Ultrafine ore concentrate with a high amount of stored energy can be produced by mechanical milling, and can be deoxidated fast below 700℃ by either the coal-based or gas-based process. This novel process has some advantages over others: high productivity, low energy consumntion, and environmental friendliness.展开更多
