Abstract The depletion of highgrade ores has forced the utilization of lowgrade ores. The small liberation sizes in the lowgrade ores require fine grinding which is an energy intensive operation. In the present study, lowgrade chromite ore bearing platinum group of elements (PGE) was used as an experimental material. The previous study concluded the liberation size of around 150 µm for ...

A 5litre vertical batch stirred ball mill was used to study comminution characteristics. Chromite sand was used as the feed. A factorial design was prepared with the following parameters, which influence grinding in a stirred ball mill: pulp density, pintip velocity, ball density, and size. The energy required for grinding the chromite sand ...

The concept was to treat the finer silicate rich fraction in the IsaMill and the coarser chromite rich fraction through the ball mill. This circuit is typical of a UG2 plant in which maximum silicate with minimal chromite breakage is targeted. As a result of the circuit change an opportunity for optimisation around the industrial scale ball ...
