        Key national special research and development plan special projects      

"Large scale industrial solid waste collaborative preparation of low-cost cementitious materials and application technology" project China new material academy takes the lead In conjunction with Wuhan University of Technology, Hubei University of Technology and University of Science and Technology Beijing, the top 10 research institutes and enterprises in the field of solid waste resources have been preparing for more than half a year. After several rounds of rigorous expert reviews, replies and fierce competition, they finally won in April 2020. National key research and development plan "key projects of solid waste utilization" This indicates that the competent departments and industries in the country highly recognize our company's core competitiveness and application demonstration in the field of solid waste recycling.


       Commissioning of key special demonstration lines

In May 31st, our company developed and designed. One of the national key research and development plans, one of the key demonstration projects of solid waste recycling. The new type of cementing material for the mine is officially put into operation with the annual output of 700 thousand tons (including mortar line transformation).

This project takes the water quenched slag of general industrial solid waste as the main raw material, and the new cementitious material produced by material design and innovative production process can completely replace cement for downhole cemented filling. Compared with cement, the consumption of cementing material is reduced by less than 50%, the actual filling cost is greatly reduced, and the utilization of tailings is increased.

       The filling material production line of the mine has large capacity, advanced technology and high automation. It meets the needs of low cost and high performance cemented filling in the eight major mines of the owner Tongling Nonferrous Metals Group Holdings Co. It solves the two difficult problems of filling mines with high sulfur content and super fine tailings cemented backfill. It can save a lot of filling cost for Tongling nonferrous metals and solve them at the same time. The tailings discharge and mine safety problems.

During the implementation of the project, the project team will work overtime to optimize the epidemic prevention and control, and do a good job in the work of rehabilitation. One month ahead of schedule. Trial production! As Tongling City, Anhui Province Pilot project of "no waste city" construction The support project will greatly enhance the disposal capacity of general industrial solid waste such as smelting slag, tailings and other industrial wastes in Tongling. It is of great significance to the mine ecological environment management in Tongling.
