  Sun Chaohui, a member of the CPPCC and a grade-1 expert of panzhigang Research Institute, and representatives from all over the country gathered in the Great Hall of the people to discuss the plans for reform and development in the new era. On March 8, the reporter interviewed sun Chaohui on the relevant situation of his participation in the two conferences.

  "This year's government work report proposes that we should adhere to focusing on the development of economy on the real economy, promote the advanced industrial base and modernization of the industrial chain, maintain the basic stability of manufacturing industry, and transform and upgrade traditional industries."

  Sun said that the development of panzhigang has ushered in new historical opportunities. The Ninth Party Congress and the fourth Professional Congress of Panzhihua Steel proposed to build an industrial system of "1 + 1 + 4 + 4", put resource protection at the top position, and as a scientific and technological worker of Panzhihua steel, it is incumbent on him to actively make suggestions and suggestions for improving the comprehensive utilization of Panxi resources and ensuring the safety of national mineral resources.

  As an expert in the field of vanadium and titanium, sun Chaohui has made outstanding contributions to the rise of vanadium industry in China, which has become the first vanadium producing enterprise in the world. In recent years, he has focused on the comprehensive utilization of mineral resources. As early as the national meeting of the two countries in 2019, sun Chaohui proposed the proposal to change the division function of hongganan mining area from "mining area with important value to national economy" to "national planned mining area".

  Sun believes that the development of hongganan mine is the need to ensure the national resource security. At present, the four major ore sites of V-Ti magnetite in Panxi area are Panzhihua mine, Hongge mine, Baima mine area and Taihe mine area in Xichang. Panzhihua mining area has been mining for more than 50 years, so it is urgent to start the construction of the replacement mine. Hongganan mine, which has not been developed, is a mining area with the largest resource, the best mining conditions, detailed geological data and sufficient preliminary work. The ore is of good selectivity and high economic utilization value.

  The development of hongganan mine is the need of promoting the construction of the national strategic resource innovation and development pilot zone in Panxi. In March 2013, Panxi national strategic resource innovation and development pilot zone was established, which is the only comprehensive utilization test area approved to be established in China. Nearly half a century later, the exploitation and utilization of resources in Panxi has risen to a national strategy again. As the "leading" enterprise in the development and utilization of Panxi strategic resources, Pangang has always shared the fate with the country. After more than 50 years of development, Pangang is the only enterprise in the world to realize the comprehensive utilization of iron, vanadium and titanium resources of V-Ti magnetite. In recent years, panzhigang has been committed to building a world-class new material enterprise by focusing on the comprehensive utilization of Panxi resources, guided by the construction of new Panzhihua steel. With the support and help of the state, province, city and Angang Group, the research work on mining and beneficiation technology, metallurgical separation technology, vanadium chromium co extraction technology and high titanium type blast furnace slag extraction technology are focused on, forming a complete set of industrialization technology for comprehensive utilization of hongganan mine.

  The development of hongganan mine is the need to build a world-class vanadium titanium industry base and to build panzhigang into a world-class new metal material enterprise. In december2020, China Iron and Steel Industry Association organized an evaluation committee composed of 11 experts led by five academicians to evaluate the scientific and technological achievements of the research on key technologies for comprehensive utilization of hongganan mine resources led by Panzhihua Iron and Steel Co. Experts believe that this achievement further enriches and develops the comprehensive utilization technology system of vanadium titanium magnetite resources in China. The core technology reaches the international leading level, which can provide mature industrial technical support for the development and utilization of hongganan mine. After the comprehensive application, the low-cost and efficient utilization of iron, vanadium, titanium and chromium resources in hongganan mine can be realized. It is suggested that the development and utilization of hongganan ore resources should be started as soon as possible.

  Sun said that at present, the conditions for developing hongganan mining area are mature. It is suggested that the hongganan mining area be adjusted to "national planned mining area" in the national mineral resources plan (2021-2025) organized by the Ministry of natural resources, and developed by panzhigang, which has the complete set of industrialization technology of hongganan mine.
