Chromite- Dinagat ccil

Based on float, chromite occurs in the form of massive, disseminated and banded localized in the serpentinized dunitic country rock intercalated with the harzburgite. According to previous workers who made a detailed investigation of the mining area, the massive chromite occur as lenses or pod-shaped ore body ranging in thickness from 0.5 to 1.0 meter.

(Bio)leaching Behavior of Chromite Tailings

In rocks, chromite grains are locked either within the iron ore minerals (goethite/hematite) and silicates or the chromite with inclusions of silicate . Silicates are more susceptible to weathering than chromite, which represents a source of chromite nanoparticles (containing mainly Cr(III)), that after dissolution, could be oxidized to Cr(VI) [ 10, 11 ].
