This report proffers a thorough economics of the production of diamonds via opencast mining. The process involves mining tuff rocks such as kimberlite rock, extracting the ore from them using hydraulic shovels and dumpers, then drilling to make holes in the rock benches and placing explosives containing a mixture of water and ammonium nitrate slurry. The explosives are blasted in a controlled pattern. After mining, the rocks are subjected to natural weathering. The weathered rocks are then crushed, which is proceeded by sending the crushed rock in a separation system where the diamonds are separated from other minerals using a ferrosilicon liquid, thus giving diamonds at the bottom of the separation tank.
