Scope of Work
 

GR Engineering was engaged by Wolf Minerals for the engineering, procurement and construction (EPC) of a 3 Mtpa tungsten and tin processing plant and associated infrastructure.  When operating, the project produced around 21 tonnes of 65% grade WO3 and 7 tonnes of 25% tin concentrate per operating day. The process involved primary, secondary and tertiary crushing, dense media separation to upgrade sand and gravel sized material and spirals and tables to concentrate fines material.  Magnetic separation was then used to separate and upgrade the tungsten and tin concentrates which were dried and packaged for container transport. GR Engineering was also responsible for much of the site infrastructure including a 70 Ml water reservoir, river pumping system, site offices, metallurgical laboratory and site drainage and drainage control systems.
