Understanding the effects of goethitic iron ore – Process ...

Goethite present in iron ore deposits affects how your mine manages the handling and processing of ore. Failing to understand how the different textural composition of goethite impacts processing performance can lead to downtime and reduced mine efficiency. Textural classification allows mines to better predict where different types of goethite are present, allowing blending processes to be adjusted to address
