AbstractAbstract
[en] A laboratory technique for determining the beach profile of hydraulically placed tailings is described. Three different tailings were tested, and the results indicate that varying the percentage solids or the nature of the tailings liquor has little effect on the resulting normalized profile. An evaluation of the likelihood of a tailings deposit having anisotropic permeability characteristics is also presented

AbstractAbstract
[en] The method of agglomeration of coal during hydraulic transportation, as compared to agglomeration in stirred tanks, is a new and very promising one. This paper describes the investigations that were conducted to define the optimum level of process variables such as bridging liquid concentration, particle size of the feed coal, flow rate in pipeline, and agglomeration time

AbstractAbstract
[en] The reclamation of 24 uranium mill tailings piles under the DOE Uranium Mill Tailings Remedial Action (UMTRA) program has provided an opportunity to compare the material properties of uranium tailings from different processing operations and different mineral belts. These results have shown that although the tailings have had different grinding processes and have come from different parts of the country, the material properties fit into a very close band of results. Although mill tailings material characteristics have been presented for other mill tailings, no such comparison exists for United States uranium mill tailings. This paper presents the compilation and comparison of data from uranium mill tailing piles data collected as part of the UMTRA program

AbstractAbstract
[en] This paper discusses a range of tailings disposal methods currently practiced in the mining industries in North America and Australia. These methods include various inpit disposal techniques; upstream, downstream and cent reline dam construction; and zoned earth fill embankment construction. The thickened tailings disposal method and the disposal of fine clays are also discussed. The importance of improving the depositional properties of tailings to enhance storage capacity, water reclaim, dam wall stability and final reclamation is stressed

AbstractAbstract
[en] In order to mitigate the detrimental effects that contaminants such as petrochemical and chemical spills may have on the environment it is critical to understand their transport. This paper presented an assessment of travel time for spills management using HEC-RAS water quality analysis on the Credit River Watershed. It is a 1000 km2 area of urban and rural landscapes drained by 90 km of the main Credit River. The study focused on the mixing characteristics of 5 stream reaches in the Credit River watershed. Dye tracing was done under three different flow conditions to obtain a longitudinal dispersion coefficient, which is a necessary parameter for predicting and modelling time concentration curves downstream of a spill. The longitudinal dispersion coefficient was input into the US Army Corp of Engineers, Hydrologic Engineering Centers River Analysis System (HEC RAS) to predict time concentration curves. The HEC RAS model produced average travel time close to those measured in the field after final calibration was completed.

AbstractAbstract
[en] An investigation is conducted to understand hydraulic transport characteristics of a solid-liquid mixture flowing vertically upward. Namely, this is the instance that solid particles are carried by non-Newtonian fluids in a slim hole concentric annulus with rotating inner cylinder. In this study a clear acrylic pipe was used in order to observe the movement of solid particles. The bulk axial velocities varied from 0.4 m/s to 1.2 m/s. The mud systems which were utilized included aqueous solution of sodium carboxymethyl cellulose (0.2∼0.4%CMC) and 5% bentonite solutions. Solid volumetric concentration and pressure drops were measured for the various parameters such as inclined annulus, flow rate, and rotational speed of inner cylinder. For both CMC and bentonite solutions, the higher the concentration of the solid particles are, the larger the pressure drops become
