Turning Coal into Carbon Fiber - Industry TodayTraduire cette page

Researchers and industry partners will be converting the coal tar, which is a byproduct from coke production for the steel industry, into mesophase pitch — a liquid crystal — which can then be spun and thermally converted to carbon fiber. If successful, this new carbon fiber product could increase the value of coal tar pitch by five to 55 times of its current value, and find applications ...

The damage associated with a ton of SO 2 varies from $1,800 to $10,700 (5th and 95th percentile) at coal plants and from $1,800 to $44,000 at natural gas plants (2007 USD). The differences reflect the fact that most coal-fired power plants are located farther away from population centers than natural gas plants are located from population centers.

What are the main methods of mining? | .

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
