Metso‘s Frederic Barou, Bid Manager, Mining Systems and Jorma Kempas, Bid Manager, Lokotrack are interviewed by Paul Moore from International Mining.
Different applications for our IPCC solutions (In-Pit Crushing & Conveying) are discussed, such as at Severstal Olkon’s operations in Russia, as well as our role as a driver of sustainability in mining.
Primary crushing is often synonymous with a parade of loud dump trucks driving around, generating dust, noise and consuming excessive amounts of fuel. In a conventional crushing plant, a drill and blast team blasts the shot and develops a muck pile. A front end loader at the muck pile loads dump trucks, which transport the rock to a fixed primary crusher. This translates to a large number of trucks and people moving between the blast site and the fixed crushing plant, generating unnecessary CO2 and dust emissions as well as exposing the workers to injuries caused by the traffic.

In order to make the right decision, it is necessary to compare the total cumulative cost – including both capex and opex expenditure – between the conventional truck haulage system and an in-the-pit (ITPS) solution. In some cases, the capital expendititure of the conventional haulage system may be initially lower, but the lower operation cost of the ITPS system will compensate the difference over the years to come. The key decision criteria are the length of the break-even period and the cumulative monetary savings at the end of the observation period.
In the long run, in-the-pit crushing is the ideal solution. Depending on the conditions, an in-pit crushing solution can achieve full or partial replacement of trucks for material transport in and out of a mine. The result is a more efficient production with both economic and environmental benefits.
Instead of feeding a dump truck, an excavator located on the muck pile loads material directly into the hopper of a Lokotrack® mobile crushing plant. Crushed rock is then transported to an in-pit belt conveyor via mobile Lokolink conveyors. The conveyor carries crushed rock from the Lokotrack to the fixed secondary plant for further processing – no dump trucks are needed.
When blasting is performed, the Lokotrack and Lokolink conveyors move to a safe distance. After the blast, a wheel loader cleans the quarry floor and the Lokotrack plant moves to the new muck pile. Operation resumes with minimal production downtime.
