  "term": "Hardhead",
  "field": "Industrial and trades",
  "definition": "A brittle, iron-rich intermediate product formed during the smelting of tin ores. This metallic mass consists mainly of an iron-tin alloy with impurities like arsenic and sulfur, and it settles at the bottom of the furnace due to its high density. Hardhead must be separated and re-treated to recover the entrained tin, a process that adds cost and complexity to the smelting operation.",
