Big Gossan Mine is an open stope mine with delayed paste fill method owned by Freeport McMoRan Mining Company. In order to support its production expansion, underground mine division has decided to build a paste plant to produce paste, which can be used to refill voids after mining completed. As you can see in this picture, the plant was build in underground, on top of the mine orebody. The disc filter level is a level for tailing processing to provide appropriate solid density to be added into the mixing system.
Big Gossan Paste Plant Project is about 95% completed. The plant is scheduled to run its full production on June 2011.
