Imerys

• Imerys of France purchased Rio Tinto’s talc operations on August 1st.

• Imerys mines rare resources and turns them into specialities that improve the products and processes of its customers in industry and construction.

• Imerys has an unmatched portfolio of resources in items of diversity and geographic balance and an excellent grasp of large-scale mineral conversion technologies.

• Its innovation capability enables it to design high value-added solutions for its customers.

Imerys, Luzenac Group

• With an annual production of one million tonnes, Luzenac Group is the world leader in talc processing with total market share of approximately 15%. Imerys therefore broadens its functional offering for technical applications and in a wide range of industrial markets.

• Thanks to its lightness and strength in Plastics & Polymers, talc can be used to reduce vehicle weight, for example:

• Incorporated as a filler, it improves the quality of Paints & Coatings, through its matting, anti-corrosion, anti-cracking and anti-mold properties.

• Used in the Paper-making process, it makes recycled paper whiter, in particular;Talc’s also contributes to other applications. Its thermal resistance and mechanical strength allows Ceramics manufacturers to lower their firing temperatures and limits thermal distortion.

• Talc also improves quality of Health and Beauty Products.

Today's Applications for Talc

• Talc is a rock formed over many millions of years. It is water repellent, inert, platy and the

softest mineral on Earth.

• 15,000 years ago, cave dwellers used talc as an ingredient in their paints.

• The Chinese were already using talc in glazed pottery (618 to 907).

• Talc has been used in cosmetics for thousands of years. The ancient Egyptians and the

Vedics of India were using it to lighten their skins as much as five thousand years ago.

Around the same time, the Chinese were making face powders from rice powder mixed

with ground minerals such as talc and kaolin.

• There are hundreds of talc deposits of various sizes in activity throughout the world. Each

talc deposit has its own features, its own geological signature. Talc can be white, grey,

pink, blue, violet, green and even black.

• Talc is used in the manufacture of a myriad of everyday products including animal feed,

automobiles, cables, sweets, ceramic tiles, chewing gum, cosmetics, fertilizers, foundry

technology, olive oil processing, paint, paper, pharmaceuticals, plaster, plastics, printing

inks, putties, refractories, roofing, sanitary ware, tyres and of course body powder.
