  • Froth flotation with anisotropic particle collectors
    Patent number: 11413629
    Abstract: In one example, a method includes providing a pulp composed of a combination of particulate materials including particles of a target material. The pulp is mixed with a collector composed of anisotropic particles having at least two separate spatial domains that have different physiochemical properties, and the mixture of pulp and collector is fed into an aqueous solution containing air bubbles.
    Type: Grant
    Filed: September 23, 2019
    Date of Patent: August 16, 2022
    Assignee: International Business Machines Corporation
    Inventors: Julia Baldauf, Alexe Bojovschi, Benjamin S. Mashford, Christine Schieber, George Yiapanis

  • Flowfield sensors for monitoring liquid flow
    Patent number: 10252920
    Abstract: Data relating to fluid dynamics is obtained using a flow field sensor that measures acceleration and angular velocity of the sensor on three axes. Ballast control allows the sensor to obtain neutral buoyancy within the fluid. The sensor is effective in opaque fluids and closed containers as data is stored in a removable memory. Froth flotation systems are among the applications for the sensor. The small size, the geometry, and the center of mass of the sensor allow it to follow the flow field in a vessel without material disruption of the flow field or weight-induced angular displacement.
