Summary Molecular sieve is a kind of cubic crystal aluminosilicate compounds. Molecular sieve has the advantages of uniform porous structure, the diameter of the aperture size uniform, these holes to the adsorption of molecules smaller than the diameter of the cavity to the internal, and the polar molecules and unsaturated molecules has a preferential adsorption capacity, and are better able to different degrees, different saturation degree, molecular size and the boiling point of different molecules are separated, that is "screening" molecular, the so-called molecular sieve. Molecular sieve has the advantages of high adsorption capacity, high thermal stability, and so on, so that the molecular sieve is widely used.

Anode block The anode block is used in the 18 groove of the electrolytic cell. In the life cycle of anode carbon block, with anode were gradually consumed, anode mechanism driven carbon anode piece of the fall to ensure the electrolyzer stable configurations. When used for a certain period of time, the carbon block has become very thin (about L3 ~ 18cm), in order to prevent the molten electrolyte for the anode steel claw must replace the new anode carbon block group. These residual carbon blocks are called as residues. High calorific value, dry without water, 1 tons equivalent to 1.5 tons of metallurgical coke. Maximal residual anode carbon block is generally in the range of 15% to 25%. Residual very for a long time and electrolyte contact containing higher electrolyte components, such as aluminum, sodium, potassium, calcium, magnesium, lithium, fluorine composition, appearance is often accompanied by electrolyte formed by crust. Residue after cleaning can be used in the production process of anode materials. From the electrolytic tank to replace the residual polar group, to remove residual surface electrolyte shell, and then use the residual anode pressure disengaging machine or manual remnant pole and the guide rod is separated. With a hammer or press off and make the steel claw separating ring on iron claw. Residual anode on the residual electrolyte should be carefully cleaned, carbon product conductivity and oxidation activity of these electrolytes because, due to the gas permeation and gasification, the volume density of the residual anode decreased. After crushing and screening, the residues are divided into different sizes, which are used as a kind of aggregate to be added when the anode carbon block or anode paste is produced. Residues can also be used as fuel for smelting. Physical and chemical index Test item Detection index Test item Detection index C More than 98% Ash Less than or equal to 5% Total S Less than or equal to 1.5% Volatile parts Less than or equal to 2.3% Water Less than or equal to 1% Quantity of heat 8000 calories Anode block application Generally speaking, the tank after stripping and cleaning the anode mud, can be melted and cast anode. Some lower pole can also be used for other purposes, for example, copper sunset very as cold material added to the converter, can also be used as a raw material for manufacture of copper sulfate; nickel residual anode can be used for manufacturing of nickel ions in the electrolyte.
Brief introduction of iron powder Iron powder according to particle size, habit is divided into coarse powder, medium powder, fine powder, fine powder and ultra-fine powder five grades. Particle size of 150 to 500 mu m range of particles composed of coarse powder, particle size of 44 to 150 m for the medium powder, 10 to 44 m for fine powder, 0.5 ~ 10 m for the very fine powder, less than 0.5 m for the ultra-fine powder. General will be able to through a 325 goal quasi sieve particle size of less than 44 m powder known as Subsieve powder, if more high precision screen specific provisions can only be used air classification equipment, but for a number of easy oxidation of the iron it can only be used JZDF nitrogen protection classifier to do. Reduced iron powder, gray or black powder, also known as double suction agent, can absorb moisture and oxygen in the air, commonly used in food preservation. Reduced iron powder generally consisted of Fe3O4 under high temperature conditions in the flow of hydrogen or carbon monoxide gas reduction and generation, the main ingredient for the loose structure of elemental iron. Atomized iron powder with high compressibility, high green strength, single pressure can obtain density in pressure slab 6.80g/cm3 above, especially to the pressing and sintering with high strength parts. The scope of atomized iron powder: density in the sintering deposit of more than 6.80g/cm3 is parts, powder metallurgy forging parts. Iron powder characteristics: I plant iron, iron, HW, iron ore, atomized iron, spraying iron main characteristics of products is round rate is high, than major, the surface is smooth, particle high compressibility, good hardness, with impact force resistance, compression is good, in the spray thrown sand operations using life is long, the blasting effect is excellent, and dust, with environmental protection operations and reduce the damage to human body has the advantages of is blasting operations of high-end electronic products preferred.

Summary Spinel is a rare mineral in nature, and it must be made by artificial synthesis. According to a certain proportion of raw materials, mixing pressing ball molding (to join the right amount of pulp). The characteristics of electric furnace melting temperature, in the smelting process, to maintain the redox state, avoid Fe2O3 FeO oxidation, to prevent the emergence of elemental Fe, after natural cooling of the hercynite sand. The uniform large crystal (95%) with no grain boundary was revealed under the microscope, which was similar to that of the glassy state. After processing into the iron aluminum spinel brick, mainly used in large-scale cement rotary kiln, instead of the current cement kiln used chrome brick, no Cr6+ pollution. Extended lining service life (magnesia chrome brick 10-12 months and hercynite brick 17-18 months), greatly reducing the consumption of refractory material and manpower, reduces the production cost, the full realization of the cement kiln chrome free production, solve the chromium pollution. Fe Al spinel represents a new generation of high performance chrome free refractories for cement rotary kiln. The two main methods for the synthesis of spinel are sintering and electric melting. Most spinel material is made from high purity synthetic alumina and chemical grade magnesium oxide, namely in shaft kiln sintering and fused in arc furnace. Al Mg spinel is a kind of aluminum magnesium oxide, its main component is alumina and Magnesium Oxide. Al Mg spinel has two kinds of natural formation and artificial synthesis. Natural magnesia spinel rarely found industrial applications of magnesium aluminum spinel are all artificial synthesis, the two main methods of synthetic magnesia alumina spinel is sintering and electric melting method. etc. Spinel application Sintered magnesia alumina spinel is used for cement rotary kiln, which not only avoids chromium pollution, but also has good resistance to spalling. Sintered magnesia alumina spinel is used for making ladle pouring material, which can greatly improve the anti erosion ability of steel sheet lining. The preparation of high quality synthetic spinel provides a new raw material for the production of amorphous and amorphous high purity refractory materials. Electric melting magnesium aluminum spinel is manufacturing plate, nozzle brick, open hearth brick material. The high temperature mechanical properties of aluminum and magnesium spinel products are good, which are the basic raw materials of the filter belt, refractory casting material and high. Fused magnesia alumina spinel used in iron and steel smelting and glass industry furnace.
Barium sulfate The mineral is barite barium sulfate. White amorphous powder. Difficult to dissolve in water, acid, alkali or organic solvent. The use of barium sulfate as the main use of barium sulfate in the gastrointestinal tract can absorb X rays and the development of the role, so mainly used as gastrointestinal contrast agent. Used for making barium salts, etc.. By barium sulfate solution with the addition of after removal of calcium and magnesium of Glauber's salt mixed solution, at 80 deg.c reactions were carried out precipitate. After filtration, washing and pickling, adjusting the pH value 5 ~ 6, filtering, drying and crushing. Also available barium yellow brine and mirabilite solution was prepared.
