Chengchao Iron Mine started construction in September 1958, and was completed and put into operation in October 1969 165438. The engineering design capacity is10.5 million tons of iron ore/year, which has been expanded to 3 million tons. This mine adopts a new technology of sublevel caving with high strength, high efficiency and low cost, and adopts advanced lifting equipment and efficient mining equipment for mining. The mineral processing technology matched with mining is advanced, and the iron metal recovery rate and iron concentrate grade (66.5%) have reached the national advanced level. Its main product, iron concentrate, has been rated as a high-quality product in the national metallurgical industry, and the product standard has reached the international advanced level. Its by-products are sulfur concentrate and copper concentrate, and its market prospect is very broad.

In the past ten years, Chengchao Iron Mine has taken the lead in implementing the contract responsibility system of joint production and the evaluation system of employees' work performance in WISCO Group, and achieved good results. The implementation of the unique system of mine information briefing, democratic dialogue, mine manager reception day and democratic information officer in this mine has gradually modernized the management. In 2 1 century, following the advanced trend of international metallurgical industry, enterprises put forward the idea of developing pellets, which was strongly supported by WISCO. The 654.38+200,000-ton pelletizing project completed in 2004 provided a modern production chain of mining-beneficiation-pelletizing-smelting for WISCO blast furnace.
