  • Patent number: 10835904
    Abstract: A process for trichome separation from plant matter deploys an ionic brine to induce oedemic transformation of disk cell to aid in releasing glandular trichomes. The brine can be agitated to further release disk cells from the plant tissue. The disk cell debris can be separated by sieving the larger trichomes and plant tissue particles that results from agitation and maceration. If the brine concentration is appropriately modified, the trichomes will float and the brine and the plant tissue fragments sink. The floating trichomes are then removed and rinsed and then dried or extracted further after drying.

  • Patent number: 10814334
    Abstract: A device for separating a metalliferous, lumpy mixture, with a conveyor belt and with a rotating drum in which a fixed magnet system with at least one magnet line is arranged. The separating effect of the device is improved and its complexity is reduced where it is provided that the magnets of the at least one magnet line are arranged such that their poles have the sequence NS SN or SN NS in the circumferential direction, as a result of which the ratio of the maximum radial magnetic flux density to the maximum tangential magnetic flux density on the belt surface, facing the material, in the region of the magnet system is greater than one and, owing to this, the electrically conductive particles are separated out into the first partial stream by radial force action (repulsion).

  • Patent number: 10807105
    Abstract: Apparatus uses engineered collection media to recover mineral particles in a slurry. The apparatus has a tumbler cell and a rotation device to rotate the tumbler cell. The tumbler cell has a container to hold a mixture of the engineered media and the slurry containing the mineral particles. The container is turned such that at least part of the mixture in the upper part of the container is caused to interact with at least part of the mixture in the lower part of the container. As such, the contact between the engineered media and the mineral particles is enhanced. The surfaces of the engineered media are functionalized with a chemical having molecules to attract the mineral particles to the surfaces so as to form mineral laden media. After the mineral laden media are discharged from the tumbler cell, the mineral particles can be separated from the engineered media by stripping.

  • Patent number: 10799916
    Abstract: Disclosed is a system for sorting copper-bearing ore to select portions having a desired target copper content. The system includes a first magnetic resonance analyzer for measuring the copper content of ore input into the system and a controller that controls a diverter to divert portions of the input ore to a collection path when the copper content meets or exceeds a predetermined cut-off value. The system also includes a second magnetic resonance analyzer to measure the copper content of the ore in the collection path. The measurements are then fed back to the controller where the controller can adjust the predetermined cut-off value above, up or down, to optimize the yield of ore with the targeted copper content.
