Nitrogen and Phosphate in Vadose Waters in Heber Valley
During the last decade best management practices have been gradually implemented in Heber Valley to maintain and enhance the qualities of surface waters that flow into Deer Creek Reservoir....
Overview of Acid Mine Drainage Control Strategies
Since 1970, regulations requiring proper overburden sampling techniques to obtain representative geologic profiles and outline specific overburden analysis to determine acid-producing,...
An Offshore Borehole Mining Experiment: Its Operational and Environmental Implications
The Continental Shelf Division of the Marine Minerals Technology Center (MMTC), conducted a miniborehole mining experiment offshore Georgia in June 1990. A remote placer drill developed...
Expansion of the Electro-Coal Transfer Terminal
This paper briefly describes renovation and expansion of the coal and phosphate marine terminal in Davant, La. The program included: replacement of existing berths damaged by marine accident;...
Experimental Verification of a Unified Chlorine-Ammonia Reaction Model
A model of the reacting aqueous chlorine-ammonia system is proposed which describes equally well the rapid 'breakpoint' oxidation of ammonia or the slow decomposition...
The Theory of One-Dimensional Consolidation of Saturated Clays
The theory of nonlinear finite strain consolidation is reviewed. A modification of the effective stress equation to account of settling and consolidation as a unified phenomenon is proposed....
Validation of Consolidation Properties of Phosphatic Clay at Very High Void Ratios
The void ratio-effective stress and void ratio permeability relationships for phosphate slime mine tailings were measured by several methods. The measurements were used in nonlinear finite...
Waste Phosphatic Clay Disposal in Mine Cutsr
Research was undertaken to assess the applicability of waste clay disposal back into phosphate mine cuts. The pit was monitored for two years with measurements of clay surface elevation,...
Centrifugal Modeling of Phosphatic Clay Consolidation
As a by-product of beneficiation, quantities of dilute clay slurry are produced which are stored in retention ponds. One method of accelerating consolidation is to surcharge the clay with...
