In 2001 a new magnetic separation unit was built for processing raw magnesite. It uses high intensity rare earth roll separators in order to upgrade the grade of the kiln feed material. Prior to magnetic separation the raw material is dried using the enthalpy of the kiln flue gases. 

In February 2004 the erection of an 8.000 tpa production line was completed for the manufacture of electrical grade magnesia powders destined for use in low temperature heating elements, using DBM as  the main raw material. The line was a result of an agreement between UCM Group (now IMERYS Fused Minerals Hull) for the transfer of part of EGM production from Hull to Yerakini.

In December 2004, Grecian Magnesite's Turkish subsidiary Akdeniz acquired certain assets (calcination, beneficiation facilities and mining concessions from Comag Continental).

Starting from 2006 modern and very efficient bag filters were installed at the kilns in order to supplement the existing electrostatic filters. Dust emissions are thus reduced to very low levels far bellow legal levels. Also, the partial use of biomass-fuel in all kilns was introduced successfully with significant techno-economical and environmental advantages.

In 2007 Grecian Magnesite acquired 50% of the Holland based industrial minerals processor and trader Van Mannekus & Co B.V. 

In 2008 the use of color camera sorters was extended for the qualitative separation of magnesite grades. Two more sorters are added in a new versatile installation. 

Starting in 2006 and completed in 2010, a new secondary mineral processing line was put in operation. The new line processes fine material -18mm , which was not possible to treat with the existing laser based photometric ore sorters. The flow sheet developed by GM engineers includes patented screens, special magnetic separators and new generation optical sorters with color digital cameras. With the new installation it is possible to process both the current production fine material as well as previously stockpiled fine ROM material. This results in lower overall production costs and extends the life span of the mine. 

In 2012 Grecian Magnesite acquired and set in operation a new mobile screening unit, which is used to screen the old stockpiled fine RoM material at the mine site. The mobile unit removes the -4mm fraction. The +4mm fraction is being transported to GM’s stationary processing installations. The on-site screening of the fine stockpiles results in lower transportation costs and a substantial increase in the yield and productivity of the downstream beneficiation process.
