History

A concise historical narrative of NAICS Code 331492-04 covering global milestones and recent developments within the United States.

  • The Secondary Smelting & Refining-Nonferrous (Manufacturing) industry has a long history dating back to ancient times. The first known use of nonferrous metals was by the ancient Egyptians, who used copper to make tools and weapons. The Greeks and Romans also used nonferrous metals extensively, with the Romans being particularly skilled in the art of smelting. In the United States, the industry began to take shape in the late 19th century, with the discovery of large deposits of lead, zinc, and other nonferrous metals. The industry grew rapidly during the early 20th century, with the development of new technologies and the increasing demand for nonferrous metals in various industries. Notable advancements in the industry include the development of the Hall-Heroult process for aluminum smelting and the use of electrolysis for refining copper. In recent history, the industry has faced various challenges, including fluctuations in metal prices, increased competition from foreign producers, and environmental concerns. However, the industry has also seen significant growth and innovation, with the development of new technologies for recycling and refining nonferrous metals. For example, the use of hydrometallurgical processes has allowed for the recovery of metals from low-grade ores and waste materials. Additionally, the industry has become more focused on sustainability and environmental responsibility, with many companies implementing green initiatives and reducing their carbon footprint.
