The scale of the deposit is mainly large and medium-sized, and the ore body is large. There are five places with reserves exceeding 100 million tons, and the average grade of ore is 36.55%. Most of them belong to easy-to-beneficiate magnetite, and the concentrate grade of 53%~64% can be obtained through mineral processing.
Gaocun, Taocun and Heshangqiao in the suburb of Maanshan, Baixiangshan in dangtu county and Luohe in Lujiang County are potential reserve mines. Pyrite is concentrated in Xiangshan and Mashan areas on the outskirts of Maanshan, with a total reserve of about 262 million tons. Associated phosphorus resources have large reserves and high grade. According to the phosphorus content in the stope and tailings dam of Nanshan Iron Mine, the reserves reach14.27 million tons.

The magnetic material industry was once a great pride of our city's industry, leading the national industry level in technology, quality and scale. But in the 1990s, the development was slow. In the new century, with the promotion of a series of policies such as the development of key industrial enterprises and the adjustment of product structure by the Municipal Party Committee and the Municipal Government, the technology and personnel of the magnetic materials industry in the city have been reshuffled, and nine leading demonstration enterprises of magnetic materials, including Tianyuan Science and Technology Company, Gaoke Magnetic Materials Company, Xinyang Magnetic Materials Company and Tongli Magnetic Materials Company, have been initially formed.
Anhui Tianyuan Technology Co., Ltd. is a joint-stock company jointly funded by sinosteel Maanshan Mining Research Institute and Anhui Hengxin Investment Development Company. On the basis of fully relying on the rich production technology of magnetic materials in Maanshan Mining Institute and magnetic separation equipment, an industrial chain with hard magnetic materials, soft magnetic materials, magnetic devices and magnetic separation equipment as the main line has been formed, and it has been listed as a leading demonstration enterprise in the construction of magnetic material production base in Anhui Province. In 2004, the magnetic material industrial chain of Tianyuan Science and Technology Company, with only more than 200 employees, realized sales income of 6,543.8+0,564.8 million yuan and profit and tax of 654.38+0.96.13 yuan. With 654.38+03 independent intellectual property patents, it has become "Anhui High-tech Enterprise" and "Anhui Enterprise Technology Center" and enjoys a good reputation in the domestic magnetic materials industry. Similarly, Tongli Magnetic Materials Co., Ltd., established by Tianyuan Technology Co., Ltd. and Municipal Economic and Trade Development Co., Ltd. on the basis of integrating the bankrupt magnetic material factory of the original sulfur mine, has developed into a professional manufacturer with an annual output of 3,000 tons of high-grade permanent magnetic ferrite materials after a short period of three years of large-scale investment and technical transformation, and has entered the ranks of leading demonstration enterprises in Anhui magnetic material production base. In 2004, the enterprise realized the sales income16.8 million yuan and the profit and tax1240,000 yuan; From June to July this year, the sales revenue increased by 565,438+0.8% compared with the same period of last year, showing a good growth trend.
Maanshan Hi-Tech Magnetic Materials Co., Ltd. is a joint venture between Maanshan and Hong Kong, which integrates the production, management and research and development of high-performance permanent magnet ferrite materials. In recent years, we have focused on the development of special-shaped high-grade motor magnetic tiles with high added value and motor stator products for automobile fuel pumps, and all of them have been exported to Kane Company of the United States. In 2004, the company achieved sales income of 32.03 million yuan and earned foreign exchange through export of 1 15000 USD. In the first half of this year, the sales revenue was19.2 million yuan, and the foreign exchange earned by export was10.5 million US dollars, a substantial increase year-on-year. As a private enterprise specializing in the production of magnetic materials, the development of Xinyang Permanent Magnet Company can be called "miracle". By introducing technology and talents, this private enterprise has developed into a large-scale enterprise producing permanent magnet ferrite pre-sintered materials in China in less than nine years, with an annual output of 50,000 tons, ranking the top three in China and the first in Anhui Province. In 2004, this private magnetic material enterprise with only 200 employees realized the sales income of 6010.9 million yuan and the profit and tax of 3010.0 million yuan. In the first half of this year, Xinyang Permanent Magnet Company achieved a sales income of 3 1.38 million yuan, and continued to develop at a rate of more than 30%.
According to the relevant personage of the Municipal Development and Reform Commission, in the formulation of the 11th Five-Year Plan of our city, it has been determined that during the 11th Five-Year Plan period, a magnetic material industrial base led by Tianyuan Science and Technology, Xinyang Magnetic Materials and Hi-Tech Magnetic Materials will be built according to the development standards of provincial magnetic material industrial clusters, and the sales income of the magnetic material industry will be more than 3 billion yuan, creating a new growth pole of our city's industry.
