Abstract: A pigment is disclosed wherein the pigment includes a platy substrate or uniform platy substrate coated with an odd number of layers of alternating layers of high or low refractive index material, wherein each layer has a refractive index that differs from adjacent layers by at least 0.2; and the pigment has from about 40 to about 100% reflectance of light having a wavelength of 280 nm to 400 nm. Processes for making and using the pigments are also disclosed. These pigments can find application in paints, plastics, cosmetics, glass, printing inks, and glazes.

Abstract: In a device and a method for extracting non-magnetic ores from a pulp comprising non-magnetic ore particles and having a solid fraction of at least 30 mass percent, the pulp flows continuously through a reactor in the direction of flow and magnetic or magnetizable magnet particles that form ore magnetic particle agglomerations with the non-magnetic ore particles are added to said pulp. The ore magnetic particle agglomerations are moved by a magnetic field into an accumulation range of the reactor, and are then discharged out of reactor range and separated into ore and magnetic particles. In a device and a method, the separated magnetic particles are treated, in particular hydrophobized, such that during a new interaction with non-magnetic ore particles, new ore magnetic particle agglomerations are formed. Accordingly, a high yield of ores can be obtained and the mine can be operated in an economical and environmentally friendly manner.
