The present invention relates to pigments with improved and adjustable sparkling effect comprising A) a plate-like substrate of perlite coated with (a) dielectric material, and/or metal; and B) a plate-like substrate of mica, coated with (a) dielectric material, and/or a metal; and a process for their production and their use in paints, ink jet printing, for dyeing textiles, for pigmenting coatings (paints), printing inks, plastics, cosmetics, glazes for ceramics and glass. The pigments show an improved sparkle effect; in particular an attractive high sparkle intensity.

Pigments with improved sparkling effect

The present invention relates to a process for separating at least one first material from a mixture comprising this at least one first material, at least one second material and at least one third material, which comprises at least the following steps:

Cu&#x2014;Mo separation

A method for magnetic ore separation and/or dressing is provided, in which metalliferous recoverable materials are separated from conveyed metalliferous ore rock. The method may include producing a pulp including metalliferous recoverable material, executing a hydrophobizing reaction of recoverable material in the pulp, synthesizing a hydrophobized, magnetizable material in liquid suspension and adding this suspension to the pulp, causing an agglomeration reaction between hydrophobized magnetizable material and hydrophobized recoverable material to form magnetizable agglomerates in the pulp, separating the magnetizable agglomerates from the pulp, mixing separation products containing the agglomerates with a non-polar liquid insoluble in water and decomposing the agglomerates in the non-polar liquid into magnetizable material and recoverable material, separating the magnetizable material from the recoverable material, and removing moisture from the separation portion containing the recoverable material of the second separation stage to synthesize the recoverable material.

Method for continuous magnetic ore separation and/or dressing and related system

The present invention relates 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, which comprises the following steps:

Inorganic particles comprising an organic coating that can be hydrophilically/hydrophobically temperature controlled

The present invention relates to a process for separating at least one first material from a mixture comprising this at least one first material in an amount of from 0.001 to 1.0% by weight, based on the total mixture, and at least one second material, which comprises at least the following steps:

Enrichment of ores from mine tailings

The present invention relates to an agglomerate of at least one particle P which is hydrophobicized on the surface with at least one first surface-active substance and at least one magnetic particle MP which is hydrophobicized on the surface with at least one second surface-active substance, a process for producing it and also the use of these agglomerates.

Magnetic hydrophobic agglomerates

The present invention relates to a process of the invention for separating at least one first material from a mixture comprising this at least one first material and at least one second material, which comprises the steps:

Selective materials separation using modified magnetic particles

The present invention relates 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, which comprises at least the following steps:

Magnetic separation of nonferrous metal ores by means of multi-stage conditioning

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.

Method and device for extracting non-magnetic ores

The present invention relates 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, which comprises the steps:

Magnetic separation of substances on the basis of the different surface charges thereof

Processing rich ores using magnetic particles

A pigment of empirical composition(TiO)(ZnO)(SnO)(SnO)(REO)(AEO)(MO)wherein Preferably RE is selected from the elements Y, La, Ce, and Pr. The pigments are used as colorants for coloring paints, inks, plastics, and rubber.

Colorants comprising tin and rare earth elements

Use of luster pigments based on a platelet-shaped metallic substrate coated with a low refractive dielectric layer which does not absorb visible light, for pigmenting macromolecular materials.

Coated metallic luster pigments for pigmenting high molecular weight materials

Luster pigments having pronounced sparkle which are based on aluminum platelets which have been coated with iron oxide and have in the precoated state an average platelet size from 8 to 30 &#x3bc;m, an average platelet thickness from 300 to 600 nm and an aspect ratio from 15 to 70.

Luster pigments having a pronounced glittering effect

Goniochromatic luster pigments comprising at least one dielectric low-refractive interference-colored layer which includes a polar organic solvent which can interact with the layer material via functional groups.

Goniochromatic bright pigments
