Product Description:

 

Description 

 Ferro Silicon is a kind of ferroalloy which consists of ferrum and silicon. Ferro Silicon uses coke, quartz 

(or silica) as raw materials and is made by electric furnace. Because silicon and oxygen are easily compound 

into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking. 

Features 

 1. Fesi 75% is often used as deoxidizer in steel- making.   

2. It can be used as a reductant in ferroalloy production and chemical industry. 

3. In iron industry it can be used as inoculant and nodulizer.

Q:Where are the major iron ore deposits in China?What is the total reserves of iron ore in China?
Ore containing S, P impurities rarely, Benxi men's Fen iron ore containing P is very low, is the smelting of high-quality pig iron raw materials
Q:What's the weight of a cubic iron ore?
Any ore containing an iron element that is economically useful is called iron ore.. There are many kinds of iron ore, mainly iron ore (Fe3O4), hematite (Fe2O3) and siderite (FeCO3).
Q:The difference between iron ore and iron ore
Iron ore: in theory, which contains iron or iron compounds ore iron ore can be called; but, in the industry or business, but does not contain iron ore to the ingredients, and must use the value of the job.
Q:Is iron ore a renewable resource?
It mainly includes biological resources (renewable), land resources, hydropower, climate resources and so on. Is the use, consumption and processing, combustion, waste and other procedures, in a certain period (predictable) repeated formation, self-renewal and recovery characteristics, a kind of natural resources and sustainable use, corresponding to non renewable resources, sustainable development is to strengthen the construction of and promote the use of clean energy.
Q:What is the purpose of pyrite ore crushing when pyrite produces sulphuric acid?
Pyrite (FeS2) is often mistaken for gold because of its pale yellow copper and bright metallic luster. It is also called "fool's gold"". The composition usually contains cobalt, nickel and selenium, and has a NaCl type crystal structure. The composition is the same as that of the orthorhombic (orthorhombic) system, called the white iron ore. Trace amounts of cobalt, nickel, copper, gold and selenium are often found in the composition. When the content is high, they can be recovered and utilized in the process of extracting sulfur.
Q:Where can I find iron ore in my world?
Iron ore is widely distributed. If iron is to be dug, it must be at a height below sea level. Only coal is available
Q:Characteristics of hematite
Steel gray to black iron, often with a light blue tarnish; aphanitic or powder were dark red to bright red. Characteristics of cherry red or reddish brown streak. Metallic luster to semi metallic luster; sometimes dull. No cleavage. Because double crystals can be split and split. Hardness 5~6. Relative density 5.0~5.3. Polarizing microscope: red, orange, yellow. One axis crystal (-), No=2.988, Ne=2.759. The crystal form of ore is usually a plate shape, mainly composed of surface (parallel, double sides) and rhombohedral. The aggregates are diverse in shape: crystalline, flaky, scaly, or blocky in shape; crystalline in a oolitic, renal, powdery, and earthy form. According to the morphological characteristics of hematite, and some of the following names: with metal luster lamellar aggregates, called hematite; with metal luster of fine flake like aggregates, called mica hematite; is called oolitic hematite or reniform oolitic or reniform; powdered hematite called iron ochre.
Q:The difference of iron ore in white iron ore
Crystals often appear in tabular form. A collection of nodular, spherical, stalactitic, crustified etc.. White to pale yellow copper ore, with light gray or light green color, fresh white tin surface approximation, streaks of gray green, metallic luster. Opaque, hardness of 6 ~ 6.5, the proportion of 4.8 to 4.9, brittle, cleavage parallel, {101} incomplete, the fracture is jagged, with weak electricity.
Q:How to distinguish chalcopyrite and pyrite with naked eyes?
The composition is usually containing cobalt, nickel and selenium, with NaCl type crystal structure. Often have a complete crystal shape, a cube, eight face body, five horns and twelve surface body and poly shape. In parallel with the crystal edge stripes cube crystal on the surface of each crystal face stripes perpendicular to each other. A dense collection of massive and granular or nodular. Yellow (Tong Huang) green and black color, streak, strong metallic luster, opaque, no cleavage, uneven fracture, the surface conditions easily weathered limonite.Pyrite is the most widely distributed sulfide mineral. It can occur in all kinds of rocks. Pyrite is the main raw material for extracting sulfur and making sulphuric acidchalcopyrite
Q:Do waste rock iron have any harm to human body?
The pyrite pyrite smelting sulfur harm on environment and governance of the 1. indigenous smelting sulfur harmful, sulfur dioxide gas generated a strong stimulation, cause damage to the eyes and respiratory system, when the concentration reaches 8 * 10-6 to 20 * 10-6, causing coughing and eye discomfort, when the concentration exceeds 5 * 10-4, will endanger life. Damage to the environment is also very serious, in the indigenous smelting sulfur area, the surrounding farmland and forest were destroyed, barren, waste gas pollution serious destruction of the natural ecological balance.
