Report summary

Until the recent development of the Bottom Blown Furnace (BBF) in China, there had been no major developments in copper smelting technologies since the 1990s. It is Wood Mackenzie's view that BBF technology will continue to extend its footprint across the globe and will eventually be the technology of choice for an increasing number of greenfield projects.
