The Rocks That Burn: Is Oil Shale the Answer?—Part I
February 2006 by Bill Rich
The day is old in the Rangely Oil Field in northwestern Colorado. I’ve paused in my southbound trip to take a gander at this historic field, one of the largest in the state. Intricate pipelines funnel water and carbon dioxide to the source rock far below.

Selecting a Gold Recovery System
March 2001
Tabling and jigging are two relatively inexpensive methods of recovering the “free particle values” from the noble metal ores. However, not all ores contain their values as free particles. In fact, many gold ores contain appreciable amounts of “metallic gold salts,” some of which readily dissolve in the system water and continue to migrate right along with it.

Continental Drift
November 2003
As soon as reasonably accurate maps were made, 200 years ago, one could not help but note the parallelism of some coastlines with those on other continents. The coastlines of Africa and South America, in particular, are strikingly similar. The first scientist to write on the subject was an Austrian, Edward Suess, who put India, Africa, and South America into a supercontinent he named “Gondwanaland.” But, it was not until Alfred Wegener, a German, came out with his “Theory of Continental Drift” in 1912, that scientists took note.
