Wulan Mine, Manchuria Co., Ltd., China Railway Resources Group (CRRG)

Country:

Mongolia

Project type:

China Railway Resources Group general contracting project. The technology of paste lining with full tails is used. Productivity of the system is 70–90 m³/h, transport distance is 2400 m.

Project results:

Seamless transport of plum (water), energy savings reached 30%. After the technical modernization of the superplasticizer (water-reducing additive) feeding system, not only the labor intensity was reduced, but also the smooth circulation of the tails was guaranteed. Due to the constant optimization of the proportions of concrete, superplasticizer and tails, while complying with the requirements for the strength of the lining, the cost of the lining was reduced as much as possible - almost by twice .
