    Abstract: An autoclave for pressure oxidation of a slurried material including at least one sulfide material, and a method. The autoclave includes a pressure vessel for receiving the slurried material. The pressure vessel includes compartments being arranged horizontally one after the another and separated by dividers. Each divider is provided with an upper edge or at least one opening that defines level of the slurried material in the compartment. An inlet is arranged for feeding oxygen-containing gas into the pressure vessel. An agitator arrangement is arranged for agitating the slurried material in at least one of the compartments, the agitator arrangement including at least an upper impeller and a lower impeller, the impellers arranged along a vertically aligned shaft. The upper impeller is arranged at a height above the mid-level of one of the compartments, and the upper impeller is an upward pumping axial or mixed flow impeller.

    Abstract: Provided is a method of inhibiting degradation of an extractant by an anhydrous environment avoiding and metal stripping, the method including the steps of: (a) stopping the addition of soda ash (Na2CO3) to an extracting reaction tank; (b) starting solution recirculation and stopping solvent recirculation of a settler; (c) supplying a solvent from a loaded organic tank to a scrubbing reaction tank, in which the scrubbing reaction tank, stripping reaction tank and extracting reaction tank are connected for circulation and operating stirrers of the scrubbing reaction tank, stripping reaction tank and extracting reaction tank; (d) supplying a sulfuric acid solution having a controlled concentration with a diluting solution to the stripping reaction tank; (e) transferring the solvents of the settler, the loaded organic tank and all the pipes to the scrubbing reaction tank; and (f) stopping the step (e) and initiating solvent recirculation.

    Abstract: This invention relates to treated geothermal brine compositions containing reduced concentrations of iron, silica, and manganese compared to the untreated brines. Exemplary compositions contain a concentration of manganese less than 10 mg/kg, a concentration of silica ranging from less than 10 mg/kg, and a concentration of iron less than 10 mg/kg, and the treated geothermal brine is derived from a Salton Sea geothermal reservoir.
