  • Publication number: 20240100537
    Abstract: Methods and apparatuses for forming pellets, such as potash pellets, for example, are provided. The methods involve feeding agglomerate granules on to the operative surface of an assembly of rollers. The rollers are aligned to have parallel central rotational axes and there is a longitudinal gap between adjacent rollers. In order to form the pellets, the rollers are rotated to agitate and abrade the agglomerate granules on the operative surface of the assembly of rollers and form pellets.

  • Publication number: 20230358128
    Abstract: Processes and configurations for subterranean resource extraction are provided. The processes include installing borehole strings, such as by drilling a plurality of boreholes, for example, first and second boreholes, that extend from a surface region into a resource deposit. The first and second boreholes are situated adjacent to each other. Portions of the first and second boreholes laterally extend in a penannularly fashion and connect terminally at a nodal space situated within the resource deposit. Carrier fluid is injected from the surface along fluid paths defined by the boreholes to in situ leach resource materials from the resource deposit into the carrier fluid, and carrier fluid containing the resource materials is brought back to surface for resource extraction.
