ore to produce as raw material.In manganese mineral raw material as contain higher spessartine, the leaching yield of manganese will be had a strong impact on, so each mine there is a large amount of spessartine ore deposits and cannot effectively applies.These ore manganese contents of storing up are higher only 20% left and right, both cannot meet the ingredient requirement of pyrogenic attack, can not use hydrometallurgical process.China is maximum in the world manganese country of consumption, and manganese ore output far can not be satisfied the demand, and also wants a large amount of import ANOMALY IN FINE QUALITY MANGANESE DEPOSITS to meet need of production.Though there is the manganese resource compared with horn of plenty in China, take medium and small mineral deposit as main, and ore grade is lower.Existing spessartine mineral are fully utilized, by the contradiction greatly solving between manganese consumers demand and supply, meet the demand of the national economic development.
Summary of the invention
For the not treatable spessartine mineral wealth of conventional wet technique are effectively utilized, the present invention proposes a kind of technical scheme of method of spessartine ore wet process metallurgy.
Technical scheme of the present invention is: a kind of method of spessartine ore wet process metallurgy, and the technology of employing hydrometallurgy, contained manganese in leaching spessartine mineral, with other component separating in mineral, concrete steps are:
(1) mineral pulverizing, levigate to below-100 orders;
(2) at spessartine mineral, add water furnishing ore pulp, the water weight adding is 3～7 times of mineral weight;
(3) in ore pulp, add sulfuric acid, slurry preparing to acid concentration is 20g/L～200g/L;
(4) heating ore pulp, insulation leaching;
(5) liquid-solid separation, obtains containing manganese leach liquor.
What step (3) was described adds sulfuric acid for once all adding or adopting pump that ore pulp is added continuously in ore pulp, and realization is worked continuously.
The temperature in the described heating of step (4) ore deposit is 90 ℃～220 ℃, and the time of described insulation leaching is 60min～300min, and the process of leaching completes in closed reaction vessel.
The liquid-solid separation that step (5) is described, obtaining containing manganese leach liquor is to adopt to filter to carry out separation, or supernatant realizes liquid-solid separation.
The present invention is from spessartine, the method strengthening reaction process of the operating pressure in employing raising closed reactor and temperature, High-Temperature Strengthening acidleach makes manganese in manganese raw material rapidly, fully leach, and effectively separated with the gangue component such as silicon, aluminium, makes leaching yield and cost reach best.Because the crystalline structure of spessartine is stable, extremely difficult destruction, the element such as aluminium, silicon is present among spessartine mineral lattice, the present invention is by spessartine mineral pulverizing, levigate, furnishing ore pulp, add sulfuric acid, the temperature and the leaching time that compared with ordinary method, have improved heating ore pulp, adopt the method for filtration or supernatant to carry out liquid-solid separation, obtains meeting containing manganese the leach liquor that subsequent handling requires.
The present invention adopts pressurized acid leaching method to leach from spessartine ore deposit and reclaims manganese, by pressurized acid leaching, greatly strengthens Leaching reaction condition, destroys mineral structure, directly soaks the manganese in molten spessartine ore deposit.Spessartine ore wet process metallurgical method of the present invention can extract most manganese in mineral, and present method production efficiency is high, free from environmental pollution.
The beneficial effect of the invention is: the direct manganese in leaching of manganese pyralspite ore deposit, be conducive to improve the utilization ratio of manganese resource, and expanded the raw mineral materials kind of manganese hydrometallurgy; By strengthening reaction conditions, the spessartine mineral failure that existing Wet-process metallurgy method cannot be decomposed decomposes, extract wherein contained manganese, realize the molten manganese with reclaiming wherein of soaking of spessartine ore deposit, adopt method of the present invention can under the condition of less expensive, effectively extract the manganese in spessartine mineral, improve the utilization ratio of manganese resource; The calorific loss that large quantity of moisture evaporation brings in leaching process of having avoided when operation is carried out in closed container heating, avoid the reactant gases of overflowing in operation process and acid mist pollution environment and the harm to operator, improve operating condition; simultaneously Technique of the present invention possesses skills advanced, easy to operate, and resource utilization is high, and manganese leaching yield is high, and the activity duration is short, and technical process is short, and labour productivity is high, eco-friendly feature.
