Mixing requirement for ultra paste tailings

چکیده
A controlling variable for a thickened tailings scheme design is the beach slope that will be formed by as they deposit. The mainly related to discharge flow rate and slurry rheology. latter will, in turn, dependent on solids concentration of thickener underflow. higher can achieved combining thickening filtration. objective still maintain pumpable self-distributing at storage facility (TSF), rather than having rely trucks or conveyors stacking systems manage ‘cake’, but one deposit steeper alone. use ultra paste has potential broaden range topographic conditions suit discharge. The option when portion separated dewatered more advanced dewatering unit (in this case filter presses). filtered cake then re-mixed with underflow stream. This paper presents study large copper mine which from series thickeners nominal tonnage 3,660 tph 59% would mixed 1,363 80% concentration. combined (ultra paste) discharged equally into two open channels (flumes) 63.5%. The ultimate goal adopting an ‘ultra paste’ produce homogenous consistency tailings, hence proper mixing occur. In based tests, requirement been assessed. also covers conceptual investigation natural turbulent (NTM) issues associated deposition paste, existing TSF. In conclusion, indicates NTM possibly occur only total are channel, not practical due limitations regards management. Hence, mechanical recommended case.

متن کاملLight Requirement for the Carotenoids Production by Mucor hiemalis
Objective Fungi produce many different carotenoids and some are attractive in medical and industrial sources. In this work the ability of Mucor hiemalis (PTCC 5292) to produce carotenoids in media with different nitrogenous and carbon sources and incubation with white, yellow, blue and red lights (15W, 220V, E27) against dark-grown were studied. Materials and Method The microorganism cultiva...
متن کاملRequirement for Revision of Virology Education for Medical Students
Background: Medical education should be considered as a dynamic process. If necessary, the program should be changed. Considering rapid advantages in the field of virology, it seems to be necessary to review and change the virology course of medical students. Therefore we decided to analyze the view of Iranian medical students of the quantity and quality of virology course. Methods: Medical stu...
متن کاملPreliminary Evaluation for Vacuum Membrane Distillation (VMD) Energy Requirement
The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...
