摘要： 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.

摘要： 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.
