With the rapid increase of fuel prices in the last two years, there has recently been reconsideration of the application of crushing and conveying in open pit mines. This presentation examines their potential role in hard rock base metal and gold mines.
Since the early sixties, there has been optimism that trucks in large open pit mines would be replaced by belt conveying systems, resulting in improvements in terms of economics and, more recently, carbon emissions. In the last five years, these developments have become more interesting due to the highest oil price in history, and this has led manufacturers to design a number of alternative systems. Consequently, there has been a “new focus on IPCC (in-pit crushing and conveying) systems” and
this is one of the focal areas of this congress.
Despite this increased interest, in-pit crushing has had limited or no success in deep, hard rock open pit mines, and trucks have continued to find application as they get larger and pits deeper. While ore crushing has been used in specific conditions, few mines have successfully and economically implemented waste crushing.
