General Trends in the Industrial Mineral Filler Industry

6

Industrial minerals are geological materialswhich are mined for their commercial value, which are not fuel, not sources of metals. They are used in their natural state or after benefication.

Industrial Mineral Fillers are a variety ofprocessed industrial minerals that may beirregular, fibrous or platy in shape and whichare typically used in large volume in paper, plastic, paint and rubber industries.

Left Topic

Quality and consistency:

- Are a must and driver of technological advancements and is a market desire

- Target quality of powders need top quality of processing equipment

- Highest availability of processing equipment is a must and a precondition of mineral producers from their market/customers

- Consistency includes quickest service, global service networkand easy maintenance
