Where is the iron ore and is there a gold mine in the iron mine?

Misclassified, right? The scope is too big, isn't it? Where there is a lot of iron ore, there is iron ore. Let's say, Mars.

There is iron ore in Qian'an, Tangshan, Hebei Province, which is very rich in resources. Location: Beijing East.

It's simple, just look at the map of China.

Natural ore (Iron oreIron is gradually selected through crushing, grinding, magnetic separation, flotation, gravity separation and other procedures. In view of the characteristics of iron ore and the higher requirements of the iron and steel industry for iron ore concentrate, it has posed new challenges to China's filial piety mining workers. Therefore, there are deeper development requirements for China's metallurgical mine beneficiation technology, followed by the further improvement of beneficiation equipment.

The beneficiation process should be as efficient and simple as possible, such as the development of energy-saving equipment, and the best results should be achieved with the most suitable process as much as possible. In the concentrator, the equipment investment, production cost, electric energy consumption and steel consumption of crushing and grinding operations often account for the largest proportion, so the calculation and selection of crushing and grinding equipment and the quality of operation and management determine the economic benefits of the concentrator to a large extent.

Distribution of iron ore.

The world's iron ore resources are concentrated in Australia, Brazil, Russia, Ukraine and Kazakhstan.

India, 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.

The iron ore that can be directly put into the steelmaking furnace for steelmaking was formerly called "open-hearth bonanza", and the iron ore that can be directly used for ironmaking was formerly called "blast furnace bonanza", both with the word "rich". These bonanzas are preferably magnetite.

and hematite, both of which contain more than 70% iron.

Summary. Yes, there may be gold in iron mines. Gold ore is a rare metallic mineral that can be found in iron ore.

The discovery of gold deposits can be achieved through geological exploration, which can help us discover the presence of gold deposits. The steps of geological exploration include: first, conducting a geological survey to understand the geological structure; secondly, geological sampling is carried out to determine the type of mineral; Finally, geological surveys are carried out to determine the distribution of minerals.

Geological exploration can also help us understand the properties of minerals, as well as the reserves and quality of minerals. In addition, geological exploration can also help us understand the depth of minerals and the structure of minerals, as well as the composition of minerals. Through geological exploration, we can discover the existence of gold mines, so as to realize the mining of gold mines.

In addition, geological exploration can also help us understand the depth of minerals and the structure of minerals, as well as the composition of minerals. Through the exploration of Dipeihe, we can discover the existence of gold deposits, so as to realize the mining of gold mines.

Can you add, I don't quite understand it.

Yes, there may be gold in iron mines. Gold ore is a rare metallic mineral that can be found in iron ore. Gold deposits are formed due to the deep temperature and pressure of the earth's crust, as well as the action of hydrothermal fluids at depth, which dissolve the metal elements and then penetrate along the cracks in the rocks and are finally deposited in iron ore.

The gold content can vary from a few percentage points to tens of percentages, depending on the environment and depth in which the gold mine is formed. Gold mining is a complex process that requires multiple steps, including exploration, surveying, mining, concentrate, concentration, smelting, etc. Gold can be mined using both underground and surface mining methods, depending on the distribution of the gold mine.

Gold mining can be used to obtain not only metals but also other minerals such as copper, aluminum, tungsten, molybdenum, etc., which can also be used in the manufacture of various industrial products. In addition, the mining of gold mines can also bring economic benefits, improve the local sales environment, and promote the local economic development.

Iron and steel has always been the most important structural material, occupies a very important position in the national economy, is an important pillar industry of social development, and is the most important and most widely used metal material in modern industry. Therefore, people often regard the output, variety, and quality of steel and steel as an important indicator to measure the level of development of a country's industry, agriculture, national defense, and science and technology.

Iron ore is the main raw material for steel.

This is iron ore.

Mine scenery Deep part of the mine The cave is full of iron ore, and the top and bottom are all iron This is the point! Don't underestimate that these ores also contain copper, sulfur, and trace amounts**. Sunlight outside the cave.

The ore is mined from a deep well and contains waste rock, sulphur, and other impurities that require further selection to remove the initial impurities. The selected iron concentrate powder must also be sintered or pellet treated by ingredients before it can be used in the furnace.

Iron ore open pit mining:

Open-pit mining is a mining method that uses mining equipment to strip rocks and extract useful minerals stage by stage in the open pit or depression of the hillside in the open pit or depression open pit under the open conditions. Open-pit mining has many advantages compared with underground mining, such as fast construction speed, high labor productivity, low cost, good working conditions, work safety, high ore rate, small dilution loss and so on. Especially with the development of large-scale and efficient open-pit mining and transportation equipment, open-pit mining will be more widely used.

At present, most of China's ferrous metallurgical mines use open-pit mining.

The whole process of building an open-pit mine generally includes: the construction of surface facilities in the mining area; dredging and anti-drainage of mineral deposits; A series of preparations for the capital construction of the open pit stope and the commissioning of production.

The open-pit stope infrastructure project is mainly to excavate the inlet ditch, outlet ditch and section ditch, lay transportation lines, build a dump, strip rock, and build water supply, drainage, power supply facilities, etc.

The access ditch is to establish an inclined transport road from the ground to the working level and between the working levels. The open trench is the horizontal trench excavated at each level to open up the mining line, that is, the initial working line in the development phase.

Trenching, stripping and mining are the three most important parts of the open pit production process. The speed of descent of the open-pit mine and the length of preparation time for the new level are mainly determined by the speed of trenching. In order to ensure the continuous normal production of open-pit mines, a certain advanced relationship must be maintained between trenching, stripping and mining in space and time.

Follow the principle of "simultaneous mining and stripping, stripping first" to organize production.

In the production of open pit mines, whether the ore is stripped or re-mined, the process is generally perforated, blasted, loaded and transported. At present, the equipment used in China's ferrous metallurgical mines is mainly cone drilling and down-the-hole drilling, and percussion drilling has been eliminated. Most of the loading equipment uses 3 m 3 electric shovels, and electric shovels above 6 m 3 are also used.

Most of the transportation equipment uses trucks of more than 20 tons and 80 150 tons of electric locomotives, and 100 tons of electric wheel vehicles are also popularized and used in some large mines.

In terms of provinces, Liaoning Province is rich in iron ore resources, Hebei, Sichuan, Shanxi, Inner Mongolia, the above provinces are rich in iron ore resources, and Xinjiang also has relatively rich iron ore resources because of its vast area.

Nanfen Iron Mine is known as the largest iron ore mine in China.
