Description
[technical field]
The present invention relates to mineral purification technique field, the especially a kind of method of whitening and talcum of impure talcum mud.
[background technique]
With the rapid development of social economy, talcum is widely used to papermaking, ceramics, plastics, paint, cosmetics, electricity
A industrial department of cable, pesticide etc. more than 30 proposes increasingly higher demands to the purity and whiteness of talcum (talcum mud) both at home and abroad.
Although the talcum in China finds out that resource reserve is larger, but talcum (talcum mud) resource of high-quality high-grade is fewer and fewer, this kind of
Talcum accounts for Chinese talc total output less than 20%.Liaoning, Shandong, the big place of production in Guangxi three will all enter dry spells at present.Mainly
Reason: first is that part Medium and smaller mines pass through the exploitation of many years, resource is exhausted；Second is that with development in science and technology, especially newly
The application field of the rise of material industry, China top grade talcum resource is constantly widened.
High-order talcum enumerated with the index parameter of low-grade talcum in table 1 come compared with facilitating.
1 talcum of table (talcum mud) index parameter
Low-grade talcum reserves are very big, therefore have the purification of low-grade talcum with huge economic value.
General mineral method of whitening is physics except brightening after iron or chemical bleaching method brightens, and physics mainly passes through except iron
High-gradient magnetic separation machine equipment is carried out except iron, and chemical bleaching, which mainly passes through medicament, carries out iron ion complexing except iron.At present this two
Kind method: one, physics is bleached except iron can only remove Armco magnetic iron mineral, and be mingled in most talcum (talcum mud) at present
The very high yellow mud of iron-content, for the iron dust in this yellow mud in nonmagnetic iron, magnetic plant can not carry out de_ironing refinement, while general
Pyrite containing part in talcum (talcum mud), this part iron can not equally be screened by magnetic plant, simultaneously for
The concentration of crude ore pulp requires, and it is lower that this allows for specific yield；Two, chemical bleaching method brightens, mainly by will be in mineral
Iron ion complexing after be discharged again with solution, chemical bleaching for pulp density require it is not high, can be mass-produced, but chemistry
Bleaching is equally faced with impure yellow mud in existing talcum (talcum mud), and the iron ion in yellow mud is present in lattice, if not
Yellow mud is discharged in advance, then mineral can not be bleached.
[summary of the invention]
The present invention provides the method for whitening and talcum of a kind of impure talcum mud, to by the talcum of impure yellow mud
(talcum mud) whiteness is promoted.
A kind of method of whitening of impure talcum mud of the invention, comprising steps of S1, at least by calgon, hydrogen-oxygen
Change sodium, guar gum are added in the ore pulp of impure talcum mud and stir, and obtain being stirred ore pulp；S2, it is stirred above-mentioned
Ore pulp staticly settles, and obtains sediment；S3, the sediment is washed into 2 to 3 times heel row solid carbon dioxides with clear water get talcum.
Further, also thiourea dioxide, sodium hypochlorite, disodium ethylene diamine tetraacetate are added containing miscellaneous in the step S1
In the ore pulp of matter talcum mud.
Preferably, step is specifically included in step S1: calgon, sodium hydroxide, guar gum being added impure
It is stirred in the ore pulp of talcum mud；It is added in aqueous solution thiourea dioxide, sodium hydroxide to obtain stock solution；By sodium hypochlorite
Stirring in ore pulp is added to stock solution and adds disodium ethylene diamine tetraacetate, obtains being stirred ore pulp.
Preferably, step is specifically included in step S1: specifically including step in step S1: by calgon, hydroxide
Sodium, guar gum are added in the ore pulp of impure talcum mud and stir；Impure talcum is added in thiourea dioxide and sodium hydroxide
It is stirred in the ore pulp of mud, adds sodium hypochlorite and disodium ethylene diamine tetraacetate.
Specifically, the mass parts that chemical reagent is added are as follows: using calgon 0.1wt%-5wt%, sodium hydroxide
0.1wt%-5wt%, disodium ethylene diamine tetraacetate 0.1wt%-5wt%, thiourea dioxide 0.1wt%-5wt%, sodium hypochlorite
0.1wt%-5wt%.
Specifically, the purity that chemical reagent is added is as follows: the content of the calgon is containing for 99%, sodium hydroxide
Measure 99%, the content 99% of disodium ethylene diamine tetraacetate, the content of thiourea dioxide 99%, the content of sodium hypochlorite 10%.
Specifically, treated, talcum flexural strength is 3MPa.
Specifically, treated, talcum calcining whiteness is 89-91, and the flow velocity of calcination of talc is in 22s-27s.
A kind of talcum of the invention, is prepared using the above method.
The method of whitening of impure talcum mud of the invention, breaches original chemical bleaching for the cunning of impure yellow mud
The technical bottleneck that stone (talcum mud) can not brighten is purified low-grade, rich reserves talcums (talcum mud) for height using medicament
The talcum (talcum mud) of grade, improves the added value of mineral products, has huge market value.
