Facts
Who We Are - An Overview

Origins

In the 1960s, researchers in the Finnish paper industry discovered that adding pure talc to paper as a filler significantly improved its properties. The talc ore found in Finland is a mixture of magnesite and talc, so that a separating process (talc flotation) had to first be developed. The company Suomen Talkki Oy was founded in 1967 to commercialize this invention. In the years that followed, the company grew rapidly, acquired other talc producers and opened up further application areas.

Production

Today, we own talc mines in central Finland (Sotkamo, Vuonos) and operate highly efficient factories in Finland (Sotkamo, Vuonos) and the Netherlands (Amsterdam, Katwijk). We produce the brands Finntalc, Plustalc and Microtalc. These three product lines comprise highly specialised, valuable grades for paper, paints and coatings, plastics, cordierite ceramics, consumables and pharmaceutical products. Our great strength is our comprehensive know-how. Customers can count on our expertise in all areas – mining, purification, processing, logistics and application.

Global Presence

In 2025, Mondo Minerals re-established itself as a standalone talc company under its original name, following a change of ownership.

Headquartered in Amsterdam, with mining operations in Sotkamo and Vuonos (Finland), our goal is to offer our products worldwide. We have installed a global network of distributors.

Our manufacturing process and quality management make this possible: they guarantee consistent, uniform quality at all times and in all places.
