Which code does this activity belong in?
Establishments in this industry process minerals beyond basic beneficiation through methods such as calcining or dead burning. The key distinction from Cut Stone and Stone Product Manufacturing is that this code covers chemical or thermal transformation of raw minerals, whereas cutting and shaping of finished stone products belongs in Cut Stone and Stone Product Manufacturing. Ground or Treated Mineral and Earth Manufacturing also differs from Mineral Wool Manufacturing, which uses siliceous materials to manufacture insulation products rather than process minerals for other applications.
