Description:   A chemical-free gravity circuit was proposed by Crowne Butte Mines for their New World mine development, Cooke City, Montana to eliminate the use of cyanide in gold processing.  The process utilizes only gravity and froth flotation, with the ore first being ground and then passed through a centrifugal separator-flotation stage.  The process was proposed, along with the elimination of two open-pit mines, to alleviate environmental concerns and facilitate the permitting process.
