IN-PIT CRUSHING JUNE 2019 • E&MJ 73 other mines that have paved the way for IPCC in the last two decades: Chuquicamata and Escondida have both been front runners in the development of semi-mobile IPCC, as well as the EGAT-mines of Mae Moh in Thailand, to name only a few." FLSmidth currently has eight IPCC projects under execu- tion globally, including several new installations coming up in India and China. Jabs added, "Also, we are currently executing the next semi-mobile [IPCC] expansion in a Brazilian iron-ore mine." RWE is also working on S11D. The company was contract- ed in 2013 to provide expert consultancy services for the mine, which include: help with mine planning, implementa- tion and support for the mining systems, and training. The RWE team has played host to many Vale employees since June 2016, conducting training for the group at one of its truckless thermal coal mines in Germany as well as an opera- tion in Hungary. Heiertz explained, "We would like to highlight these Ger- man lignite mines: the mines are 100% continuous mining operations. Also, when they are not crushing the waste rock, the operational mode of the large bucket-wheel excavators is very similar to the operation of fully-mobile crushing units. In these mine operations, RWE is training international mining operators in IPCC technologies and planning capacity." He continued, "The S11D operation in Brazil is one of the flagship projects globally for large-scale, fully-mobile IPCC operations, which are running very successfully. Several mine operators in Chile, such as Los Pelambres from Antofagasta Minerals, are using semi-mobile IPCC in their operations very successfully, and in many quarry operations worldwide small, fully-mobile IPCC units are also used very efficiently." In addition to its work at S11D, RWE is currently involved in the development of IPCC-based and continuous mining systems for operations in South America, Australia, China, Southeast Asia and Scandinavia. thyssenkrupp meanwhile pointed to the YiminHe coal mine in Inner Mongolia, as a successful example of IPCC technology. "This mine is equipped with both semi-mobile and mobile crushing plants from thyssenkrupp," explained Paulo Costa, head of OU mining systems at thyssenkrupp Industrial Solu- tions. "The operation utilizes a highly efficient bench oper- ation with a mobile crusher on the one hand. On the other hand, where operational flexibility is required, a semi-mobile crushing plant is installed. With this combination, the op- erator achieves the benefits of conveying by still having the flexibility of trucking, where needed. "Additionally, a barracuda compact bucket-wheel excava- tor system will soon be in operation to strip overburden. After being extracted by the barracuda, the material is taken by the belt wagon to the conveyor system, which transfers the overburden to the dumping site." thyssenkrupp is currently commissioning another IPCC sys- tem at PhosAgro's Apatit mine in Russia. This consists of a semi-mobile crushing plant, and a set of three conveyors con- necting the mine with the external dump area and a spreader. "In this mine, the switch from truck and shovel to IPCC leads to tremendous savings of operational costs, increased safety in operations as well as reduced CO 2 emissions," Costa added. The Alimak elevator is the perfect solution for both underground and surface mining applications, such as pelletising plants, smelters, concentrators, and other ore processing plants. Alimak elevators have been delivered to a variety of mine applications around the world since 1957. No environment is too hostile for the latest Alimak elevator range. • Built to perform in the world's harshest environments • Improved operational efficiency, superior HSE performance and reduced maintenance costs • Unparalleled track record in reliability, safety & durability Contact us at for further information.
