Operational costs, worker safety and CO2 emissions are challenges faced by most mines and quarries today. While there certainly isn’t a silver bullet that would solve all problems overnight, in-pit solutions, such as in-pit crushing and conveying (IPCC) are widely recognized as a good place to start.

(a) open pits are getting deeper requiring lower mining cost solutions, and (b) there is increasing pressure on mining companies to reduce carbon emissions. In-pit crushing and conveying (or IPCC) is a potential solution for both issues. And when we say potential, we mean that it will not work for every case.
