ABSTRACT:
Chromium or other metal carbides are recovered from chromates or equivalent soluble metal salts in substantially pure form by solid state carburization. The chromates may be derived from low grade ore to provide an overall non-smelting procedure which is non-polluting. The carbide may be formed into sponge metal.
