A geothermally powered zinc production subsystem includes a geothermal system with a wellbore extending from a surface into an underground magma reservoir. A hopper receives a sphalerite ore that is crushed and provided to a flotation tank. The flotation tank is heated by a heat transfer fluid heated by the geothermal system, and a product of the flotation tank is used to prepare zinc.
