President and chief executive Tim Shuttleworth will present Profitability Clearing the Chinese ‘Green Fence’ at the event in Germany. It will focus on Eriez’ technology to increase purity levels while maintaining total metals recovery.

“Chinese import regulations were boosted with the so-called ‘Green Fence’ initiative in 2013 wherein the Chinese set an upper limit of two percent waste in the metal commodities being imported. Without the right process, this level of purity can lead to lowered total recovery and loss of valuable metals,” said Mr Shuttleworth.
 
“Eriez decided to apply a well-known processing technique from the world of mineral processing to increase the high purity level off the eddy current separator while maintaining or increasing total metal recovery. We concluded that 98 percent purity (grade) was achievable with high recovery of total available aluminium.”
 
Mr Shuttleworth will describe how the mineral processing technique utilizes recirculating streams so the occasional misplacement of metal into the waste stream, or waste into a metal concentration stream, is self-corrected.
 
He will also show illustrations explaining why particles occasionally misplace and go over Eriez’ test results and data to support this technology.
 
The event will be held March 25-27 in Berlin, Germany.
