The announcement on the 15th Nov 2012 stated some of the problems with the current filter.

"The plant is designed to process 12t per hour and in the past this has been extrapolated to a design capacity of 1200t per week based on 100 hours of running per week. It has been confirmed in the review process, that 12t per hour is indeed achievable but continuous running at these levels, as has been done a number of times since August, results in bottlenecks that stop the process. Specifically the inability to handle the fines produced in such larger quantities cause the clarifier, filters and dryer to overload. This fines material forms the large part of the NMP by-product. At these throughput rates fines have to be stockpiled and dried and reprocessed, which is both inefficient and costly. As a result of this the plant has been run at 6t per hour to reduce these problems."

Seems clear to me that the new filter will improve the process, improve efficiency, reduce cost, etc. We probably won't see the reported financial gain of the new filter for a few months though?

Butchy.
