Abstract
The invention discloses a method for utilizing barium slag to prepare precipitated barium sulfate and hydrochloric acid. The method is technically characterized in that the barium slag is used for reacting with the hydrochloric acid so as to obtain chlorides mainly comprising barium salt; filtrate is extracted to react with a small amount of barium sulfate to recover chlorine ions so as to obtainbarium chloride subject to complete reaction; and finally the barium chloride and sulfuric acid react with each other to obtain the precipitated barium sulfate. The method not only can create a high economic value but also can eliminate waste ore garbage and simultaneously prepare the precipitated barium sulfate of various grades.
Description
Technical field:
The present invention relates to the technical field that the chemical sludge three wastes are handled, especially a kind of with the process white of barium slag preparation and the method for hydrochloric acid.
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 process white of barium slag preparation and method of hydrochloric acid used, adopting said method not only can be created very high economic worth, and, can also remove abandoned mine rubbish, can also process each other process white 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:
Baric slag and the dilute hydrochloric acid mass ratio 1 by pure substance: 0.15-0.55 places acidleach jar (1) lining, afterreaction 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: 0.358-0.758 then and generates various barium salts.
Acidifying and recovery back suction filtration (4) get clear liquid and sulfuric acid synthesizes process white in combination apparatus (5) lining according to mass ratio 1: 0.27-0.67, the rotating speed 60-300 of agitator rev/min, use whizzer (6) washing at last, separate, dry (7), pulverizing (8) etc. becomes the process white product.Filtrate and washes main component are hydrochloric acid, become low salt acid product through decompression inspissation, also can recycle.
