FLSmidth to deliver tailings solution to Rajasthan mine of HZL
FLSmidth to deliver tailings solution to Rajasthan mine – For a proper dry stack tailings arrangement and a glue fill plant to a Hindustan Zinc Ltd (HZL) lead-zinc mine in Rajpura Dariba, FLSmidth will convey a coordinated
arrangement that will guarantee ecological maintainability and critical cycle water recuperation, just as decrease the impression of the tailings storeroom.
The new request, which was reserved in 4Q20, incorporates configuration, designing, acquisition, supply of gear and the authorizing for coordinated dry tailings and stacking alongside tailings glue fill plant. FLSmidth will likewise supply two programmed channel squeezes (AFP-IVTM), two E-Disk channels and one 26 m dia. high-thickness thickener as the fundamental bits of gear. The venture is relied upon to be finished by February 2022. This new request follows a past tailings-related request for HZL at their Zawar mine site in 2018.
HZL works beneficiation plants at Rajpura Dariba and Sindesar Khurd, which both release tailings (mine waste) to similar tailings lake. The tailings dam was arriving at limit with respect to regular wet tailings statement thus HZL required an approach to determine this issue. The arrangement they required would include making a little dry-stack tailings territory with limited ecological and actual impression and furthermore a strategy to refill the mine by utilizing a changed dry channel cake blend.
By picking FLSmidth’s crossover innovation – a mix of the E-Disk channel and the AFP-IV Automatic Pressure Filter – HZL will currently have the option to accomplish this and recuperate around 85% of cycle water, which can be reused by the cycle plant situated at the mine site with least working and capital costs. The cake from the E-plate channel will contain beneath 16% dampness and can be utilized for mine refilling, while the cake from the programmed channel press, with underneath 12% dampness, can be stacked on a superficial level in a protected and reduced way.
The arrangement will likewise altogether lessen mechanical water utilization, something that is of increased significance in water-scant zones, for example, Rajasthan. The site will likewise have zero gushing release, further boosting its practical mining objectives with another solid verification point for the quality and adaptability of our innovation for filtration and our designing answers for following administration. This undertaking settle the client’s test through ideal use of accessible space and guarantees the glue refill prerequisites are met with the most minimal conceivable working and capital expenses. Significantly, it likewise makes sure about an elevated level of reusable water for the mine site, which helps their supportability endeavors and supports our own MissionZero desire,” remarked Manfred Schaffer, Mining President, FLSmidth.
