The research and application status of vertical tailings silo in tailings gravity filling system

With the implementation of a sustainable development strategy in China, green mining technology has become the main focus of technical innovation in mining.The backfill mining method, due to its safety, high recovery ratio, and lower levels of damage to the surrounding environment, has meant that more mines have begun to build filling systems so as to implement backfill mining methods.As an integral part of a filling system, vertical silos can load, store, and discharge tailing slurry.The discharge of tailings from vertical silos is important, and its underflow concentration and slurry flow regime affect the efficiency and cost of filling.This paper discusses the research status and introduces the application status of vertical tailings silo.And further discusses the underflow research direction of vertical tailings silo in tailings gravity filling system based on existing research results.
