Abstract
The invention discloses a method for preparing micro precipitated barium sulphate series products by using barium slag. The main technical proposal comprises: reacting the barium slag with hydrochloric acid to obtain chloride taking barium salt as main component; filtering clear solution, and reacting the product with small quantity of barium sulphate to reclaim chlorine radicals so as to obtain barium chloride after complete reaction; and finally, reacting barium chloride with sulphuric acid to obtain micro precipitated barium sulfate of various grades. The method not only can create high economic value, but also can clear waste ore rubbish and process the micro precipitated barium sulphate of various grades at the same time.
Description
Technical field:
The present invention relates to the technical field that the chemical sludge three wastes are handled, especially a kind of method of using the superfine precipitated barium sulfate product of barium slag preparation.
Technical background:
The scoriaceous source of barium is varied, and when exploitation barium ore deposit produced various baric products, the waste residue of discharging just contained very high-grade barium element, even grade is more taller than primary ore.It is quite low to produce its cost of process white with this waste residue, and can also remove barium ore deposit rubbish.Comparing with the same industry and to occupy very big price advantage and industrial advantages, also have policy and resources advantage etc., is a kind of extraordinary process for processing approach.
Summary of the invention:
The invention provides a kind of method of using the superfine precipitated barium sulfate series product of barium slag preparation, adopting said method not only can be created very high economic worth, and, can also remove abandoned mine rubbish, can also process each other precipitated barium carbonate of level simultaneously.
In order to achieve the above object, technical scheme of the present invention is:
Its technical process of barium slag after acidifying and the recovery is:
Barium slag and the dilute hydrochloric acid mass ratio 1 by pure substance: 0.15-0.55 places acidleach jar (1) lining to carry out chemical reaction slowly, generate muriate after 4-8 hour based on barium, suction filtration (2) obtains waste residue filter cake and muriate, uses barium sulfate to reclaim muriate in withdrawer (3) lining according to pure mass ratio 1: 0.358-0.758 then and generates various barium salts.
Acidifying and reclaim back suction filtration (4) clear liquid with the 1-3% tensio-active agent handle the back with sulfuric acid in combination apparatus (5) lining according to pure mass ratio 1: 0.27-0.67 synthesizes process white, the revolution of agitator is 120-300 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 48%; The super-fine powder process white accounts for 36%; Superfine precipitated barium sulfate accounts for 16%.
