Abstract

This invention relates generally to a process for producing enhanced manganese-zinc geothermal filter cake compositions. After precipitation of zinc and manganese from a geothermal brine, the process repulps and washes a mixed polymetallic oxide/hydroxide/oxychloride geothermal filter cake with a repulp and/or a wash liquor to produce an enhanced, slurried manganese-zinc geothermal filter cake composition. The process can further include dewatering the slurried manganese-zinc geothermal filter cake composition to produce an enhanced, dewatered manganese-zinc geothermal filter cake composition, and the process can further include drying the dewatered manganese-zinc geothermal filter cake composition to produce an enhanced, dried manganese-zinc geothermal filter cake composition. The enhanced manganese-zinc geothermal filter cake compositions have enhanced concentrations of zinc and manganese and reduced concentrations of chloride and other salts. The enhanced manganese-zinc geothermal filter cake compositions can be processed to extract manganese and zinc therefrom.
