1. China's steel output last year was 100 million tons, accounting for 44 of the world's total steel output, importing 100 million tons of iron ore and producing 100 million tons of iron ore. 2. China's iron ore reserves are also second to none, but the current situation of China's iron ore is unevenly distributed, the quality of iron ore is poor, and there are a lot of waste slag ore in one ore. In Australia, India, the purity of the ore is very high, and the quality of the ore is also good.
3 Mainly used in urban construction, but there is also industrial steel demand, mainly: high-end machinery, elevators, precision equipment, munitions, shipbuilding, aircraft, railway locomotives, automobiles, aerospace instruments, production machinery, special steel and other large steel users. There are still a lot of them to be exported.
4 China is the world's largest importer of iron ore, China's annual purchase of iron ore accounts for about 39 of the world's total iron ore production, the export of finished steel accounts for about 52 of the world's total steel production and exports, so the iron ore is of great importance to our country and Australia's imported iron ore is not only of good quality, but also much cheaper than domestic production.

Now I can't see any problems, and as I said upstairs, the reconstruction of Wenchuan needs steel - but this is all ** analysis. The fact that the price of iron ore has not dropped does not mean that there will be no problem in a few months or even years, and the demand in Wenchuan cannot digest the remaining steel in our country at all. I believe that the landlord only has the demand for iron ore in China.
I'll give you a piece of information. China's top 10 industries with excess capacity now include steel and cement. When the production capacity of China's steel and cement industry is fully released, our steel and cement reserves will likely exceed global demand.
In this way, you should be able to judge for yourself what the iron ore demand will be in the medium to long term. In my humble opinion, in the medium to long term, the demand for iron ore will definitely decline. Happy Chinese New Year.

ChinaIron oreThe reserves are more than 45 billion tons, and the poor ore is more sellable, and the rich ore is less, and the rich iron ore only accounts for 33% of the national average grade of iron ore, which is 11 lower than the average grade of iron ore in the worldPercentage points, the demand for raw materials cannot meet the needs of domestic production. Based on this situation, in the past 10 years, with the rapid development of the domestic iron and steel industry, China's iron ore imports have increased year by year, and the trend of global allocation of slag bucket trapped iron ore resources has been formed.
In 2010, China's iron ore importers reached 40, with an import volume of 100 million tons, accounting for about 67% of the total iron ore consumption, an increase of nearly 32 percentage points over ten years ago. In 2011, the number of iron ore importers has expanded to 63, and the import volume reached 100 million tons, a year-on-year increase.
11%, accounting for a further increase in total iron ore consumption.
The safety of China's iron ore imports is still guaranteed. Now China is also opening up more import markets. Iron ore companies have also begun to expand their purchases of mines abroad, and some even have direct holdings. For example, Guinea in Africa.
Simandou Iron Mine, the world's largest iron ore mine, has cooperation intentions with China. In short, the current iron ore is mainly the reason for capital speculation, and China's iron ore is still the best.

In 2020, the global iron ore reserves were 180 billion tons, of which China's iron ore reserves were 20 billion tons, accounting for the world's total reserves, second only to Australia, Brazil and Russia. However, the average grade of iron ore in China is only, and the reputation of lead is far lower than the average grade of iron ore in the world. China's iron ore imports account for more than 65% of the world's major iron ore imports, and its dependence on foreign countries is nearly 90%.
Taste requirements. The grade of iron ore refers to the mass fraction of the iron element in the iron ore, which is commonly known as the iron content. For example, an iron ore grade of 62 refers to a mass fraction of 62% iron.
For hematite (the main component is Fe2O3), the theoretical maximum grade is 70%.
For magnetite (the main component is Fe3O4), the theoretical maximum grade is:
For the dusty siderite (the main component is Feco3), the theoretical maximum grade is.
For limonite (the main component is Fe2O3 H2O), the theoretical maximum grade is:

