Problems solved by technology

The stacking of this material not only pollutes the environment, but also causes a waste of resources
There are many valuable components in gold / molybdenum tailings, but the utilization of gold / molybdenum tailings is limited due to too little content
There are also a lot of literature on the reuse of slag, but most of the research is only on the separation and purification of individual components in gold / molybdenum tailings, and in actual production, it is difficult to separate and purify these components in large quantities
