Enhancing shear strength and handleability of dewatered clayrich
2023年10月15日 To facilitate dry stacking, coal tailings slurries were dewatered using either filtration or centrifugation methods, resulting in a semisolid form (cake) that can be safely disposed of The handleability and disposability of these cakes are greatly influenced by the selection of chemical aids (such as polymer flocculants) and the mechanical dewatering In "drystack" disposal, tailings are stored in dry form, typically by burial in a covered and lined pit In this regard, drystack storage, as illustrated in Figure 2, is similar to a modern, sealed landfill This method takes up much less space, is less susceptible to earthquake hazards, and does not require active water treatmentDewatering Tailings for Dry Stacking: Rapid Water Recovery by Hydraulic dry stacking (HDS) is an innovative concept for tailings management developed after the successful implementation of coarse particle recovery (CPR) technology in base metal sulphide operations CPR generates a well graded fine to coarse sand reject waste stream removed from the process circuit prior to final flotationInnovations in Tailings Management Hydraulic Dry StackingThe tailings management process using a tailings dam is less effective due to limited land and excessive water requirements Therefore, it is necessary to analyze alternative methods, one of which is the dry stacking method This journal is written using literature studies related to the themes and objectives of journal writingDry Stacking Sebagai Metode Penanganan Tailing Pengganti
