Tailing Sand- Energy Saving & Environmental Protection

Currently, developing countries are at the peak of large-scale civil engineering construction, and strongly demand for construction sand and gravel . As soon as possible to develop a new technology to recycle the mining Tailings infrastructure can not only help to ease the over-exploitation of natural gravel, but also consolidate and develop the environmental protection, improve resource utilization, which can be described as killing two birds with one stone.   Tailings generally refers to the stripping of the surrounding rock, low-grade rocks, discarded waste in the process of extraction and processing of metal ores, non-metallic mine minerals. These tailings are generally piled up around the mines , which occupy the land, damage the land surface, damage the soil, threat biological safety , blockage river bed , pollute water and blow dust. If annual discharge of tailings is used to produce artificial sand and gravel , it can address the needs of 20.4 million tons of ...
