A method is described of producing steam from geothermal brine comprising dissolved toxic elements without significant precipitation of toxic solids, the method comprising: removing geothermal brine comprising water, non-condensable gases and toxic elements from an extraction well drilled into an underground aquifer; removing non-condensable gases from the geothermal brine to produce non-condensable gas-free brine and maintaining the non-condensable gases separate from the non-condensable gas-free brine to prevent reaction therebetween with dissolved solids in the non-condensable gas-free brine; flashing the non-condensable gas-free brine to produce steam and flashed brine; and introducing the flashed brine into an air-free handling system to prevent contact of air with the flashed brine.
