Patent number: 8382880Abstract: A process for digesting molybdenum oxide concentrates includes suspending a molybdenum-containing starting material in an aqueous solution so as to obtain a suspension. While stirring, an oxidizing agent and an alkali solution of at least one alkali metal are metered to the suspension so as to set a pH and produce a product having a molybdenum content of at least 98% of the molybdenum-containing starting material. The alkali metal is selected from the group consisting of Na, K and Li.Type: GrantFiled: November 4, 2008Date of Patent: February 26, 2013Assignee: H. C. Starck GmbHInventors: Josef Schmoll, Brigitte Schimrosczyk, Gisbert Ebeling, Joerg Henze

Patent number: 7048843Abstract: The invention relates to a method for producing metal hydroxides or alkaline metal carbonates by anode dissolution of the corresponding metals and precipitation of the hydroxides or alkaline carbonates in an aqueous medium. The anode dissolution of the metal components is carried out in the anode compartment of a three-compartment electrolytic cell. An aqueous auxiliary salt solution is fed to an intermediate compartment that is disposed between the anode compartment and the cathode compartment and that is separated therefrom by a porous membrane. An at least not alkaline metal salt solution is continuously taken from the anode compartment while an alkaline auxiliary salt solution is continuously taken from the cathode compartment. The at least not alkaline metal salt solution and the alkaline auxiliary salt solution are combined outside the electrolytic cell for the purpose of precipitating metal hydroxides or alkaline metal carbonates.Type: GrantFiled: June 6, 2001Date of Patent: May 23, 2006Assignee: H.C.

Patent number: 6875416Abstract: The invention relates to a method for producing lithium-transition metal mixtures of general formula Lix(M1yM21-y)nOnz, wherein M1 represents nickel, cobalt or manganese, M2 represents chromium, cobalt, iron, manganese, molybdenum or aluminium, and is different from M1, n is 2 if M1 represents manganese and is 1 otherwise, x is comprised between 0.9 and 1.2, y is comprised between 0.5 and 1.0 and z is comprised between 1.9 and 2.1. According to the inventive method, an intimate mixture composed of transition metal compounds containing oxygen and of a lithium compound containing oxygen is calcinated, said mixture being obtained by processing a solid powder transition metal compound with a solution of said lithium compound, and then drying. At least the M1 compound is used in powder form having a specific surface of at least 20 m2/g (BET) and calcination is carried out in a fluidised bed.Type: GrantFiled: August 13, 1998Date of Patent: April 5, 2005Assignee: H.
