:: Blasting: Effective Fragmentation


Processing ore to extract minerals is a highly inefficient process, and one which uses the largest proportion of electrical energy on a mining site. Chunks of rock are milled to smaller sizes to allow the precious metals to be extracted from the ore. Research and alternative systems design has been conducted to demonstrate ways in which precious metals may be separated from the ore body more efficiently; including ore classification, gangue rejection and additional crushing prior to grinding. But the simplest way to reduce the milling time is to ensure the particles are pre-treated before milling i.e. have undergone a blasting process resulting in more effective particle serration or fragmentation. The economic and environmental impact of this pre-milling process is substantial: it has the potential to increase production while reducing operating costs. This is good news for investors.
