  • Publication number: 20230319162
    Abstract: A method performed by a health service configured to update a domain name system (DNS) to enable clients, which use the DNS, to allocate service requests to a plurality of service instances which provide the service wherein each service instance comprises a microservice architecture is presented. The health service requests outcome data from at least one of the service instances, and calculates a status indicator for the service instance, wherein the status indicator is calculated based on results from internal recursive checks performed throughout the microservice architecture of the service instance and heuristic calculations performed on service request performance data. After calculating the status indicator, the health service triggers a dynamic update to the DNS according to the calculated status indicator.

  • Patent number: 10988826
    Abstract: This invention relates to a hydrometallurgical process for the recovery and separation of valuable precious, base or rare elements such as platinum group metals (PGMs), gold or silver, and other valuable base and rare metals such as nickel, cobalt, copper, rare earth elements (REE), yttrium and scandium, as well as uranium, thorium, manganese, zinc, cadmium, molybdenum, titanium, tin, and other minor elements such as vanadium, germanium and gallium from a feed material comprising ores, concentrates and other materials. In particular, the process comprises quantitative removal of additional base, rare and gangue elements for increased efficiency of further treatment of the solids for valuable metals recovery and/or recycling and/or separation of valuable metals from pressure leach residue and may be integrated into one or more existing valuable element extraction processes.

  • Patent number: 9540706
    Abstract: This invention relates to a hydrometallurgical process for extracting platinum group metals (PGMs), gold, silver and base metals from a flotation concentrate (10) containing sulphide minerals such as pentlandite and chalcopyrite, along with pyrite and pyrrohotite. The process includes a modified pressure oxidation step (12) to selectively separate base metals into sulphate medium (14), from the PGMs. The modified pressure oxidation step (12) partially or completely oxidizes sulphide minerals to produce a product slurry (14) containing base metal sulphates in solution and a solid residue containing PGMs along with sulphate and elemental sulphur. The solid residue is subjected to a thermal treatment (18) to remove sulphate and elemental sulphur from the solid residue, and to condition the PGMs to be soluble in chloride medium. The treated solid residue is the subjected to PGM recovery by leaching in chloride leaching medium (20) to recover the PGMs.

  • Patent number: 9300811
    Abstract: Various technologies described herein pertain to retaining content of a conference call for accelerated replay. The content of the conference call can be recorded. Further, establishment of a connection of a participant to the conference call can be detected. For instance, the connection can be established with a computing device of the participant. Moreover, the establishment of the connection of the participant to the conference call can be detected subsequent to initiation of the recording of the content of the conference call. Responsive to detection of the establishment of the connection of the participant to the conference call, at least a portion of recorded content of the conference call can be transmitted to the computing device for playback at a playback speed that is greater than a speed at which the content is recorded.
