Hydraulic driven piston pumps for the transport of pastes and slurries in the mining industry

Abstract

More and more mines are using double piston pumps for conveying pastes, cakes and slurries. Stiff pastes are normally used for the stabilization of underground workings. Cement and ash are added to create a construction material with sufficient strength. For tailings and ore transportation above ground, slurries are produced and transported over long distances to deposits or preparation plants. In this article the author shows various job sites around the world where different materials are pumped, providing the relevant information about the pastes and slurries that were pumped, information about the paste preparation plants, advantages of the paste systems and when to use which type of piston pump. The article bases on the authoŕs presentation at the 3rd International Specialist Colloquium "Offset and Building Materials in Mining" on 5th October 2017 in Freiberg/Germany. © 2018, Bergbau-Verwaltungsgesellschaft mbH.
