More information :

Only a part of the whole ore taken from underground contains the required minerals. The sterile part (or waste rock) is reused to fill in the site mined or excavated areas. Concrete/surface cement plants will produce several types of mine paste backfill with this sterile part : Cemented paste backfill (CRF) consisting of rocks, external sources aggregates or sterile parts coming from the foundations – cemented hydraulic backfill (CHF)- Cemented paste (Cement Paste F), last backfill system, using a complete tailings streams coming from the mine wastes or excavated dry residues.
These cemented backfill means are adhesive and abrasive. The valves used in these units must deals with abrasion, erosion, corrosion issues and ensure a cement procurement without blockage when tanks are drained. Guichon valves proposes some process valve solutions adapted to these challenging operating conditions, such as cementing valves and shut-off valves.
