Tungsten extraction and processing Metalpedia Asian Metal. Tungsten scrap is a very valuable raw material due to its high tungsten content in comparison to ore. Contaminated cemented carbide scrap, turnings, grindings and powder scrap are oxidized and chemically processed to APT in a way similar to that used for the processing of tungsten ores.
