process for preparing calcium carbonate-containing composite particles, calcium carbonate-containing composite particles, and uses of a binder and composite particles

摘要

A process for preparing calcium carbonate-containing composite particles, calcium carbonate-containing composite particles, and uses of a binder and composite particles. The present invention relates to a calcium carbonate containing material having increased apparent density at equal or improved flowability, and a method of producing such material. The inventive process comprises the step of contacting a calcium carbonate-containing mineral powder with a solution or emulsion or dispersion of a binder.
