Description
Technical field:
The present invention relates to the technical field that the chemical method mineral products extract, especially a kind of method of the general thin process white with the barium ore preparation.
Technical background:
Extracting various materials since ancient times in ore all is with the method for smelting, and no matter is metal or nonmetal, also has inorganic salt etc.The method equipment of this smelting is huge, and complex process and investment are very big.The development of science and technology chemical method extracted and arose at the historic moment modern age, came out first, and became the main method that the chemical mine material extracts.It is simple that its characteristic craft simply reaches equipment, and investment seldom and profit advantages of higher very, is that current chemical mine extracts irreplaceable approach.The present invention utilizes this chemical method to extract the process white product of various fineness, comprises the extracting method of sodium nano-barium sulfate.
Summary of the invention:
The invention provides a kind of method of the general thin process white with barium ore preparation, is that Processes and apparatus is simple than its prior art characteristics, and investment seldom and profit advantages of higher very, is that current chemical mine extracts irreplaceable approach.The present invention utilizes this chemical method to extract the process white product of various fineness, comprises the extracting method of sodium nano-barium sulfate.
In order to reach above-mentioned purpose, technical scheme of the present invention is:
Its technical process of barium ore after acidifying and the recovery is:
Baric slag and the dilute hydrochloric acid mass ratio 1 by pure substance: 0.13-0.53 places acidleach jar (1) lining, the reaction back generated the muriate based on barium in 4-8 hour, suction filtration (2) obtains waste residue filter cake and muriate, uses barium sulfate to reclaim muriate in withdrawer (3) lining according to mass ratio 1: 0.359-0.759 then and generates various barium salts.
Acidifying and reclaim back suction filtration (4) clear liquid with tensio-active agent handle the back with sulfuric acid in combination apparatus (5) lining according to pure mass ratio 1: 0.26-0.66 synthesizes process white, the revolution of agitator is 60-300 rev/min, use whizzer (6) washing at last, separate, dry (7), pulverize (8), selection by winnowing etc. become each other general thin process white product of level.Filtrate and washes main component are hydrochloric acid, become low salt acid product through decompression inspissation, also can recycle.
The superfine precipitated barium sulfate series product comprise: the micro mist process white accounts for 52%; The super-fine powder process white accounts for 36%; Superfine precipitated barium sulfate accounts for 15%.
