Abstract
A reverse floatation depress ant of iron ore is prepared from starch, chloroacetic acid, methanol, NaOH, sodium carbonate and water through mixing chloroacetic acid with sodium carbonate, adding starch, stirring, adding the mixed solution of methanol, NaOH and water, and stirring. Its advantages include low dosage, simple preparing process, and high grade of ore concentrate.
Description
The present invention relates to a kind of iron ore antifloating inhibitor and preparation method thereof.
Iron ore antifloating inhibitor adopts modified starch more in the prior art, as causticization starch, CMS etc.Have following defective in production application: reagent consumption is big, the cost height; The process for preparation complexity need be heated, the high preparation of hear rate back starch is perishable, causes waste big; It is low to sort efficient, index error, cost height.
The objective of the invention is to study a kind of novel iron ore antifloating inhibitor, make its consumption in production application low, suppress the efficient height, be easy to preparation, anti-rotten, reduce medicament expense usefulness to reach, refer to that height sorts efficient.
Iron ore antifloating inhibitor of the present invention is achieved through the following technical solutions:
This inhibitor is made up of starch, monoxone, methyl alcohol, NaOH, soda ash and water, and the weight proportion of various components is: starch: monoxone: methyl alcohol: NaOH: soda ash: water=100: 15～17: 19～23: 7～9: 9～11: 0.7～1.8.Its best proportioning is a starch: monoxone: methyl alcohol: NaOH: soda ash: water=100: 16: 22: 8: 10: 1.5.
Preparation process of the present invention is: at first monoxone and soda ash stirring and evenly mixing, add then and stir 5～10 minutes in the starch; Again the mixed solution after methyl alcohol, NaOH and water-soluble the separating is added wherein, stirred 10～15 minutes; Be warming up to 65～67 ℃, be incubated 2.5 hours, products therefrom is iron ore antifloating inhibitor of the present invention after pulverizing.
Iron ore antifloating inhibitor of the present invention has following feature: suppress can prepare under efficient height, the consumption normal temperature simple, the saving energy consumption of making up a prescription; Suppress the efficient height, improve concentrate grade 0.3～0.5%,
As follows for specific embodiments of the invention: after getting monoxone 80Kg, soda ash 50gK stirring and evenly mixing; Pour in the container that 500Kg starch is housed, stirred 5～10 minutes; Again the mixed liquor after the NaOH of 40Kg (solid caustic soda) and 110Kg methyl alcohol and the 4.5Kg water stirring and dissolving is added in the starch bowl, stirred 13 minutes; Last steam is heated to 65～66 ℃, is incubated 2.5 hours, and products therefrom is iron ore antifloating inhibitor of the present invention after crushed.
The present invention with the starch contrast, can reduce consumption 45～50% with existing; Preparation need not middle temperature And secondary agitation, simplified the technology of making up a prescription; Concentrate grade improves more than 0.5%, and is difficult for becoming Matter (can reach more than 20 days summer)
