  • Concentrating graphite particles by agglomeration with hydrophobic magnetic particles
    Patent number: 11420874
    Abstract: A process for concentrating graphite particles comprising a) providing a feedstock which contains the graphite particles and an undesired material, b) adding hydrophobic magnetic particles to the feedstock which results in a loaded feedstock containing agglomerates of the magnetic particles and the graphite particles, and c) separating the agglomerates from the loaded feedstock by a magnetic field which results in isolated agglomerates.
    Type: Grant
    Filed: September 18, 2018
    Date of Patent: August 23, 2022
    Assignee: BASF SE
    Inventors: Wolfgang Rohde, Andreas Luz, Michael Mentges, Oliver Kuhn, Rodrigo Enrique Munizaga
  • Concentrate quality
    Patent number: 10807100
    Abstract: The present invention relates to a process for the separation of at least one valuable matter containing material from a dispersion comprising said at least one valuable matter containing material and at least one second material. The process according to the present invention comprises at least the steps (A) to (E) and the optional steps (F) to (H) which are described herein.

  • Silicon comprising polymer coated particles
    Patent number: 10300496
    Abstract: The present invention relates to core-shell-particles, wherein the core comprises at least one metal, or a compound thereof, or a mixture of at least one metal or a compound thereof and at least one semimetal or a compound thereof, and the shell comprises at least one silicon comprising polymer, to a process for the preparation of these core-shell-particles, to the use of these core-shell-particles in an agglomeration-deagglomeration process, in particular in chemical, physical or biological test methods or separation processes, decontamination processes, water purification, recycling of electrical/electronic scrap or gravity separation, and to a process for separating at least one first material from a mixture comprising this at least one first material and at least one second material.
