The leader of green and intelligent mines

In the field of mine engineering design, we are committed to building green and intelligent mines. Representative projects include: Dahongshan Copper and Iron Mine, Hualian Zinc &Indium Stock Co., Ltd. Lead-Zinc and Tin Mine, Beiya Gold Mine, Lanping Lead-Zinc Mine, Lala Copper Mine, etc.

Excellent mining project

1 Dahongshan Iron and Copper Mine

Dahongshan Iron Mine project is designed to fully tap the resource potential of Dahongshan and realize large-scale mining with a production capacity of 18.8 million t/a-20 million t/a, making it the largest underground metal mine in China. The project won 18 national, provincial and ministerial excellent engineering design awards.

The design of the mineral processing, equipment, configuration, plant and related facilities of the first and second phases of Dahongshan Copper Mine is suitable for the nature of the ore, the process is simple, and the indicators are advanced (reaching the leading level in China).

4 Lanping Lead-Zinc Mine

The proven lead + zinc metal reserves of Lanping lead-zinc mine are 15.4761 million tons. Lanping lead-zinc mine is the largest lead-zinc deposit in China and the largest lead-zinc mine in Asia, with a potential economic value of 100 billion yuan. KERI established the Lanping Project Department in the 1980s to provide comprehensive technical services for the Lanping lead-zinc mine in mining, processing and smelting.

5 Lala Copper Mine

Lala Copper Mine has developed into a large-scale non-ferrous mine with an annual mining scale of 1.65 million tons, and is the second batch of national green mines.

KERI undertook consulting services such as preliminary design, construction drawing design, construction drawing cost, digital integrated mine design and construction. The production scale is 4,000t/d and 1.32 million t/a. The main process plan adopts a number of core technologies and experiences of KERI to ensure the project is highly efficient, advanced, safe and environmentally friendly.
