How Metal Powder Is Made: Step 1 of the Powder

The metal ore is crushed and then mixed with another material, usually carbon. Once the mix is complete, it’s put through a furnace to create a reaction that lowers the oxygen and carbon levels in the powder. The reduction in carbon and oxygen leaves the metal mix resembling a less-delicious sponge cake.

Making Metal Powder - MPIF

In solid-state reduction, selected ore is crushed, typically mixed with carbon, and passed through a continuous furnace. In the furnace, a reaction takes place, reducing the carbon and oxygen from the powder, that leaves a cake of sponge metal which is then crushed, separated from all non-metallic material, and sieved to produce powder.
