decrease of mining cost. The stripping phase plays an important role in the overall mining system, in particular in matter of cost (up to 40% of the global cost of mining). Moreover, not less than 85 million m3 (111.2 million yd3) of waste rocks are moved on average annually from the different pits. Blasting alone takes 8% of stripping expenditures.
The implementation of a Cast Blasting method will contribute to achieve these goals. Moreover, it will help dealing with the consequences of an unstable phosphate market. The transformation of capital expenditures into operational expenditures is very important to reduce cost and Cast Blasting can help to achieve this.
