Abstract
The invention relates to a flotation agent which can be used for high-purity refined iron-mineral powder. Three additives, such as an inhibitor (starch), a foaming agent (oil II), lime and the like are adopted on the basis of adopting laurylamine; and the invention has the effects on purifying fine iron minerals to 72.5 percent and reducing an acid insoluble matter to 0.10 percent.
Description
Technical field
The present invention relates to a kind of fine iron breeze floating agent, mainly is that to be used for effectively reducing fine iron breeze contained various as SiO
2Deng impurity content, improve fine iron breeze purity and the new floating agent taked.
Background technology
Iron ore is produced the main original material of various steel as steel mill, comprise that powder metallurgy aspect etc. all uses in a large number, but the iron ore iron-holder of various places differs, and the major part low ore deposit that is grade, for in use, effectively improve lumber recovery, save energy consumption, used Iron Ore Powder will improve purity to greatest extent, also will avoid causing in order to improve purity the part mineral powder loss simultaneously.At present, two kinds of ore dressing modes of conventional employing, a kind of is magnetic separation, promptly adopts ore is pulverized, directly carry out magnetic separation with magnetic separator, this method is suitable for vignite such as magnetic iron ore, but its effect is general, part contains the iron ore loss, and in the Iron Ore Powder of selecting, still contains a large amount of impurity; A kind of is inverse flotation method, and this kind method is effective, adopts special-purpose floating agent, and the impurity in the iron ore is effectively proposed, and has both reduced impurity content, improves purity, has reduced the loss of Iron Ore Powder again, is present reasonable method.But the present floating agent that adopts and not really desirable, the one, dosing is big, and the 2nd, can not be fast wherein impurity be effectively broken away from.
Summary of the invention
The purpose of this invention is to provide a kind of flotation agent for high-purity refined iron-mineral powder that is exclusively used in, solved the big problem of present production high-purity refined iron-mineral powder purification difficulty, this medicament use amount is few, but reach effective.
For reaching above purpose, the technical solution adopted in the present invention is: on the basis of original lauryl amine, hydrochloric acid, adopted inhibitor, foaming agent and three kinds of additives of lime, wherein, the Main Ingredients and Appearance of inhibitor is a starch, and purpose is the loss of control iron, the bigger raising rate of recovery; Foaming agent mainly is a 2# oil, and purpose is to improve air admission hole to make the bubble effect, can effectively impurity be put forward; And utilize lime is that the modulation of ore pulp Acidity of Aikalinity is met the state that this medicament is caught impurity.Above-mentioned several material comprehensive function, can be efficiently with in the fine iron breeze as SiO
2Deviate from Deng impurity content, the highlyest the ore deposit can be purified to 72.5%, hydrochloric acid insoluble substance content is reduced to 0.10%, as be used for powder metallurgy industry production iron ore concentrate sponge iron, reach 98.5% through once reducing iron content, also can be used for making steel sponge iron etc., steel mill uses can improve production effect greatly, cut down the consumption of energy, improve lumber recovery.
Beneficial effect of the present invention is: compare in present existing floating agent, fine iron breeze is purified and is sampled height, and the loss of iron is few, the production efficiency height.
The specific embodiment
A kind of flotation agent for high-purity refined iron-mineral powder of preferred embodiment of the present invention on the basis of lauryl amine, has added inhibitor, foaming agent and lime.The main component of described inhibitor is a starch, is used to control the loss of iron, the bigger raising rate of recovery; The main component of described foaming agent is a 2# oil, is used to improve air admission hole and makes the bubble effect, effectively impurity is put forward.
This floating agent adopts following production stage:
Equipment: agitator (stainless steel is made, and prevents corrosion).
Size: the each stirring is the 2-2.5 ton.
Preparation method:
1, raw material: lauryl amine, hydrochloric acid
2, amine elder generation heating for dissolving is become liquid, be added in the agitator, temperature generally is added to and begins to add hydrochloric acid about 70-80 degree centigrade;
3, earlier with after the hydrochloric acid dilution, slowly add with pipe;
4, prepare in proportion, stir and added water in 3 hours again and stirred 18 hours, water will be used soft water;
5, must not be less than 24 hours from being heated to end.
6, the medicament that processes is in use allocated inhibitor, foaming agent and three kinds of additives of lime into.
Claims (3)
1. a flotation agent for high-purity refined iron-mineral powder is characterized in that: on the basis of lauryl amine, added inhibitor, foaming agent and lime.
2. floating agent according to claim 1 is characterized in that: the main component of described inhibitor is a starch, is used to control the loss of iron, the bigger raising rate of recovery.
3. floating agent according to claim 1 and 2 is characterized in that: the main component of described foaming agent is a 2# oil, is used to improve air admission hole and makes the bubble effect, effectively impurity is put forward.
