Abstract
The invention belongs to a method for extracting various metals from tailings. The method comprises the following steps of: high-intensity magnetic concentration and ball milling: ball milling an ilmenite material, carrying out spiral separation and fine concentration by using a spiral concentrator to obtain a separated and concentrated material and removing waste residues; low-intensity magnetic concentration: carrying out low-intensity magnetic concentration by using a magnetic concentrator for separation and concentration to obtain low-quality iron powder and an ilmenite fine concentrated material; and extracting: extracting the ilmenite fine concentration material, wherein the ratio of the ilmenite fine concentration material to an extracting agent to water is 1,000:(1-3):1,000. The method can effectively extract titanium or other metals from waste tailings and has the advantages of simplicity, convenience, easy application, simple process and low cost and can greatly improve the utilization effect of the waste tailings.
Description
Technical field
The invention belongs to a kind of method of from mine tailing, extracting multiple metal.
Background technology
At present, the steel of Laigang, Shandong are processed used whole ores, iron powder all from geographic Yishui County, Yi Mengshan Mountain, find that from the eighties this area stores large-area titanium ore, but the deficiency that contains a large amount of micas and ferrotianium mineral intergrowth material is arranged in this ilmenite, be difficult to extract, separate.Domestic scientific research personnel does not all achieve success through great amount of investment and research experiment at present, cause a large amount of wastings of resources, especially this area can only extract iron in nearly hundred ore deposits since 03 year from ilmenite, and the rare metals such as titanium that wherein contain are all abandoned as waste material, and titanium metal does not obtain extraction and application.Titanium and alloy thereof have the little excellent properties such as corrosion-resistant, high temperature resistant of density.The country that can carry out the titanium suitability for industrialized production at present in the world has only a few countries such as the U.S., Japan, Russia, China, the year Gross World Product of titanium only has several ten thousand tons, but because the great strategic value of titanium and the status in national economy, titanium will become " the 3rd metal " that emerges after iron, aluminium, 21 century will be the century of titanium.The production method of current titanium adopts metallothermics, adopt 24000-40000 ℃ high temperature mostly, high pressure, equipment utilization metallic reducing agents (R) such as high vacuum are finished with the prepared in reaction of metal oxide or muriate (MX), the titanium metallurgical method of having realized suitability for industrialized production is magnesium reduction process (Kroll method) and sodium thermoreduction method (Hunter method), because the Hunter method is than Kroll method production cost height, so have only the Kroll method in industry-wide method at present, the Kroll method was from exploitation in 1948, originally just because of its cost height, reduction efficiency is low and on the pan, over half a century has gone over, this technology does not change, remain batch production, fail to realize the serialization of producing.World's titanium industry is through the development of decades, although Kroll method and Hunter method have been carried out a series of improvement, but still be unable to do without complex operations operations such as high temperature, high pressure and high vacuum, and they all are periodical operation, little improvement can not reduce the price of titanium significantly.Therefore should develop new, continuous process could fundamentally solve this problem of high production cost cheaply.
Summary of the invention
The purpose of this invention is to provide a kind of method of from mine tailing, extracting many sections metal, can extract titanium or other metal effectively again from the depleted mine tailing with this method, this method has simple and easy to do, and technology is simple, cost is low, can increase substantially the advantage of utilizing effect of depleted mine tailing.
This method comprises the steps:
(1) high strength magnetic separation is carried out the high strength magnetic separation with the mine tailing material with magnetic separator, gets ferrotianium mineral aggregate and slag charge;
(2) ball milling carries out ball milling with the ferrotianium mineral aggregate, carries out spiral separation with spiral concentrator and selects materials selected must the separation, removes waste residue;
(3) low strength magnetic separation is selected materials separation and is carried out the low strength magnetic separation with magnetic separator, must hang down product iron powder and ferrotianium choice stock;
(4) extraction, ferrotianium choice stock: extraction agent: water=1000: 1 to 3: 1000, the ferrotianium choice stock is extracted, and what described extraction agent was the massfraction of solute in the sulfuric acid of 90%-95%, hydrochloric acid, nitric acid is a kind of, 120 ℃～230 ℃ of extraction agent temperature, pressure 3～30 bar absolute pressures, stir, 50～90 minutes time, after filtration, must extract material, the extraction material is removed the multiple metal powder that extraction agent gets content 80%～85% through washing.Described ferrotianium choice stock: extraction agent: water=1000: 1: 1000.Described ferrotianium choice stock: extraction agent: water=1000: 2: 1000.Described ferrotianium choice stock: extraction agent: water=1000: 3: 1000.
Advantage of the present invention is as follows:
1, of the present invention have an advantage efficient, energy-conservation, that reduce discharging, can extract titanium or other metal effectively again from the depleted mine tailing with this method, overcome the deficiency that the titanium rare metal that can only extract iron from ilmenite at present and wherein contain is not used.Can increase substantially society and economic benefit, the limited Mineral resources of China are fully used, can increase substantially the effect of utilizing of depleted mine tailing, increase substantially production efficiency.
2, of the present invention method is simple, and technology is simple, and extraction separation speed is fast, and cost is low, and the purity height has saved complicated technologies such as high temperature, high pressure, saves energy consumption at least 80%.
Embodiment
Choose the depleted mine tailing of the intact iron ore of the geographic extraction in Yi Mengshan Mountain, the mine tailing material is carried out the high strength magnetic separation with high strength magnetic separator (magnetic table intensity is 4000-10000 Gauss), get ferrotianium mineral aggregate and slag charge (discarding).Again the ferrotianium mineral aggregate is carried out ball milling, carry out selectedly with spiral concentrator, must separate and select materials, remove dregs.Separation selected materials carry out the low strength magnetic separation, must hang down product iron powder and ferrotianium choice stock with low strength magnetic separator (magnetic table intensity is 1800-2100 Gauss).Remove low product iron powder, use as ironmaking.
Select the extraction of ferrotianium choice stock, ferrotianium choice stock: extraction agent: water=1000: 1 to 3: 1000, the ferrotianium choice stock is extracted, and what described extraction agent was the massfraction of solute in the sulfuric acid of 90%-95%, hydrochloric acid, nitric acid is a kind of, 120 ℃～230 ℃ of extraction agent temperature, pressure 3～30 bar absolute pressures, stir, 50～90 minutes time, after filtration, must extract material, the extraction material is removed the multiple metal powder that extraction agent gets content 80%～85% through washing.Titanium accounts for 95% in the multiple metal powder, and iron accounts for 4%, and all the other are metals such as aluminium, manganese, silicon.Described ferrotianium choice stock: extraction agent: water=1000: 1: 1000.Described ferrotianium choice stock: extraction agent: water=1000: 2: 1000.Described ferrotianium choice stock: extraction agent: water=1000: 3: 1000.Described magnetic separation is wet separation.
In a word, the present invention can extract titanium or other metal effectively again from discarded mine tailing, and the method has simple and easy to do, and technology is simple, and cost is low, can increase substantially the advantage of utilizing effect of discarded mine tailing.
