When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
More
The enriched ore is heated to remove sulphur, leaving a material called calcine. The calcine is smelted, removing more impurities and leaving a matte of liquid copper and iron sulphide. Air is blown into the matte, forming a material called

2023年2月17日 The trend of declining copper head grades is well established and unlikely to be reversed. Similarly, oxide ore bodies, which do not require concentrators and can be processed through less capital-intensive routes, are being exhausted. The mining industry has responded to these challenges by processing ever-increasing volumes of sulfide ores.
