    Thrills and spills - Swell times for absorbent minerals

    01 May 2002

    Absorbent minerals have a valuable role in improving the environments in which we live, work, and play. Their natural ability to retain fluids of all types while remaining inert, and to do so at a low cost, makes them the favourite product over other synthetic, organic or inorganic products in many industrial and environmental applications. Spillage control is a traditional but solid market for mineral absorbents; soil amendment is a market expected to have a promising future; and the applications for minerals in landfill sealing are diversifying, as increased recycling slows growth in this sector.

  • Abracadabra - Has mica lost its magic?

    01 May 2002

    The history of mica stretches back over 4,000 years to a time when it was believed to have magical medicinal powers. According to a mica producers brochure, the Hindustani words for the mineral were abrak and abhra, which chanted together may be the etymological origin of abracadabra. Ground mica provides the magic for a variety of applications and is a mineral in the vanguard of automotive plastic and pigment developments, although negligible market growth and static or declining pricing have become familiar bedfellows for mica producers over the last 18 months. But despite the economic slowdown, producers remain bullish about the future as they seek to concentrate on higher value added markets

This article provides an insight into recent trends in the flat glass market sector.

  • Quality feldspar production at Cine Akmaden

    01 May 2002

    Feldspars are indispensable raw materials for ceramics and glass industries due to their alkali (Na2O, K2O) and also alumina (Al2O3) contents. Although the earth’s crust mainly consists of feldspar, being 25.6% in various grades as rock forming minerals, hitherto only some, namely albite, orthoclase and microcline have been exploited for glass and ceramic making.

  • Land of the Giants - The European lime industry

    01 May 2002

    The European lime industry is a mature one, with little change in production, consumption and technology over the past five years. Today the industry is dominated by a handful of huge multinational companies, which tower over the industry, commanding production and marketing, as they continue to grow and consolidate the European industry. However, subtle changes in lime consumption are starting to emerge, with the environmental market at the centre of growth.
