Abstract: A process is disclosed for disposing mineral processing tailings. The process includes the step of treating the tailings to produce a flowable paste including a mass comprised of particles at least approximately 15% of which are less than 20 microns in diameter. The process further includes the step of preparing an unconfined ground surface tailings disposal site by grading a selected site to produce a substantially level paste receiving bed. The flowable paste is then deposited onto the paste receiving bed from a discharge station to flow by gravity to a natural angle of rest of between approximately 1° and 10° slope. The paste is allowed to consolidate from flowable to a solidified state, retaining the natural angle of rest. Overburden is then placed over the solidified paste. The process is particularly useful in ore processing using cyanidation in which cyanide destroying chemicals are used at or prior to preparation of the flowable paste.

Abstract: Whether or not the provisioning of a given BRI is properly administered is determined by providing a collection of processes which exercise the known network provided supplementary services in a predetermined fashion. Specifically, a predetermined, i.e., algorithmic, process is employed to examine an administration database to determine which DSLs are to support supplementary services and, then, the process invokes a plurality of processes which attempt to activate the expected supplementary service. The basic mode of operation is to generate a connectivity context in which the supplementary service can be invoked and, then, cause the service to be invoked. ISDN messages are transmitted to the network over the D channel of the given BRI both to establish the service context and, then, to invoke the supplemental service. By analyzing the processes and ISDN messages the system can determine if the desired supplementary services are available, and the results of the analysis are recorded and made available to an operator.

Abstract: The present invention is directed to a new and improved wellbore packing device for use in isolating zones within a subterranean wellbore and to methods for applying the packing device in a cased-hole application. The present invention is directed to a new and improved inflatable or external casing packer (ECP) for use in cased wellbores. A hybrid inflatable packing element design in an ECP is presented, having in a single-unit, anchoring and sealing sections for application in cased wellbores using a phase change inflation medium such as cement or epoxy ar the like. The present invention overcomes limitations of existing prior art ECP's since these prior art ECP's are not capable of providing both sealing and anchoring packing elements in a single unitized design in size and access restricted wellbores. The inflatable elements comprise a sealing section that uses a noncontinuously reinforced elastomeric element with anti-extrusion ribs at its ends. When filled with the inflation medium, a frictional, radial force sealingly engages the elastomeric element with casing wall. An anchoring section is also provided that uses a continuously ribbed elastomeric bladder element. The steel ribs on the surface of the elastomeric element engage in metal-to-metal contact with the casing wall as the inflation medium exerts a Frictional, radial force. Any trapped. wellbore fluid between the sections escapes via the pathway between the ribs. A method for use of the hybrid ECP is also disclosed. More specifically, a method for use of the hybrid inflatable packer is a cased hole environment with a phase change inflation media is presented.
