摘要: An electrolytic cell for recovery of metal from mineral ores or concentrates comprising a tank for holding a slurry of electrolyte and the mineral ore or concentrates. Vertical anodes are radially disposed in the tank and vertical cathodes enclosed in diaphragm bags are interposed between the anodes. Agitating means are located in the tank below the anodes and cathodes. Metal is removed from a central collecting container in the tank by pump means.

摘要: Lead is selectively recovered electrolytically from a mixture of metal sulphides in an aqueous chloride electrolyte by controlling the rate of agitation and oxidation conditions so that metal sulphides other than lead remain substantially undissolved.

摘要: A programming mechanism is disclosed for controlling the application of power to apparatus performing successive steps in a process. The mechanism includes an electronic timer for controlling the time period of each step. The timer includes an R-C timing circuit, the R-C constant of which may be adjusted to any suitable value for each different step of the process by connecting into the circuit a different R-C circuit element, such as a variable resistor for each step in the process that the circuit controls. For this purpose, a multisection, multiposition stepping switch is connected to the R-C timing circuit and a different variable resistor is connected to one or more of the terminals of the stepping switch so that as the switch is stepped to the next position a different R-C timing constant may be provided to control the time period of the electronic timer.

摘要: Recovering zinc from zinc bearing ore or concentrate (1) in an electrolic cell (3) which includes a cathode (5) containing cathode compartment (16) and an anode (4) containing anode compartment (2). The cathode and anode compartments are defined by interposing between such compartments an ion-selective membrane (6) capable of preventing migration of ionic copper from anode compartment (2) to cathode compartment (16). Process includes forming in anode compartment (2) a slurry of ore or concentrate (1) with a chloride and copper-ion containing solution, intimately mixing oxygen bearing gas (7) with the slurry, maintaining the mixture substantially at atmospheric pressure and at a temperature up to the boiling point of the solution, and maintaining the pH of the mixture from 1 to 4. The resultant solution is rich in solubilized zinc. At least a portion of the mixture is withdrawn and resultant solution (12) separated therefrom. Zinc bearing ore or concentrate (1) is contacted with solution (12) precipitating ionic copper therefrom. Resultant solution (15) is introduced to the cathode compartment (16) and zinc electrochemically recovered at the cathode (5).
