Description
The present invention relates to the process in a kind of flotation fluorite ore deposit, it is to the improvement about flotation fluorite ore deposit method of No. 87105202 granted patents.
Method according to No. 87105202 patent applications, the adjustment agent of flotation fluorite is that acid adds alkali and adds synergist, effect is than the obvious improvement of prior art, but because of synergist (carboxymethyl cellulose or calgon or prodan) price expensive, solubility is low, the amount of allocating into is few, and effect is still very good inadequately, is of limited application.Take a broad view of domestic and international fluorite present situation, the improvement of adjusting agent in the traditional handicraft is had acid system and alkaline system, the former adds waterglass for acid, and is stronger to the inhibition of siliceous minerals such as quartz, but poor stability, the flotation froth breaking seldom adopts in the production; The latter for waterglass add slaine (as US3893915, US3207304, SU1128984, SU671855 SU1002014), strengthens the inhibition to calcite, but turbidity sediment and losing efficacy easily.From prior art, can find out, the someone did not expect adjusting adding acid in the agent at alkaline system, or in acid system, add salt and improve, main cause is " acidic water glass " easily agglutination and make and adjust agent and lost efficacy, those skilled in the art attentively work hard in alkaline system.Exhausted expect in alkaline system, adding acid less or in the acid system with salt.
The purpose of this invention is to provide a kind of medicament source easily, the adjustment agent composition of make up a prescription convenience, solubility height, stable transparent, said composition is used in the fluorite process of the present invention can suppress associated minerals such as barite, calcite, quartz, mica effectively, fluorite is fully swum, thereby improve the selectivity and the rate of recovery of fluorite.
Purpose of the present invention realizes by the following method: with waterglass add acid and one or more soluble-salts of forming with this acid (as multiple salt, then the ratio of its multiple salt is 0.5: 0.1~1.0), its combination is than being: waterglass: acid: salt=1~2: 1~5: 0.5~1(weight ratio, down together), combination liquid pH≤3, be the aqueous solution of stable transparent, its concentration is 1~20%(percentage by weight).
Purpose of the present invention can also realize by the following method:
1. add oxalic acid (H with waterglass
2C
2O
4), salt uses the solubility oxalates (as Na
2C
2O
4), it makes up than being: waterglass: oxalic acid: solubility oxalates=2: 3: 1.Use oxalic acid and oxalates to separate better effects if when flotation contains more fluorite ore deposit, pyroxene ore deposit, the fluorite rate of recovery is higher.
2. add acetic acid (CH with waterglass
3COOH) add solubility acetate (as CH
3COONa, CH
3COOK etc.) adjust the agent composition, it makes up than being: waterglass: acetic acid: solubility acetate=2: 5: 1.The composition that uses this type of acid and salt thereof to form more is adapted to fluorite to be separated with quartz.
3. add nitric acid (HNO with waterglass
3) and solubility nitrate (as NaNO
3, KNO
3Deng), it makes up than being: waterglass: nitric acid: solubility nitrate=1: 1: 0.5.This based composition is more effective to the fluorite flotation of fine-grained disseminated grain.
4. add hydrochloric acid (HCl) with waterglass and soluble-salt hydrochlorate (as NaCl, KCl etc.) adjusts the agent composition, it makes up than being: waterglass: hydrochloric acid: soluble-salt hydrochlorate=1: 1: 0.5, it more is applicable to separates fluorite and barite.
5. add sulfuric acid (H with waterglass
2SO
4) and soluble sulphate (as Na
2SO
4, FeSO
4, ZnSO
4, (NH
4)
2SO
4, Al
2(SO
4)
3) being mixed into composition, it makes up than being: waterglass: hydrochloric acid: soluble sulphate=1: 1: 0.5, this based composition is more effective to separating fluorite and calcite.
6. add sulfuric acid with waterglass and add multiple soluble sulphate (as Na
2SO
4Add (NH
4)
2SO
4) make composition, it makes up than being: waterglass: sulfuric acid: multiple soluble sulphate=1: 1: 0.5, the ratio of wherein multiple salt is: 0.5: 0.1~1.0.
Above-mentioned hydrochloric acid, nitric acid, sulfuric acid etc. can substitute mutually, also can substitute mutually with the corresponding salt of this acid.
Concrete grammar of the present invention is: take sample ore, with grinde ore to fluorite monomer dissociation rate greater than 95%, the rare one-tenth concentration of water is 25~30%(solid) ore pulp, available any composition of the present invention adjusts agent, with oleic acid (or fatty acid soaps) as the collecting foaming agent of holding concurrently, under near neutral (pH=6.5~7.0) medium and normal temperature (20~30 ℃) condition, carry out flotation, roughly select foam and promptly get fluorite concentrate selected 5~7 times, the consumption of composition is according to ore character and grade and decide, generally roughly select 500~1500 gram/tons, selected 500~800 gram/tons, flotation flowsheet adopts " set composite ".So obtain concentrate grade and can reach 98~99%CaF
