Disclosed is a method of reducing a metal-oxygen compound wherein carbon acts as a reducing agent. The method includes in a first reaction stage, passing CO gas into a reaction chamber containing the metal-oxygen compound, under conditions such that CO is converted to solid carbon and carbon dioxide thereby introducing the solid carbon so formed to said metal-oxygen compound, and in a second reaction stage, causing the carbon, introduced to the metal-oxygen compound in the first reaction stage, to reduce the metal-oxygen compound. There is present, at least in the second reaction stage, a first promoter material effective to promote the reduction of the metal-oxygen compound. The first promoter material includes a first promoter metal and/or a compound of a first promoter metal. Also disclosed is an apparatus for carrying out the reduction of a metal-oxygen compound wherein carbon acts as a reducing agent.

Method and apparatus for reducing metal-oxygen compounds

The invention relates to a process for forming a laminate comprising a core of a compressed metal powder mixed with a foaming agent between two metal layers, comprising the successive steps of providing two metal strips and a stock of powder comprising a metal powder mixed with a foaming agent; applying a layer of the powder between the two metal strips; feeding the metal strips, with the powder between them, to a rolling mill; rolling the two strips with the powder between them to form a laminate of compressed powder between two metal layers. The invention also relates to an associated device and to the product formed using the process.
