Processes of Ore Formation

Processes of Ore Formation. Current theories of the genesis of ore deposit can be divided into internal (endogene) and external (exogene) or surface processes. It must be understood that more than one mechanism may be responsible for the formation of an ore body.

Process Flowsheets. Hard rock hematite deposits often require a combination of milling, screening and on occasion, fine classification to prepare a finely sized (), liberated feed for beneficiation by gravity separation. This is typically followed by regrinding of the tailings to liberate more hematite for further iron unit recovery by magnetic separation.
