Carbon black shortages slow down mining
www.energybulletin.net April 27, 2006 archives
Mining companies are complaining about a shortfall in the supply (not enough supply) of the giant tires that go on large dump trucks and other heavy equipment (very large machines). These out size tires stand as tall as 12 feet / 4 meters tall and can spread 4 feet / 1.3 meters wide. They are used everywhere from the Canadian tar sands to open-air coal mines (strip-mines) in the United States and China, but lately (recently) they have become almost as precious (valuable) as gold and silver. Prices have quadrupled (4X) for some of them in the last year to more than $40,000 a tire.
Tire companies complain they are also squeezed (effected negatively) by rising prices for raw materials, with natural rubber prices rising nearly six fold (6X), to about $2 a pound since 2002. High crude oil and natural gas prices are also adding a burden (problem) to tire companies, which use petroleum in large amounts to produce the carbon black needed for tire carcasses (outside of the tire) and threads (ropes in the tire).
