Drawing on more than 40 years of experience from the field, we have developed several optimized formulations to improve the performance of flotation collectors for calcite systems.

Innovative, Tailored Formulations

Our customized flotation collectors remove silicates and graphite from calcite to improve its brightness and reduce its abrasiveness as well as maximizing recovery and grade.

Natural calcite deposits contain various types of silicates and graphite. For applications like paper fillers, calcite characterized by a high level of brightness and low level of abrasive silicates is required.

Our formulations are tailored to aspects such as ore complexity, particle size of the feed and the preferred froth structure. In cases where discoloring minerals are present, we offer collectors that can be used independently or in combination with silica flotation collectors.
