Abstract: Methods and systems for producing are disclosed. A method for producing iron, for example, comprises: providing an iron-containing ore to a dissolution subsystem comprising a first electrochemical cell; wherein the first anolyte has a different composition than the first catholyte; dissolving at least a portion of the iron-containing ore using an acid to form an acidic iron-salt solution having dissolved first Fe3+ ions; providing at least a portion of the acidic iron-salt solution to the first cathodic chamber; first electrochemically reducing said first Fe3+ ions in the first catholyte to form Fe2+ ions; transferring the formed Fe2+ ions from the dissolution subsystem to an iron-plating subsystem having a second electrochemical cell; second electrochemically reducing a first portion of the transferred formed Fe2+ ions to Fe metal at a second cathode of the second electrochemical cell; and removing the Fe metal.

Abstract: A method for opening an on-line brokerage account includes the steps of opening an on-line brokerage account for a user based on account information received from the user, the on-line brokerage account having one or more restrictions, generating an application based on the account information: requesting that the user submit required information with the application within a predetermined time to remove the one or more restrictions from the on-line brokerage account, and removing said one or more restrictions from the on-line brokerage account when the application including the required information is received within the predetermined time.
