laterite iron ore process

Laterite Ore - an overview | ScienceDirect Topics

Laterite Ore. Laterite ores are formed by the process of weathering and normally found in tropical regions where weathering extracts and deposits it in layers at varying depths below the ground surface.

Direct extraction of nickel and iron from laterite ores ...

Introduction. Over the past 30 years laterite ores have become increasingly more important as a source of nickel metal (Dalvi et al., 2004).Several methods of nickel extraction from laterite ores have been piloted and some were put into full operation, including acid leach with sulphuric, nitric and hydrochloric acids, ammonia leach and the pyrometallurgical process (Superiadi, 2007).
