Sales of Bentonite, Fuller's Earth and Allied Clays to Exceed 164 Million Metric Tons by 2010, According to New Report by Global Industry Analysts, Inc. Maintaining modest growth, the world bentonite, fuller's earth and allied clays market is forecast to exceed 164 million metric tons by 2010. Global drilling rig count market is expected to spur growth in bentonite and related clays market.
San Jose, California (PRWEB) March 10, 2008 -- Clay is a group of fine-grained hydrous crystalline minerals (mainly comprises silica, alumina, and water) found naturally in the earth. These minerals consist of silica, alumina, and water and additionally substantial quantities of iron, alkalis, and alkaline earth metals. Clay minerals are broadly classified into two groups, specialty and kaolinitic clays. Specialty clay includes bentonite whereas kaolinitic clays include fire clay, ball clay, kaolin and stoneware clay. These minerals occur with calcite, quartz, dolomite, gypsum, feldspar and iron oxide.
World bentonite, fuller's earth and allied clays market is forecast to exceed 164 million metric tons by 2010, as stated by Global Industry Analysts, Inc. Europe, United States, and Latin America represent the leading clay markets. However, backed by excellent growth from major markets including Australia, India, Indonesia, Korea, Malaysia, Pakistan, Philippines, and Thailand, Asia-Pacific market is forecast to post fastest growth over the coming years.
Bentonite, Fuller's Earth and Allied Clays: A Global Strategic Business Report Major clay product segments analyzed in the report include bentonite, kaolin, fuller's earth and other allied clays. Other clays market comprising ball, structural, fire, white, smectite, specialty, refractory, siliceous, and organophilic clays is the largest, projected to account for nearly 62% of total market by 2010. Kaolin represents the second largest market, with sales estimated to be 35 million metric tons in 2007.
Calcium Carbonate is all set to take over Kaolin's market share. Calcium Carbonate, classified into Ground Calcium Carbonate (GCC) and Precipitated Calcium Carbonate (PCC), is proving to be a tough contender for Kaolin and other traditional products. Paper Industry, which forms the major end use industry for Kaolin, is moving towards Calcium Carbonate due to the latter's high adaptability to alkaline technology and cost effectiveness. Paper Industry is expected to justify the high growth rates for GCC and PCC. Calcium Carbonate, with such high growth potential is likely to sound a death knell for Kaolin and other traditional products such as Titanium dioxide. Several plants manufacturing Kaolin and various other traditional products in North America are on the verge of closure, owing to reduced usage in paper manufacturing and eroding profitability.
Global drilling rig count market is expected to spur growth in bentonite and related clays market. Drilling rig count market is influenced by the amount of fossil fuels exploration, which in turn is fuelled by energy prices. The usage of Bentonite for manufacturing of Foundry Sands and demand for Bentonite for iron ore pelletisation is expected to increase in the near future.
Leading players in the global bentonite, fuller's earth and allied clays market include Amberger Kaolinwerke GmbH, Amcol International Corp., Ashapura Minechem Ltd., BPM Minerals LLC, Black Hills Bentonite, LLC, Caulim Da Amazonia SA, Cimbar Performance Minerals, IMERYS Pigments & Additives Group, Sedlecký Kaolin, S&B Industrial Minerals S.A., Thiele Kaolin Co., TOLSA Group, and Unimin Corp.
Calcium Carbonate – What is it? Natural Wonder In its natural state, calcium carbonate occurs as chalk, limestone and marble. Wet and dry grinding methods are commonly used in processing for industrial uses. To obtain higher levels of brightness and lower abrasion characteristics, calcium carbonate is processed by optical sorting, flotation and/or particle-size classifying.
Industrial Wonder Processed to varying degrees of purity, calcium carbonate exhibits an attractive combination of high whiteness, brightness, low hardness and reactive properties. Paper, plastic, paint, rubber and caulk producers use calcium carbonate as a way to improve quality and lower manufacturing cost. Plate glass, bottle and fiberglass producers use large quantities of calcium carbonate as a source for calcium, an essential ingredient in their manufacturing processes. Used in water treatment systems and stack-gas scrubbing systems for its ability to neutralize acidic manufacturing by-products, calcium carbonate also helps to make many industrial plants more environmentally friendly.
Household Wonder Calcium carbonate is found in everyday products such as bathroom cleaner, shoe polish, and toothpaste. Calcium carbonate is even used as a source of calcium in food.
Processing The processing of calcium carbonate ore is one of size reduction coupled with innovations to improve specific properties. Typically, a stone deposit found underground or in an open quarry is drilled and blasted. The blasted rock is loaded and hauled from the quarry to a processing mill. The rock is crushed, washed and sized. The washing removes fines that can contain a significant portion of the impurities. The processing mill, or plant, further processes the material by either a dry or wet grinding method. Additional processing in the form of optical sorting, flotation and/or particle-size classifying is used to provide an engineered filler suitable for the customer's application.
Mineralogy Calcium carbonate ores can be found in two of the three major types of rocks: sedimentary and metamorphic. Sedimentary rocks, as the name suggests, form from sediment or from transported fragments deposited in water. Limestone, for example, is formed from inorganic remains, such as shells and skeletons. Metamorphic rocks—such as marble, slate, quartzite—form when a rock mass is subjected to great heat and pressure. The principal element in the calcium carbonate ore is calcium (Ca). The ore may contain other elements—Magnesium (Mg), Iron (Fe) and Manganese (Mn)— that affect whiteness, hardness and specific gravity.
