Optimization of the grind size could lead to the maximum liberation of the copper, therefore increased productivity and high quality concentrate would be produced. According to Williams [3], productivity is the measure of the extent to which the resources of an organization are being used effectively in transforming inputs into useful outputs.

The tested granular material was copper ore of particle size 0–2 mm and relative moisture content of 0.5–11%. Both vision and thermovision images were taken at standard and macro scales. The results suggest that median-intensity vision images monotonically reflect copper ore moisture in the range of about 0.5–5%.

An ore vein is a rare underground terrain feature that provides massive amounts of ore. Ore veins occur as large branching networks of rock with high concentrations of associated ore. Copper veins are largely made of granite associated with copper ore and raw copper. Iron veins are tuff associated with iron ore and raw iron. Ore veins can snake and branch and eventually dead …