Summary. Hello dear, glad for your question oh <>
The cost of iron ore mining in China: the cost of iron ore mining in China is more than US$40 tonnes, and BHP Billiton and Rio Tinto are US$20 per ton.
The cost of iron ore mining in China.
Hello dear, glad for your question oh <>
China's iron ore mining costs: China's iron ore mining costs are more than 40 US dollars, BHP Billiton and Lizheng Zaotuo are 20 US dollars of closed travel yuan.
Iron ore is an important raw material for iron and steel production enterprises, and natural ore (iron ore) is gradually selected through crushing, grinding, magnetic early separation, flotation, gravity separation and other procedures. Iron ore is an aggregate of minerals containing iron elements or iron compounds that can be economically utilized. The world's iron ore resources are concentrated in Australia, Brazil, Russia, Ukraine, Kazakhstan, India, the United States, Canada, South Africa and other countries.
As the world's largest iron ore demander, China's own iron ore reserves are not small, but unfortunately the grade is relatively low, from the perspective of industrial economy, it is better to import from Australia, Brazil and other countries rich in iron ore.
How much does it cost to do work in the iron ore cave?
How much does it cost to transport, 2500 meters, a section of five meters by five meters, in total?
Dear, iron ore mining is generally 30 100 yuan tons, the specific amount should be determined according to the thickness of the vein, the difficulty of mining, the local labor, the material cluster (blasting items, drill bits, drill rods, electrical materials, etc.), electricity costs and contracting methods; Lead infiltration excavation (footage) ** is generally 1000 2000 yuan meters, the specific amount should be determined according to the size of the section specifications, combined with local labor wages, materials (blasting materials, drill bits, drill rods, electrical materials, etc.), electricity costs ** infiltration and contracting methods can be determined.
I'm asking about the mining standards set by the state**.
For example, in coal mines, they have a lottery, standard**.
Dear, the latest** iron ore is 644 yuan a ton.
What I want to ask is the source of the difference in iron ore, the national standard, the inside of the hole, the transportation of 2,500 meters to three kilometers, the workers drilling and blasting, the drill pipe bit, the loading and transportation, the electricity fee, etc., do the project more reed state and less money? How much is a ton of mining keeping?
Dear, the cost of deep hole blasting contracting in the mine is 30 yuan per ton per bush. The cost of blasting and blasting in medium and deep holes is yuan m infiltration. Iron ore blasting** table is priced at 6,000 tons of iron ore produced in RI.

Generally speaking, the evaluation criteria for iron ore taste include the following:
1.TFE standard: TFE refers to the proportion of the mass of iron contained in iron ore to the mass of the whole ore.
In general, the higher the TFE content, the higher the taste of the iron ore. Generally speaking, the minimum requirement for TFE is more than 55%, and only iron ore that meets this standard has the value of mining, beneficiation and processing.
2.Theoretical taste standard: Theoretical taste refers to the minimum taste standard that meets the requirements of optimal mining conditions and economic benefits in terms of identifying the chemical composition and physicochemical properties of ores.
This standard is generally more than 60%, that is, the mass of iron ore containing iron is greater than or equal to 60%.
3.Economic Taste Standard: This is a taste standard formulated on the basis of market demand and technical conditions, which will be adjusted according to the guess change of market demand, generally between 58% and 60%.
In short, the iron ore taste reaches a certain standard before it is worth mining, and it is also necessary to comprehensively consider factors such as market demand, technical level, transportation capacity, etc., in order to choose the best mining method and ensure economic benefits and environmental protection standards.

According to the data published by the World Steel Association, the number of iron ore imports from countries and regions around the world in 2020 will reach 100 million tons. Among them, the amount of iron ore imported by China is as high as 100 million tons, accounting for about 70% of the world's total. China imports most iron ore mainly because China's steel industry has the world's largest production capacity, and China does not produce iron ore.
Although China has all iron ore contracts in the ** exchange, the pricing power is not in China. However, with the stupid size of this hall, more entry and less entry will definitely affect the market. Hope mine can help you!

Hello, dear. China's machinery casting industry and steel industry need iron ore. Iron ore can be smelted into pig iron for foundry machinery products, and then melted into molten iron through the smelting furnace, and cast lead into molding sand or starvation molds, becoming cast iron parts and blanks needed in mechanical production and life.
After the billet is smelted into molten steel, we will make the molten steel into the different steel we need. To meet the needs of industrial production and life. China is currently the world's largest importer of iron ore, accounting for 1 3 of the world's total imports.
The world's iron ore resources are concentrated in Australia, Brazil, Russia, Ukraine, Kazakhstan, India, the United States, Canada, South Africa and other countries. Iron ore is an important raw material for steel. More than 80% of the iron ore needed in the Chinese market depends on imports, with Australia and Brazil being the main importers.
Iron ore imports from these two countries account for more than 60% and more than 20% of China's total imports, respectively.

Iron ore demand = crude steel production. According to the formula of this calculation problem, the demand for iron ore = crude steel output, and the import volume + raw ore conversion amount = the import volume of the month + the output of the raw ore of the month 3. Spring loss.
The main methods for extracting iron from iron ore are blast furnace method, direct reduction method, melt reduction method and plasma method. Among them, blast furnace ironmaking is to send iron ore and coke, carbon monoxide, hydrogen and other fuels and fluxes to the blast furnace for smelting in batches by the furnace top charging device according to the specified batching ratio, and remove impurities to obtain metallic iron (pig iron). >>>More

Iron ore has a high titanium content, and the titanium can be removed, depending on the composition of the iron ore. Sedimentary ores can be considered, as conventional ilmenite contains iron that can be separated. If it is a sea placer ore, it needs to be carefully considered, because the ore may be a mixture of compounds containing both titanium and iron, and it may be cemented or moltened, which is not possible to be treated by conventional ore processing. >>>More
In general, it can be burned and calcined in the air.
