Diamond Mining Gets New Technology.

Diamond Mining and the retrieval of rough diamonds from tons of rock has now become ultra efficient with the intrduction of a a new optical sorting method that identifies the diamond rough in the midst of the extracted kimberlite bedrock and separates them out at lightning speed.

A high-resolution linescan camera, which – unlike a conventional camera – produces a continuous image rather than sequences of images. The camera faces the fragments of broken rock, which are thrown from a conveyor belt into an intercepting pit. The stones are illuminated from a certain angle as they fall. If the beams encounter a diamond, the light is deflected towards the camera. This registers the flashes of light and transmits a signal showing their exact position to a computer. The computer, in turn, is connected with 200 air jets with valves that can be separately opened and closed.


With existing diamond mines aging and yields decreasing, the introduction of this new technology will increase the yield and lower costs of mining and exploration.

I like what you guys are up too. Such clever work and reporting! Keep up the superb works guys I have incorporated you guys to my blogroll. I think it'll improve the value of my site :)

Wonderful Web site! I wished to ask if I might be capable of site some of your net page and use a couple of factors for a term paper. Please drop me an e mail if its ok or not. Thanks

Hello there. This is a wonderful post. I'm going to e-mail this to my peoples. I stubble upon this blog post while surfing on internet. I'll be sure to come back. thank you for publishing.

Sorry for the huge review, but I'm really loving the new Zune, and hope this, as well as the excellent reviews some other people have written, will help you decide if it's the right choice for you.

Apple now has Rhapsody as an app, which is a great start, but it is currently hampered by the inability to store locally on your iPod, and has a dismal 64kbps bit rate. If this changes, then it will somewhat negate this advantage for the Zune, but the 10 songs per month will still be a big plus in Zune Pass' favor.

I learned about your blog on Facebook just now and really love it.. i bookmarked it and will be back to check it out some more later
