This document discusses the need for lean iron ore beneficiation in India to utilize low-grade iron ore deposits. It notes that India has large reserves of iron ore but current mining practices only utilize ore above 58% Fe. Beneficiating low-grade ore deposits through finer grinding and pelletization could increase reserves and improve economics.

Chrome wash and beneficiation plants are essential to the production of high-quality chrome ore, with various technologies available to suit different types of ore and operational requirements. In South Africa, these plants play a critical role in the country's chrome mining industry, contributing to the global supply of this valuable mineral.

It is important to test lean chrome ore and investigate its behavior alone and when blended with other chrome ores. Many phases can form during reduction, governing final product composition.
