Background technology
Producing in the artificial rutile process with the hydrochloric acid leaching ilmenite concentrate, the iron compound dissolving in the ilmenite concentrate enters hydrochloric acid and forms artificial rutile mether liquor, and this solution is to produce the superfine iron oxide good raw material.But in the time of ferric oxide that this solution of domestic usefulness is produced ultra-fine (about 1.3～1.5 μ m), Cl ion is not wherein but handled preferably.
For example, in being the application for a patent for invention prospectus of CN1052098A, publication number discloses a kind of method with continuous production of high-purity iron oxide from ferrous salt.This method be with the ferrous salt solution after the purifying treatment in the crystal seed for preparing joins one group of placed in-line mechanical stirring aeration tank, utilize control ammonia add-on, adjust the pH value 2.5～6.0, temperature maintenance is at 75～90 ℃, make in the ferrous ion oxidation and formation crystalloid ferric oxide, the contain ammonium solution and lime or magnesia of attached product react, and reclaim ammonia and return the oxidation neutralization.Though this method has obtained ferric oxide, ammonia is regenerated, and technical process is very complicated, also can produce the waste residue that contains calcium chloride, magnesium chloride simultaneously, brings severe contamination to environment.
And for example, a kind of method of extracting ultrafine iron oxide from dilute hydrochloric acid method rutile waste liquor in being the patent of invention specification sheets of ZL90105886.6, the patent No. is disclosed.This method be with in the rutile waste liquor after dealuminzation, titanium are handled, solution is put into oxidizing tower and is fed chlorine oxidation, the solution of getting after the oxidation feeds the ammoniacal liquor neutralization under strong mixing, to the pH value 5～8, make the iron ion in the solution form ferric hydroxide colloid, this ferric hydroxide colloid is after adding water slurrying, add iron filings and ferric iron solution reaction, control reaction terminating pH value is 2.5～4.0, temperature is 60～95 ℃, obtain iron oxide yellow, the gained iron oxide yellow is calcined in calcining furnace, then obtain red iron oxide.This method can obtain high-quality iron oxide yellow or iron oxide red, but the technical process complexity, and to use deleterious chlorine, understand by-product equally and contain Cl in a large number
-The waste liquid that ion is high brings severe contamination to environment.
For another example, a kind of method of making iron oxide product from solution of ferrous chloride in being the patent of invention specification sheets of ZL94108555.4, the patent No. is disclosed.This method is to use air as oxygenant, and lime is as neutralizing agent, and the crystal seed mixing with spent pickle liquor or artificial rutile mether liquor and prepared beforehand blasts air simultaneously and adds milk of lime gradually, and the iron ion formation crystallization in the solution is separated out.This method production cost is low, contains the higher solution of calcium chloride in a large number but produce, and also can bring pollution to environment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method for recovery and treatment components from mother liquid of artificial rutile, utilizes this method to remove and can directly obtain the superfine iron oxide powder, also can obtain the hydrochloric acid of regenerating, and makes artificial rutile mether liquor C1
-Ion obtains recycling.
The technical solution adopted for the present invention to solve the technical problems is: method for recovery and treatment components from mother liquid of artificial rutile of the present invention comprises the steps:
(1) artificial rutile mether liquor is filtered, elimination solid impurity wherein, heating concentrates then, and iron concentration is wherein improved, and the heating thickening temperature is 80～95 ℃, and the iron concentration in the concentrated solution is 220～240g/l;
(2) the gained concentrated solution is sprayed into the roasting kiln roasting, fire box temperature in the stoving oven is 680～700 ℃, concentrated solution concentrated solution under high temperature oxidation atmosphere is atomized into spent acid microballoon pearl, and pyrolysis takes place spent acid microballoon pearl immediately, forms hydrogen chloride gas and based on the soild oxide of ferric oxide;
(3) soild oxide decline falls in the feed bin of stoving oven bottom, obtains ultra-fine (about 1.3～1.5 μ m) ferric oxide through fragmentation again;
(4) hydrogen chloride gas rises through the absorption of absorption tower water, obtains regeneration hydrochloric acid.
The invention has the beneficial effects as follows, adopt atomizing roasting and elevated temperature heat decomposition reaction directly to obtain superfine iron oxide powder and regeneration hydrochloric acid, do not need operations such as oxidation complicated in the conventional art, neutralization, crystallization, do not use auxiliary materials such as chlorine, ammoniacal liquor, lime, magnesia, gained regeneration hydrochloric acid can return in the leading portion leaching ilmenite concentrate process and utilize, the whole process unharmful substance is got rid of, and the chlorion in the artificial rutile mether liquor has obtained the recovery and the utilization of fullest.In addition, the present invention also have simple for process, cost is low, non-environmental-pollution, economically viable characteristics.
