Product Description:

 

Description 

 Ferro Silicon is one  of ferroalloy which is made from  ferrum and silicon. Ferro Silicon uses coke, quartz 

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

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

Features 

1. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel. 

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:How much iron content in domestic iron ore has qualified?
Iron ore in North China is mainly distributed in Hebei, Xuanhua, Qian'an and Handan, Xingtai, Wuan, mining villages and other places, as well as Inner Mongolia and Shanxi. Shougang, Baotou Steel, TISCO and Handan, Xuanhua and Yangquan and other iron and steel plant raw materials base.Luan mining area to move to Anshan lean magnetite ore, containing acid gangue, S, P, fewer impurities, ore beneficiability good.
Q:Where is China's largest iron ore resource?
As of the end of 2007, the national iron ore mineral resources reserves of 613.35 tons, the basic reserves of 223.64 tons, 389.71 tons the amount of resources, China's iron ore reserves were found for the vast majority of poor and rich iron ore mineral resources reserves of 10.02 tons, the total iron ore reserves of 1.6% identified resources.
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:The rocks I see in my world make sure they have iron ore around them
Where there is magma, there are a lot of minerals nearby
Q:What are the environmental protection elements in iron ore?
The iron ore resources China much and not rich, with low grade ore, ore reserves accounted for only 1.8%, while the ore reserves accounted for 47.6%. Small and medium-sized mines, large mines less, large mines less. Ore type is complex, difficult to ore dressing and multi component (CO) ore occupies a major proportion. The hematite and multicomponent ore reserves accounted for the total reserves of 1/3, the total (with) component including V, Ti, Cu, Pb, Zn, Co, Nb, Se, Sb, W, Sn, Mo, Au, Ag, S, rare earth element 30 the main types are Ti, V, Nb, Cu, Co, S and rare earth elements, some common (with) component of economic value even more than the value of iron ore, such as Baiyunebo iron ore rich in REO and Ta, Nb; Panzhihua Sefstromite in V and Ti reserves in the world before a. With the improvement of separation and application technology, these common components will be fully recovered and utilized. Some red ore useful components, cloth size, or with harmful components embedded closely, difficult to choose, not recycling, resulting in iron ore beneficiation recovery rate is low, a large number of useful components lost to tailings. There are some magnetite ore deposits with low middle grade but easy to pick and choose. Among them, low grade ore with many marginal benefits, if appropriate economic stimulus policy, can also be fully exploited and utilized.
Q:Where is iron ore made from iron?
Iron ore mainly magnetite (theoretical iron 72.4%), hematite (theoretical iron 70%), limonite (theoretical iron 53~56%), siderite (theoretical iron content of about 48%) and so on.
Q:What tools should I use for iron ore in my world?
Iron ore must be made a stone pick, before it can be excavated and collected, the stone pick is the first line of three pebbles (through wood mining)
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:How many operations are required from iron ore to steel?
The main products are pig iron, the by-products are slag and furnace gas (see the process and principle of smelting)pig ironSteel pig iron: the mass fraction of silicon is low (wSi<1.25%), the fracture is silvery white, mainly used in steel makingCast iron: high mass fraction of silicon (wSi>1.25%~3.2%), the fracture was black, used in cast materials
Q:Where's the biggest iron mine in China?
China is a country with abundant total iron ore resources and low iron content. At present, the proven reserves of 1834 mining areas, total reserves of 463 tons of ore, ranking fifth in the world. In addition to Shanghai and Hongkong Special Administrative Region, iron ore is distributed all over the country, with the most abundant resources in Northeast and North China, followed by Southwest and Central South china.
