Abstract: In order to improve the service life and operation efficiency of the key conveying equipment in the concentrator and reduce the maintenance cost，aiming at the problems of serious wear and frequent re‐ placement of traditional rubber pump and alloy pump under the condition of high abrasive slurry，taking Longqiao Mining Concentrator as the research object，the application of ceramic pump in five key process‐ es，such as primary grinding，ϕ65 m thickener，sand washing pump，regrinding and total tail，was system‐ atically analyzed，and the operation cycle，maintenance frequency and procurement cost of ceramic pump and traditional pump were compared，the economic benefit quantitative analysis is carried out. The results show that the service life of the ceramic pump in each process is significantly prolonged，the direct econom‐ ic benefit is more than 800 thousand RMB，and the maintenance workload and downtime are greatly re‐ duced. The ceramic pump has significant technical advantages and good economic feasibility in the high�abrasion environment of mineral processing，which improves equipment reliability and production continu‐ ity. The application can provide experience and technical support for similar mining enterprises.
