Description
Technical field
The present invention relates to a kind of method of hydrometallurgical recovery manganese, specifically is the metallurgical method of a kind of spessartine ore wet process.
Background technology
Spessartine is that land resources department thinks still do not have at present the silicate minerals of the little manganese of industrial significance or industrial significance.Adopt pyrometallurgy from the spessartine ore deposit, to reclaim poor, the cost recovery height of method recovering effect of manganese; Conventional wet metallurgy can not effectively extract manganese.
Spessartine is a kind of end member's mineral of blythite class, and its structure expression is: Mn
3Al
2(SiO
4)
3, the silicate minerals, the symmetry that belong to the tesseral system island structure are strong, and crystalline structure is stable, has between very strong atom chemical bonded refractory and makes a concerted effort, and HB is 6.5～7.Crystal habit spessartine crystal preferably can be used as a kind of jewel of viewing and admiring, and has higher ornamental value.Spessartine distributes extensively, in the manganese ore of all parts of the world, all exists, and it is synthetic naturally by the mineral of siliceous, aluminium, manganese and other element under the high temperature, condition of high voltage in deep Earth, and moving with the earth's crust rises to the earth's crust shallow-layer or the face of land.In manganese resource, the spessartine mineral extensively and the common associations of manganese mineral such as manganese carbonate ore, manganese oxide ore, spessartine accounts for 60～70% of manganese-bearing mineral total amount in the part ore body, 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 elements such as aluminium, silicon are present among the spessartine mineral lattice, can not it be separated with main manganese metal through traditional ore dressing process.In the industrial practice, simple spessartine mineral or be that master's mineral need destroy with the high temperature of pyrometallurgical processes with it, the many cooperation with other manganese mineral is used for pyrogenic process production silicomanganese.But, only can use as the primary raw materials of further smelting because the too high levels of silicon, aluminium is wherein smelted the silicomanganese of output and can not directly be sold as the commodity silicomanganese and use.Therefore, China Ministry of Geology and Mineral Resources door list in have industrial significance 20 surplus in kind of the manganese mineral, do not comprise the silicate-blythite that does not still have the little manganese of industrial significance or industrial significance at present.Extract manganese element wherein because the conventional wet metallurgical process can't effectively be decomposed spessartine, Shang Weijian has the report that adopts Wet-process metallurgy method to handle the spessartine mineral.The manganese hydrometallurgy factory and the manganese factory that adopt traditional technology directly to leach manganese ore at present generally all produce as raw material with manganese carbonate ore and manganese oxide ore.In the manganese mineral raw material as contain higher spessartine, with the leaching yield that has a strong impact on manganese, so there is a large amount of spessartine ore deposits in each mine and can't effectively uses.Higher only the having about 20% of these ore manganese contents of storing up both can't have been satisfied 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 satisfy the production needs.Though there is the manganese resource than horn of plenty in China, be main with medium and small mineral deposit, and ore grade is lower.Existing spessartine mineral are fully utilized,, satisfy the demand of the national economic development the contradiction that solves greatly between manganese consumers demand and the supply.
Summary of the invention
For the spessartine mineral wealth that conventional wet technology can not be handled effectively utilize, the present invention proposes the technical scheme of the metallurgical method of a kind of spessartine ore wet process.
Technical scheme of the present invention is: the method that a kind of spessartine ore wet process is metallurgical, and the technology of employing hydrometallurgy, contained manganese in the leaching spessartine mineral, with other component separating in the mineral, concrete steps are:
(1) mineral pulverizing, levigate to below-100 orders;
(2) add water furnishing ore pulp at the spessartine mineral, the water weight of adding is 3～7 times of mineral weight;
(3) in ore pulp, add sulfuric acid, ore pulp allocate to acid concentration be 20g/L～200g/L;
(4) heating ore pulp, insulation leaching;
(5) liquid-solid separation obtains containing the manganese leach liquor.
The described sulfuric acid that in ore pulp, adds of step (3) is realized working continuously for once all adding or adopting pump that ore pulp is added continuously.
The temperature in the said heating of step (4) ore deposit is 90 ℃～220 ℃, and the time of described insulation leaching is 60min～300min, and the process of leaching is accomplished in closed reaction vessel.
The described liquid-solid separation of step (5), obtaining containing the manganese leach liquor is to adopt to filter to separate, or the heavy clear liquid-solid separation that realizes.
The present invention is from the spessartine; Adopt the WP and the method for temperature that improve in the closed reactor to strengthen reaction process; The High-Temperature Strengthening acidleach makes rapid, the fully leaching of the manganese in the manganese raw material, and effectively separates with gangue components such as silicon, aluminium, makes leaching yield and cost reach best.Because the crystalline structure of spessartine is stable, extremely difficult destruction; Element such as aluminium, silicon is present among the spessartine mineral lattice, and the present invention is with spessartine mineral pulverizing, levigate, furnishing ore pulp; Add sulfuric acid; Improve temperature and the leaching time that heats ore pulp than ordinary method, adopted filtration or heavy clear method to carry out liquid-solid separation, obtained containing the leach liquor that manganese satisfies the subsequent handling requirement.
The present invention adopts the pressurized acid leaching method from the spessartine ore deposit, to leach and reclaims manganese, through pressurized acid leaching, strengthens greatly and leaches reaction conditions, destroys mineral structure, directly soaks the manganese that dissolves in the spessartine ore deposit.The spessartine ore wet process metallurgical method that the present invention adopted can extract most manganese in the mineral, and present method production efficiency is high, free from environmental pollution.
The beneficial effect of the invention is: can directly leach the manganese in the spessartine ore deposit, help improving the utilization ratio of manganese resource, enlarge the raw mineral materials kind of manganese hydrometallurgy; Through strengthening reaction conditions; The spessartine mineral failure that existing Wet-process metallurgy method can't be decomposed decomposes; Extract wherein contained manganese; Realize that soaking of spessartine ore deposit dissolved and recovery manganese wherein, adopt method of the present invention can under the condition of less expensive, effectively extract the manganese in the spessartine mineral, improve the utilization ratio of manganese resource; The calorific loss that the large quantity of moisture evaporation brings in the leaching process of having avoided when operation is carried out in closed container heating, reactant gases of avoiding simultaneously overflowing in the operation process and acid mist pollution environment and to operator's harm, improve operating condition; Technology of the present invention possesses skills advanced, easy to operate, and resource utilization is high, and the manganese leaching yield is high, and the activity duration is short, and technical process is short, and labour productivity is high, eco-friendly characteristics.
