Processing/workflow

The ore extracted from Pöhla-Globenstein will be processed in the Mittweida plant, including the following processing phases:  

• Crushing (< 200 mm)
• Cleaning, sludge removing
• Presorting (classification in 3 steps)
• Optosensoric measurement technology for identification (fluorescence in scheelite)
• Sorting with the help of X-rays (developed by the Pyral AG in Freiberg/Germany)
• Gravimetric separation via spiral separators
• flotation of scheelite cassiterite
• Multi-stage dewatering of the products
• Drying of the tungsten concentrate by means of new

Target of the pilot processing plant

• Simulation of the future preparation process
• Basis for the design of the large processing plant for the regular operation of the mine.
• Basis of the Bankable Feasibility Study.
