A method of increasing the strength of a carbonate rock is described. The carbonate rock may be located within a subterranean carbonate formation or may be located on a building exterior. The method involves contacting the carbonate rock with a composition comprising a zinc salt or a silicon alkoxide. This may increase the hardness of the carbonate rock by 10% or more.

The present invention relates to a method for the production of granules comprising surface-reacted calcium carbonate, as well as to the granules obtained thereby and their use.

The use of inhibitory calcium carbonate as additive for a composition containing at least one polymer different from cellulose, wherein the inhibitory calcium carbonate is obtainable by means of a method in which calcium carbonate particles are coated with a composition comprising, based on its total weight, at least 0.1% by weight of at least one weak acid.

Further described is a composition containing at least one polymer different from cellulose and inhibitory calcium carbonate, wherein the inhibitory calcium carbonate is obtainable by means of a method in which calcium carbonate particles are coated with a composition comprising, based on its total weight, at least 0.1% by weight of at least one weak acid.

Preferred application areas of the composition encompass its use in food packaging, in products for agriculture and horticulture, in catering articles, in office articles, in medical technology products, in composites and/or in 3D-printing methods.

This disclosure describes formulations and methods for dust control, for example, coal topping, a term which refers to the application of liquid products to the top of coal loads, such as those in open topped coal hopper railcars as commonly used today to transport coal. Disclosed herein are asphalt-based emulsion formulations that accomplish dust control during industrial operations in which dust handling is required.

The present invention concerns a process for manufacturing white pigment containing products. The white pigment containing products are obtained from at least one white pigment and impurities containing material via froth flotation.

Inorganic particulate compositions containing inorganic particles associated with a copolymer of a hydrophilic monomer and a hydrophobic monomer associated with the inorganic particles are provided. The particulate composition satisfies at least one of the following properties: a BET surface area of the inorganic particles is greater than 8 m.sup.2/g, a Hegman value of the inorganic particles is 75 microns or less, and a rate of water loss from the composition upon drying from a moisture level greater than 2% wt % is at least 30% greater than a composition having a corresponding content of a polyacrylate polymer associated with the particles. A method to prepare the composition and formulations for inks, paints, coatings and filled polymeric articles containing the inorganic particulate composition are also provided.

The present invention relates to the technical domain of additives for aqueous high solids suspensions of mineral materials. The inventive additive comprises specific primary amines and is used for increasing the pH-value of the suspension and/or for increasing the wettability of the mineral materials.

The present invention refers to a surface-reacted calcium carbonate having a volume median particle size d.sub.50 from 0.1 to 90 μm, wherein mint oil is adsorbed onto and/or absorbed into the surface of the surface-reacted calcium carbonate as well as the use of such a surface-reacted calcium carbonate for stabilizing mint oil.

The present invention relates to a process for preparing a surface treated filler material product with succinic anhydride(s), a surface treated filler material product, a polymer composition, a fiber and/or filament and/or film and/or thread comprising the surface treated filler material product and/or the polymer composition, an article comprising the surface treated filler material product and/or the polymer composition and/or the fiber and/or filament and/or film and/or thread as well as the use of a mono-substituted succinic anhydride for decreasing the hydrophilicity of a calcium carbonate-containing filler material surface and the use of a surface-treated filler material product for initiating the crosslinking reaction in epoxide resins.

A breathable film is described having a basis weight from 1 g/m.sup.2 to 10 g/m.sup.2, a process for producing the breathable film and use of a surface-treated filler material product as filler in the breathable film. Finally, an article is described that includes the breathable film as well as the use of the breathable film in hygienic applications, medical applications, healthcare applications, filtration materials, geotextile products, agricultural applications, horticultural applications, clothing, footwear products, baggage products, household applications, industrial applications, packaging applications, building applications, or construction.
