Laboratory investigations of the physical parameters influencing the in situ leaching of tungsten

Tungsten leaching potential from geothermal reservoirs was investigated using a flow-through reactor with the characteristic physical properties of reservoir. minerals were tested at 200 °C, 250 °C and 300 0.5 1.0 mL/min flow rates to determine most favourable conditions for mobilisation tungsten. In situ yielded tungsten concentrations 1–182 mg/L in leachates, pure scheelite being effective mobilising The highest concentrations, which obtained generally observed first 30–60 min because rapid fluid–rock interactions
