Baotou's mineral resources are characterized by many kinds, large reserves, high grade, concentrated distribution and easy exploitation, especially metal minerals, among which rare earth minerals are not only the dominant minerals in Baotou, but also the treasures of national mineral resources. 74 minerals have been discovered, including 14 mineral types. The main metal minerals are: iron, rare earth, niobium, titanium, manganese, gold, copper and other 30 minerals and 6 minerals. Non-metallic minerals include: limestone, dolomite, pulse time, fluorite, vermiculite, asbestos, mica, graphite, gypsum, marble, granite, calcite, perlite, apatite, potash feldspar, gemstone, amethyst, hibiscus, copper orchid, bentonite, kaolin, whitening clay and brick clay. Energy resources include: coal, oil shale and so on.

Known as the grassland steel capital

Anshan

There are 35 kinds of proven mineral resources in Anshan. The most abundant reserves are iron, magnesite, talc, jade, marble, limestone, granite and boron. The proven reserves of iron ore are 654.38+0.8 billion tons, ranking first in China. Mainly distributed around Anshan city and Gongchangling in Liaoyang city. Except a few small and medium-sized iron mines distributed in Haicheng and Xiuyan, the large iron mines such as Dong 'anshan, Dagushan, Qidashan, Qian Qian Mountain and Gongchangling are all mined by the state. Magnesite is mainly distributed in the eastern mountainous areas of Haicheng and Xiuyan. The proven reserves are 2.3 billion tons, which is also the first in China, accounting for 1/4 of the world's reserves, with excellent texture and grade. Large-scale mines include Liaoning Coal Company, Huaziyu Magnesium Mine, Yaolingzi Magnesium Mine and township enterprises such as Yingluo, Pailou and Bali. Xiuyan is mainly mined in Pianling and Sanjiazi. Talc minerals are mainly distributed in Haicheng and Xiuyan. The proven reserves are 60 million tons. Haicheng talc mine, located in Fanjiabaozi, Ma Feng Town, Haicheng City, is mined by the state, and the rest are mined by township enterprises. The talc in Haicheng and Xiuyan enjoys a high reputation in the international market because of its white purity and low impurities such as iron and calcium. Jade minerals are mostly distributed in Xiuyan. Xiuyan is known as the "hometown of jade". A small amount is distributed in Gushan Town, Haicheng. Xiuyan jade stone has a proven reserve of 2.06 million tons and an annual mining capacity of about 2,500 tons, making it the largest jade producing area in China. In addition to the jade carving factories and shops in the county, Xiuyan jade stone is also supplied to more than 70 jade carving factories in 22 provinces across the country for processing. Xiuyan jade is exquisite and pure in texture and colorful, including green, yellow, black, red and white. Xiuyan jade carving products are one of the main products exported by Dalian Port. Marble, mainly produced in Xiuyan and Haicheng, has huge reserves. Marbles in the two places are colorful, including red, yellow, black, white and green, which are the treasures of advanced building materials. Limestone is mainly distributed in Xiuyan and the eastern mountainous area of Haicheng, and also distributed in Tangjiafang and Dagushan Township of qianshan district, with considerable reserves. Limestone in the above areas has good texture and stable grade, with calcium content of 53%, which is a good raw material for cement production. Granite, mainly produced in Xiuyan Manchu Autonomous County, has a reserve of over 20 billion tons. Among them, black granite, after being cut into plates, is simple, elegant and unique, and is known as the "king of stones". Other mineral and metal deposits include lead-zinc mine, copper mine, nickel-cobalt mine, gold mine and pyrite mine; Non-metallic minerals include silica minerals, phosphate rocks, asbestos, fluorite, vermiculite, muscovite, barite, boron minerals, clay minerals, graphite, coal and petroleum.

Panzhihua

Pangang-praised by foreign metallurgical experts as "a miracle in the history of world metallurgy".

Pangang-also known as "ivory micro-carved steel city".

Pangang-built on a steep hillside, is a large enterprise with an annual output of 3 million tons of steel.

Among the world's iron and steel enterprises, Pangang covers an area of only 2.5 square kilometers. The iron ore used in Panzhihua Iron and Steel Company is the most refractory polymetallic ore in the world. It has been the dream of many metallurgical experts in the world for a hundred years to smelt this vanadium-titanium magnetite with ordinary large blast furnaces. After a lot of research and experiments, China people have overcome this technical difficulty and smelted qualified molten steel from Panzhihua iron mine rich in rare and precious metals such as vanadium, Qin, gallium and scandium.

This technology won the first prize of scientific and technological invention of China government. The unique smelting process is even more amazing. In order to improve the variety structure and support and promote the economic development of the whole western region. From 65438 to 0986, Panzhihua Iron and Steel Company raised funds extensively at home and abroad, invested nearly 10 billion yuan, and began to build a large-scale second-phase project. After ten years of struggle, this project, which is equivalent to rebuilding a large steel enterprise, was fully completed and put into use in 1997.

The completion of this project not only makes the equipment level of Panzhihua Iron and Steel Company a big step forward, but also fundamentally changes the product structure of Panzhihua Iron and Steel Company, and no longer only produces primary steel products. In particular, the rolling system can not only produce special steel products such as railway rails, but also produce a variety of plate products.

The railway rails of Pangang are very famous in the world, not only for domestic use, but also exported abroad in large quantities. The service life of rails produced by Panzhihua Iron and Steel Co., Ltd. with the latest technological achievements has been doubled, and a series of large steel products mainly made of rails has been formed, which is very popular at home and abroad. Pangang's plate products have also formed a series.

There are more than 200 varieties and specifications. The sheet products of Panzhihua Iron and Steel Company are excellent raw materials for manufacturing industries such as home appliances and automobiles in China. In addition to steel products, Panzhihua Iron and Steel Co., Ltd. is also a major producer of vanadium products in the world, accounting for more than 80% in the domestic market and 15 ~ 18% in the international vanadium market. It is an important export base of China.

Panzhihua Iron and Steel's titanium products have also formed a certain scale, not only supplying the domestic market, but also exporting abroad.

There are many more ... some of them.
