Embodiment 1

[0032] Such as figure 1 , figure 2 As shown, a system proposed in the present embodiment is extracted in a variety of price elements in boronite, including a pulverizer 10, a vertical calcination furnace 20, a water shower pad 30, a pelletizer 40, a filtration device, and a return According to the device, wherein the pulverizer 10 has a pulverizing machine feed port 11 and a pulverizing machine outlet portion 12, a pulverizing machine outlet port 12 and a side wall in which the vertical calcination furnace 20 is connected, and the pulverizing machine outlet 12 is baked. The connection of the side wall of the furnace 20 has a gates that control the open and closed.

[0033] The vertical calcination furnace 20 also includes a flue gas pipe 23, a filter tower 24, a first filter layer 25, a reintening tube 26, a vertical calcining furnace discharge port 28, and the ammonia pipe conduit 29, and the lower portion of the vertical calcination furnace 20 has The baked position, the upper e...

Embodiment 2

[0044] This embodiment proposes a method for extracted a variety of price element extraction in boronite ore, using a system extracted in a variety of price elements in the boron iron ore as presented in Example 1.

[0045] According to the chemical composition, mineral composition and thermodynamic analysis of boronite ore, the process flow of ammonium ammonium sulfate roast boronite:

[0046] The abrasive boron iron ore is mixed with ammonium sulfate, iron, aluminum, magnesium, boron in boron ore reactively generate soluble salts, silicon generates silica to be soluble in water; roasting flue gas dust removal Got ammonium sulfate solid, return to mix, recycle;

[0047] Excessive ammonia is used for sinking iron, Shen aluminum, Shen magnesium;

[0048] After the calcination is dissolved, the silica is dissolved in water, and the filtration is separated from sulfuric acid dissolved in water;

[0049] The filtrate uses ammonia regulation pH to sink iron, Shen aluminum, Shen magnesi...

Embodiment 3

[0053] In conjunction with Examples 1 and Example 2, specifically, the specific use process of the device is as follows:

[0054] In boronite, iron content is about 30%, including B 2 O 3 10%, MGO 30%, SIO 2 20%, Al 2 O 3 About 5%, boronite and ammonium ammonium sulfate ore is inserted to the pulverizing machine immersion port 11, the boron iron ore is pulverized to the boronite powder between the particle diameter of 80 μm, and the pulverized boron iron ore is discharged through the pulverizer. The port 12 entered the vertical calcination furnace 20, which dropped to the calcination flap 22, and mixed with ammonium sulfate and boronite powder in the above process. The vertical bolt furnace 20 is calcined to boron iron powder and ammonium sulfate powder to produce ammonia gas and ammonium sulfate powder, and the resulting flue gas enters the filter tower 24 through the flue gas pipe 23. Ammonium sulfate powder in the flue gas was filtered through the first filter layer 25, and the...

Abstract

The invention relates to the field of energy and chemical industry, in particular to a system for extracting various valuable elements in paigeite. The system comprises a crusher, a vertical roasting furnace, a water spraying filter bin, a precipitator, a filter device and a material returning device. The system can directly process and crush iron ore. By means of the multiple steps of roasting, water spraying separation, pH value adjustment for iron precipitation, aluminum precipitation, magnesium precipitation, filtrate evaporation, crystallization and separation and the like, mineral substances in iron ore are directly separated, silicides, boron, iron, aluminum and magnesium in paigeite can be extracted, the equipment can complete separation of most mineral substances in paigeite, meanwhile, cyclic utilization of ammonia gas and ammonium sulfate is achieved, pollutant emission is extremely small, and environmental protection and high efficiency are achieved. The invention further provides a method for extracting various valuable elements in paigeite.

Description

Technical field [0001] The present invention relates to the field of energy chemical, in particular a system for extracting a variety of price elements in boronite ore. Background technique [0002] Boron Rati is the most important boron resource in my country. Its full iron content is about 30%, including B 2 O 3 10%, MGO30%, SIO 2 20%, Al 2 O 3 About 5%. At present, the treatment process of boronmite includes a wet method and fire method only limited to boron and iron in which it is recycled, and other useful substances are called waste residue, but not only a large amount of land, but also causes serious pollution to the environment. . Inventive content [0003] In order to solve the above problems, a system for extracting a variety of price elements in boronite is extracted, and silicides, boron, iron, aluminum, and magnesium in boronite can be extracted. The present invention also proposes a method for using a variety of price element extraction in boronite ore. [0004] In...
