Mining Mill Performance Test
  • Inside a mining company’s AI transformation | McKinsey

    The mood was apprehensive as data scientists, metallurgists, and engineers from Freeport-McMoRan filed into the control room of a copper-ore concentrating mill in Bagdad, Arizona, on the morning of October 19, 2018. They had come to learn what would happen when they cranked the big mill up to a work rate that had never been tried. The possibility of causing problems at the mill weighed on
