Our Mission:

In the field of mining and metallurgy industry, China, as a major consumer of mineral resources, has to try all kinds of way to process and extract low grade and complicated minerals, which has contributed greatly to improve our research level.

The booming of Chinese economy has given rise to many huge mining and metallurgy projects in China, some of them are even world's most complicated and biggest projects, which has given us the most precious experience on engineering designing and project operation.

At the same time, as the world's factory, China provide its customer all over the world the most price competitive and excellent performance mining and metallurgy equipment, which can help significantly reduce operation and maintaining cost.

As diligent and hardworking Chinese people, we never stop making progress, new innovations, and breakthroughs. This ancient and rapid developing country now extend its willing to share with the whole world its experience and capability in the mining and metallurgical engineering field and provide its customer the most competitive equipment and service, which, is also the mission of UNIONSUM.
