Problems solved by technology

[0004] Although non-ferrous metal tailings have good potential utilization value, the current technical level cannot make good use of them, and the economic benefits are also very low
The treatment of non-ferrous metal tailings has not only seriously affected the development of the non-ferrous metal mining industry, but also with the increasing number of tailings, its management has become more and more difficult, and the workload has also increased greatly
It takes a lot of manpower, financial and material resources to deal with these non-ferrous metal tailings, and it also causes environmental pollution, waste of resources, potential safety hazards, land occupation and other major social hazards.
[0005] Usually, non-ferrous metal tailings contain other common and associated radioactive elements, such as uranium, thorium, radium, etc. If these tailings containing radioactive elements are made into building wallboards for use, they will bring harm to environmental safety and human health. potential hazard
