The production method of the wollastonite mine tailing after acidifying: by abrasive dust in the wollastonite mine tailing batching input grinding machine after acidifying, the powder after abrasive dust is the wollastonite mine tailing after acidifying.
Wollastonite is a kind of inorganic needle-like mineral, its feature is nontoxic, resistance to chemical attack, heat endurance and dimensionally stable good, there are glass and pearly luster, low water absorption and oil factor, mechanical property and electrical property are good and have certain strengthening action, the present invention selects the wollastonite mine tailing after pulverizing, grain fineness≤0.5 millimeter of wollastonite mine tailing.
Concave-convex clay rod has unique layer chain structure feature, and crystal is needle-like, fibrous or fiber collection shape.Concave-convex clay rod has unique dispersion, high temperature resistant, the anti-good colloidal nature such as saline and alkaline and higher adsorption capacity, and has certain plasticity and cohesive force, and the present invention selects grain fineness≤5 millimeter of Concave-convex clay rod.
Magnesia has the general character of basic anhydride, belongs to Binder Materials, can improve the colloidal property of wollastonite mine tailing.
It is 98% the concentrated sulfuric acid that sulfuric acid is selected concentration.
Quick dissolved sodium silicate is white granular material, can be dissolved in fast water, has that cohesive force is strong, intensity is higher, acid resistance, good heat resistance, the feature of alkali resistance and poor water resistance.
Polyethenol series white solid, that external form is divided is cotton-shaped, graininess, Powdered three kinds; Nonpoisonous and tasteless, graininess can be dissolved in 80--90 DEG C of water, pulverously after other powders pre-dispersed, can dissolve at normal temperatures.There is good viscosity, polymerism, caking property and water-retaining property.
Hydroxypropyl methylcellulose has thickening capabilities, salt discharge, pH stability, water-retaining property, dimensional stability, good film forming and the feature such as resistance to enzyme, dispersiveness and caking property widely.
Sodium carbonate has the general character and the heat endurance of salt, soluble in water, and its aqueous solution is alkalescence, in the present invention for adjusting the wollastonite mine tailing pH value after acidifying.
The present invention is achieved by following technical proposals:
1, the batching of the wollastonite mine tailing after acidifying is made up of following component by weight percentage: wollastonite mine tailing semi-finished product 90～98%, quick dissolved sodium silicate 0.1～5%, polyvinyl alcohol 0.1～5%, hydroxypropyl methylcellulose 0.01～3% and sodium carbonate 0～3% after acidifying.
2, the production method of the wollastonite mine tailing after acidifying: by abrasive dust in the wollastonite mine tailing batching input grinding machine after acidifying, grain fineness≤0.074 millimeter, the powder after abrasive dust is the wollastonite mine tailing finished product after acidifying.
3, the half-finished production method of wollastonite mine tailing after acidifying: stir in the mixer (1) input of the batching of wollastonite Tailings mixture having been turned round, then dilute sulfuric acid is slowly added and carries out acidification in wollastonite Tailings mixture; (2) by the wollastonite Tailings mixture after acidification, push as wollastonite mine tailing tablet thickness≤3 millimeter of wollastonite mine tailing tablet by twin rollers; (3) wollastonite mine tailing tablet is transported to roasting in swinging drying oven, roasting time is 1～3 hour, sintering temperature is controlled at 250～350 DEG C, wollastonite mine tailing tablet water content≤5% after roasting, wollastonite mine tailing tablet after roasting is the wollastonite mine tailing semi-finished product after acidifying, and PCm is weight percentage.
4, the batching of wollastonite mine tailing tablet is made up of following component by weight percentage: wollastonite Tailings mixture 75～95% and dilute sulfuric acid 5～25%.
5, the batching of wollastonite Tailings mixture is made up of following component by weight percentage: wollastonite mine tailing 68～92%, Concave-convex clay rod 5～30% and magnesia 0.1～3%.
6, the batching of dilute sulfuric acid is made up of following component by weight percentage: the concentrated sulfuric acid 1～25% that concentration is 98% and water 75～99%, the concentrated sulfuric acid percentage that concentration is 98% is weight percentage.
The production method of the wollastonite mine tailing after acidifying takes first acidifying to carry out compounding ingredient again, can avoid sulfuric acid and quick dissolved sodium silicate, polyvinyl alcohol, hydroxypropyl methylcellulose and sodium carbonate generation chemical reaction, give full play to raw-material characteristic separately in batching, and obtain complementation, guarantee the wollastonite mine tailing inherent quality after acidifying.
