The geological and hydrogeological domain of the open pit mine site is the main source for slope stability investigations. Madenkoy copper mine accounts for nearly 12% of the overall Turkish copper resource; the mine's average copper content is 3%. This mine had previously used the under-ground mining method; however, after 2014, the operation

This paper investigates the long-term production scheduling and the crusher relocation plan of open-pit mines using a semi-mobile IPCC system and high-angle conveyor. A series of candidate high-angle conveyor locations is generated around the pit limit, with a crusher located along each conveyor line.

About 3.5km of the conveyor runs underground from the old in-pit crusher and a new semi-mobile in-pit crusher installed at a depth of 285m within the mine. Another semi-mobile in-pit crusher was installed on the surface between the Aitik pit and the Salmijärvi satellite pit where waste stripping is processed.

Mining of raw materials is a process that consists of several stages. In open-pit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive strength, moisture …

ABSTRACT In-Pit Crushing and Conveying (IPCC) systems are receiving more attention today due to current characteristics of open-pit mining operations and what is expected to occur in the future. Today, it has become more necessary than ever to reduce the cost of truck haulage, which accounts for roughly half the operating costs of …

Open-pit ore is hauled to the primary gyratory crusher and the discharge fed to two secondary cone crushers. Due to the dry, dusty nature of the ore and the fine crush required to optimise leach recoveries, waterflush crushers are used to perform the tertiary crushing reduction of the ore to –12mm.
