Abstract
The invention discloses an inhibitor for beneficiation. The inhibitor comprises, by weight, the following raw materials: 50-60 percent of water glass, 15-25 percent of sodium sulfate and 25-35 percent of modified starch, and the inhibitor is formed by diluting, dissolving and mixing the water glass, the sodium sulfate and the modified starch. Thus, inhibitor is simple in formulation, convenient to use, low in cost, easy to obtain, free of poison and harm, capable of effectively removing obstruction of flotation by carbonate minerals in fluorite mines when being used in beneficiation, capable of improving the recovery rate by 10-15 percent and improving the concentrate grade by 3-10 percent, and particularly suitable for being used in fluorite mines which are high in calcium carbonate content and difficult to select.
Description
Technical field:
The present invention relates to a kind of ore dressing with inhibitor and preparation method thereof, select the inhibitor in fluorite ore deposit and preparation method thereof in particular as the carbonate-type difficulty.
Background technology:
The global fluorite deposit of having found has number of different types at present, be mainly the filling explanation type vein deposit in the carbonate rock, stratiform in the carbonate rock, like stratiform explanation type mineral deposit and silicalite mineral deposit, China's fluorite resource is abundant, but because of its lean ore many, rich ore is few, companion's (being total to) is living, and the type ore deposit reserve is many, the single type ore deposit reserve is few, along with single fluorite ore resources reserves are constantly exploited and decline rapidly, in order to satisfy the demand of economic development, the development and use in the living type fluorite of companion's (being total to) ore deposit also obtain people's attention day by day, and this also is the potentiality place that following fluorite resource utilizes.
Carbonate-fluorite type ore, intergrowth mostly is lime stone-fluorite, sericite, calcite, quartz-fluorite, muscovite, calcite-fluorite, calcite-fluorite etc., calcite and dolomite are modal calcium minerals, they generally do not have industry to reclaim meaning, but increased the difficulty of separating them, make the technology of this type of FLOTATION SEPARATION raw mineral materials become complicated, especially the carbonate-type fluorite ore deposit that contains calcite, because the floatability of calcite and these two kinds of mineral of fluorite is close, its ore dressing is a difficult problem always.
The dressing method in this class ore deposit generally adopts the method for flotation at present, and regime of agent adopts fatty acid to make collecting agent more, and the mechanism of action of this class collecting agent is its contained anion and Ca
2+In conjunction with, thereby play the effect of collecting, and have other to contain Ca in the fluorite ore deposit
2+Gangue mineral, usually select waterglass for use, sodium metaphosphate, lignosulfonates, dextrin, tannic acid or sulfuric acid and waterglass combination are as the inhibitor of calcic gangue mineral, waterglass wherein, sulfuric acid and waterglass are combined as the inhibitor that suppresses silicate mineral, sodium metaphosphate, tannic acid is other calcium mineral inhibitor, lignosulfonates, dextrin is the inhibitor of carbonate containing mineral, but most of carbonate mineral content surpassed 3% fluorite ore deposit, the inhibition of these inhibitor does not reach the requirement of production far away, particularly carbonate content surpasses 10% fluorite ore deposit, the use of these inhibitor often can only make in the concentrate calcium carbonate content control in raw ore calcium carbonate content level, even calcium carbonate content surpasses content in the raw ore in the concentrate.
Summary of the invention:
The objective of the invention is at present ore dressing industry, the carbonate containing mineral provide a kind of and can effectively reduce calcium carbonate content in the concentrate this present situation of active demand of floating agent in the ore, improve ore dressing inhibitor and preparation method thereof of concentrate grade.
The object of the present invention is achieved like this: a kind of ore dressing is with activator and preparation method thereof, it by following raw material by weight component form: waterglass 50～60%, sodium sulphate 15～25%, converted starch 25～35%.
Waterglass of the present invention is 10% Na
2SiO

Converted starch of the present invention is converted starch and the composite modified starch that starch makes by physics, chemistry, enzyme process.
Being starch by the obtained converted starch of physical method handles, bakes the converted starch that processing, gamma-rays processing, hyperfrequency radiation treatment, mechanical lapping processing, humid heat treatment make by pre-gelatinization (α-change).
Being starch by the obtained converted starch of chemical method handles the converted starch that makes by acidolysis, oxidation, crosslinked, esterification, etherificate, grafting.
By the obtained converted starch of the enzyme solution converted starch that to be starch handle by enzyme, as α, β, cyclooctaamylose, maltodextrin, amylose.
Composite modified starch is for uniting the converted starch that makes by in physics, chemistry and the enzymatic isolation method two or more.
Preparation method of the present invention is:
1), dilution: with concentration be 40%, modulus is 2.8～3.0 waterglass, thin up to 10%;
2), dissolving: 10% waterglass and sodium sulphate according to the above ratio, in container, put into waterglass, slowly add sodium sulphate, the limit edged stirs, and makes it to dissolve fully;
3), mix: take by weighing the converted starch of aforementioned proportion, slowly in the colloid mixture that adding has stirred, the limit edged stirs, and interpolation finishes, and continues to be stirred to mix.
The present invention compared with prior art has the following advantages:
1. the present invention has adopted waterglass, sodium sulphate, converted starch to form activator, thereby prescription is simple, easy to use, and institute's with medicament is ore dressing medicament commonly used, and is cheap and easy to get and nontoxic;
2. the present invention selects the fluorite ore deposit to make inhibitor for the difficulty that contains carbonate mineral, can improve the rate of recovery 10～18%, and concentrate grade improves 3～10%.
3. alternative of the present invention is adsorbed in the carbonate mineral surface, thereby shield its electric charge and prevent collecting agent combination with it, reach the purpose of inhibition, have good selective and inhibition, can effectively suppress the carbonate mineral in the fluorite, as calcite, lime stone, aragonite etc., to the unrestraint of noncarbonate mineral, and clay mineral (as kaolin, fire clay) there is flocculation, therefore also has the desliming effect except suppressing the carbonate mine beyond the region of objective existence, can help to improve the rate of recovery.
4. inhibitor operating position of the present invention, by experiment repeatedly, flotation fluorite effect calciferous such as following two tables:
Be the experimental pharmacy effect, now adopt CaF
2Content is 35.1%, CaCO
3Content is 5.2% fluorite ore deposit 1 and CaF
2Content is 30.3%, CaCO
3Content is that following two groups of experiments are done in 10.2% fluorite ore deposit 2:
Table 1 fluorite ore deposit 1 experiment effect
Table 2 fluorite ore deposit 2 experiment effects
By last two tables as can be seen: the inhibitor that uses this patent to invent can effectively suppress the carbonate in the mineral, can obtain the higher rate of recovery and high-quality product.
