Abstract: The present invention relates to a method of treating liquids with an alkaline earth metal silicate to reduce contaminants, a filtered liquid obtained by this method, the use of the method in the wine production process and a filter aid comprising an alkaline earth metal silicate.

Abstract: Minerals (e.g. silica- or silicate-based minerals) having good oil- and/or water-absorption capacities and/or good flowability, mineral composites comprising first and second mineral components having good oil- and/or water-absorption capacities and/or good flowability, methods of making said minerals and mineral composites and the uses of said minerals and mineral composites, for example in animal feed or fertilizer compositions.

Abstract: Methods for filtering fluid suspensions to obtain clarified fluids may include providing a fluid to be filtered, wherein the fluid contains solid particulate contaminants. The method may further include providing a constricted-fibre filtering device, providing a particulate filter aid, and filtering the fluid to be filtered and the particulate filter aid using the constricted-fibre filtering device. The method may further include collecting a filtered fluid and optionally filtering the collected filtered fluid again, using the constricted-fibre filtering device. A constricted-fibre filtering device may include an inlet for a fluid to be filtered and/or particulate filter aid, wherein the inlet includes a manifold leading to feeds arranged near or within fibres of the filtering device.

Abstract: A method of making magnesium hydroxide may include calcining a mineral source of magnesium carbonate to form magnesium oxide, and slaking the magnesium oxide in water. When the mineral source of magnesium carbonate further includes a mineral source of calcium carbonate, the calcination may be carried out such that less than about 20 wt % calcium oxide is formed following calcining and prior to slaking in water.
