  • Iron Ore production in the Pilbara Rio Tinto

    Activities involved in finding, mining and processing iron ore at our Pilbara operations have been simplified in the following diagram Rio Tinto operates 11 iron ore mines in the Pilbara and the specific sequence of activities varies from mine to mine Excellence in planning, scheduling and quality control are fundamental to the process Iron Ore production in the Pilbara Resource14/3/2018· When the iron ore is extracted from the 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 This stepThe Six Main Steps of Iron Ore Processing MultotecIron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines Manual mining method is normally limited to float ores and small mines Mining of reef ore is also being done manually on a small scale The float ore area is dug up manually with picks, crow bars,Iron Ore Mining | Techniques | Metal Extraction
