Description
Technical field
The present invention relates to the method that a kind of purification of ore is brightened, and in particular to a kind of that barite ore is purified and increased
White method, belongs to technical field of fine.
Background technology
Nonmetal mineral product of the barite using barium sulfate as main component, it is pure barite whitening color, glossy, due to impurity
And the influence of tramp material also normal gray, light red, light yellow etc., being that distributed in nature is most wide contains baryta mineral.Barite
Learn property stable, water insoluble and hydrochloric acid, nonmagnetic and toxicity.
Barite is a kind of critically important nonmetallic ore raw material, with extensive industrial use.In drilling well, pigment, change
All there is important utilization in work raw material, cement industry, road construction, but as high-quality, single type barite deposit are increasingly withered
Exhaust, existing most of barite deposit grade is low, with other metallic ores, the close association of nonmetallic ore, it is necessary to after purification
It can use.
Existing barite method of purification include physical purification and chemical purification, wherein physical purification include picking, gravity treatment,
Magnetic separation, at present in industrial production business with being gravity treatment and magnetic separation extensively, but the purification limited precision of gravity treatment, it is impossible to meet high standard
Accurate requirement, and magnetic separation is simply possible to use in removing magnetic mineral, function is more single；Chemical purification industrially mainly includes flotation
And pickling, wherein flotation is mainly used to distinguish specific two kinds of mineral matters, it is impossible to remove the unknown impuritie of multiple types, acid wash master
To be used for dissolving part acid soluble impurities and organic matter, its impurity-eliminating effect is still not ideal enough.
The content of the invention
For the deficiency in the presence of prior art, the invention provides the method that a kind of purification of barite is brightened, it is used to
Solve existing barite purification method of whitening can not comprehensively and effectively remove plurality of impurities present in barite raw ore and
The problem of effectively being brightened.
To achieve the above object, present invention employs following technical scheme：
A kind of method that barite purification is brightened, comprises the following steps：
(1) ore is pre-processed：Barite tcrude ore break process to diameter is less than 30cm first, washing tcrude ore is removed
Sludge, then carries out second-time breakage and handles tcrude ore to 3cm, be finally ground processing, tcrude ore is handled to 100
Within mesh；
(2) pickling is purified：According to the gross mass of pending raw material, the water and 2% part by weight of 100% part by weight are added
Sulfuric acid, then progressively add hydrochloric acid, fully reaction to the pH value of the aqueous solution is 1, then adds the water of 100% part by weight, then
The hydrofluoric acid of 2% part by weight is added, stirring reaction 8~12 hours finally removes waste liquid, added more than 200% part by weight
Water fully clean raw material, to pH be more than 2；
(3) processing is brightened：Raw material is diluted to 50% concentration, the sodium hydrosulfite of 2% part by weight is added, stirred 2~4 hours
It is fully reacted, then clean raw material and be more than 6 to pH, last drying material obtains finished product.
Compared to prior art, the present invention has the advantages that：
1st, the present invention first adds sulfuric acid and hydrochloric acid removes the acid soluble materials such as carbonate, metal in barite raw material, so
The impurity insoluble in acid such as hydrofluoric acid dissolution silicate is added afterwards, can be by the foreign metal in barite tcrude ore, metal
The impurity such as oxide, organic matter, carbonate, silicate are all removed, and greatly improve the purity of barite, through the present invention's
Method handled after barite in the content of barium sulfate can reach more than 97%, carried compared with prior art with larger
Rise；
2nd, the present invention is additionally added the sodium dithionite tool in sodium hydrosulfite progress bleaching, sodium hydrosulfite after acid pickling step
There is strong reducing property and Bleachability, the nonferrous metal oxides in barite raw material and organic matter etc. can be subjected to reproducibility drift
In vain, the whiteness of barite product is improved, the barite whiteness of method processing of the invention can reach more than 94, it is remote super existing big
Most products；
3rd, step of the invention all uses solution reaction, can disposably operate continuously, it is not necessary to carry out raw material transfer,
It is adapted to large-scale industrial production, is conducive to improving operating efficiency.
