Abstract

A method of particle fluorite is recycled in flotation from tailing, includes the following steps：After tailing is milled to mineral monomer dissociation, pH regulators are made using sulfuric acid, waterglass makees dispersant, and methyl orchid makees inhibitor with soluble starch, and vegetable oil acid makees collecting agent and recycles to obtain fluorite hair concentrate to microfine fluorite first time flotation；Then fluorite hair concentrate is made into pH regulators using sodium hydroxide, larch extract makees inhibitor with Congo red, and oxidized paraffin wax soap makees collecting agent second of flotation of progress and recycles to obtain fluorite concentrate.Can preferably solve that fluorite grade is low, granularity is fine, concentrate grade requires high technical problem using the present invention, especially to disseminated grain size in tailing fluorite mineral that are thin, failing monomer dissociation recycling, concentrate grade and the rate of recovery can be taken into account.

Description

A method of microfine fluorite is recycled in flotation from tailing
One, technical field
The present invention relates to a kind of recovery method of fluorite, especially a kind of side of the recycling of the flotation from tailing microfine fluorite Method.
Two, background technology
With the development of industry, gradually deficient and price constantly increases fluorite resource, some heaps are stored in micro- in Tailings Dam Fine-grained disseminated grain low-grade fluorite becomes valuable secondary resource；But due to these low-grade fine-grained disseminated grain fluorite tailings have it is poor, Carefully, miscellaneous feature not only needs suitable technological process, while also needing to rational medicament to recycle current secondary resource System could recycle it.As can these secondary resources are fully recycled, only Mining Enterprises do not provide economic effect Benefit, while being also the meaning that fluorite industrial expansion has reality.
Three, invention content
The method of flotation that the purpose of the present invention is to provide a kind of from tailing recycling microfine fluorite, can preferably solve Fluorite grade is low, granularity is fine, concentrate grade requires high technical problem, especially thin to disseminated grain size in tailing, fail list The recycling of the fluorite mineral of body dissociation, can take into account concentrate grade and the rate of recovery.
The present invention reaches above-mentioned purpose using following technical scheme：A kind of side of the recycling of the flotation from tailing microfine fluorite Method includes the following steps：
(1) after dissociating tailing ore grinding to mineral monomer, pH regulators are made using sulfuric acid, waterglass makees dispersant, methyl Blue to make inhibitor with soluble starch, vegetable oil acid makees collecting agent and recycles to obtain fluorite hair concentrate for the first time to microfine fluorite；So Fluorite hair concentrate is made into pH regulators using sodium hydroxide afterwards, larch extract makees inhibitor with Congo red, and oxidized paraffin wax soap is made Collecting agent carries out second of flotation and recycles to obtain fluorite concentrate；
(2) it when first time flotation is recycled, after tailing ore grinding to mineral monomer is dissociated, is firstly added sulfuric acid and makees pH adjustment Agent, add water glass make dispersant and then methylate orchid and soluble starch make inhibitor, it is last again plus vegetable oil acid makees collecting Agent is scanned four selected recycling microfine fluorites by one roughing and obtains fluorite hair concentrate three times,
When (3) second of flotation are recycled, sodium hydroxide tune pH value is added to be 10.5~11 fluorite hair concentrate pulp, larch Tannin extract makees inhibitor with Congo red, and oxidized paraffin wax soap makees collecting agent and sweeps to obtain fluorite concentrate twice by the way that one roughing four times is selected,
The total dosage of medicament is：
600~1000g/t of sulfuric acid
1500~2000g/t of waterglass
200~250g/t of methyl orchid

200~300g/t of oxidized paraffin wax soap,
In use, being first configured to following mass percentage concentration %：
Unless otherwise stated, percentage of the present invention is mass percent, and the sum of each component content percentage is 100%.
The present invention's has the prominent advantages that：
1, using secondary separation technological process, separation for the first time does not directly acquire final concentrate, only obtains fluorite hair concentrate, Hair concentrate reduces separating difficulty, realizes effective recycling of microfine fluorite ore, obtain by detaching acquisition final concentrate again High fluorite concentrate grade and high-recovery.
2, using nontoxic inhibitor inexpensive, selectively good to gangue mineral, inhibiting effect is strong, tailing is preferably solved The technical issues of middle microfine fluorite difficulty recycling.
3, dosing is few, nontoxic and pollution-free.
