In early February 2004, "15" national scientific and technological project "Research on new technologies boron iron ore blast furnace separation" through acceptance. The successful research on the separation technology of boron iron ore blast furnace provides a new technical approach for the rational utilization of boron iron ore resources. It is of great significance for revitalizing the old industrial base of Liaoning and prospering the economy of Liaoning.

Boron is an important chemical raw materials and alloys. Liaoning Province in China is rich in boron resources, and 90% of the raw materials needed for boron chemical industry in the country are supplied by Liaoning. However, after years of development, Liaoning's boron- magnesium ore (white ore) has been depleted, and a large number of boronite (black ore) resources have been difficult to use economically and efficiently because of the difficulty in separating boron and iron. In recent years, due to the rapid growth of market demand for boron, the local phenomenon of indiscriminate mining of boron and iron resources, and the abundance of poverty has become increasingly serious, resulting in great waste of resources.
The iron-boron separation test of the 28M 3 blast furnace of Boronite carried out in this project, the magnesium oxide in the slag is enriched to about 40%, the blast furnace can be antegrade, the furnace condition is stable, the slag iron flow is smooth, and the iron-boron separation is good. This is the blast furnace smelting technology. A major breakthrough. For low-grade refractory iron-bearing boron ore, iron-boron separation is carried out in a common ironmaking blast furnace to obtain boron-containing pig iron and boron-rich slag. The boron-rich slag contains B 2 O 3 ≥12%, which is the production of boric acid and borax. The high-quality raw materials obtained at the same time can be directly used as raw materials of boron-iron alloy, which simplifies the preparation process of boron-iron alloy, and the utilization rate of boron is increased by more than 25%, which is a major advancement in the comprehensive utilization technology of boron iron ore resources. This achievement provides a new and effective way for comprehensive development of boron iron ore resources, which can make the “staying mine†into a usable resource for many years, thus greatly improving the shortage of boron resources in China and promoting the boron industry and related industries in China. development of. At the same time, the achievement also provided a technical basis for the establishment of a boron-based metallurgical, chemical, and new material production base in Liaoning, forming a new economic growth point for the old industrial base in Liaoning.
