Abstract:
The invention relates to a method for separating at least one first material from a mixture containing said at least one first material and at least one second material. Said method comprises the following steps: (A) a suspension of the mixture containing at least one first material and at least one second material and at least one magnetic particle is produced in a suitable suspending agent; (B) the pH of the suspension obtained in step (A) is adjusted to a value at which the at least one first material and the at least one magnetic particle have opposite surface charges such that the same agglomerate; (C) the agglomerate obtained in step (B) is separated by applying a magnetic field; and (D) the agglomerate separated in step (C) is split by adjusting the pH to a value at which the at least one first material and the at least one magnetic particle have identical surface charges in order to obtain the at least one first material.

The invention relates to luster pigments having a pronounced glitter effect based on aluminium platelets which are covered with iron oxide. Prior to coating, the average platelet size is from 8 - 30 µm, the average platelet thickness is from 300 to 600 nm and the ratio of the size to the thickness is 15 - 70.
Abstract:
The present invention relates to a method for separating at least one first material from a mixture containing said at least one first material and at least one second material, comprising at least the following steps: (A) bringing the mixture containing at least one first material and at least one second material into contact with at least one surface-active substance, optionally in the presence of at least one dispersant, wherein the surface-active substance bonds to the at least one first material; (B) optionally adding at least one dispersant to the mixture obtained in step (A) in order to obtain a dispersion; (C) treating the dispersion from step (A) or (B) with at least one hydrophobic magnetic particle so that the at least one first material, to which the at least one surface-active substance is bonded, and the at least one magnetic particle attach; (D) separating the attachment product from step (C) from the mixture by applying a magnetic field in order to obtain the attachment product and a mixture M1 depleted of the attachment product, and repeating the steps (A) to (D).
Abstract:
The present invention relates to a method for separating an at least one first substance from a mixture containing said first substance and at least a second substance, comprising the steps of: (A) bringing at least one magnetic particle and at least one bifunctional molecule, or an adduct of the two, into contact with the mixture containing the at least one first substance and at least a second substance so that an adduct is formed from the at least one magnetic particle, the bifunctional compound of the general formula (I) and the at least one first substance, (B) suspending the adduct obtained in step (A) in a suitable suspension agent, (C) separating the adduct present in the suspension of step (B) by applying a magnetic field, (D) optionally splitting the adduct separated in step (C) to obtain the at least one first substance, a corresponding adduct and the use of such an adduct for separating mixtures of substances.
