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 content, capacity of crusher, abrasiveness

8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.

In open-pit mining, the mobile crusher can freely adjust the production position according to mining progress. The mobile crusher can crush ores such as gold ore, copper ore, iron ore, etc. to the required size, and then transports them to the ball mill through a conveyor belt for grinding and beneficiation.

Next. Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).

Disadvantages of open pit mining. One of the main disadvantages of this type of mining operation is the environmental impact it causes. Since cyanide, mercury and sulfuric acid are used to remove the wastewater, groundwater and air are contaminated as toxic dust . This is absorbed by animals and plants.

An open pit mine could recover almost 90% of the oil shale in a very thick deposit [17]. It is said that strip mining could provide an even higher recovery. Shown in Fig.8.8 is an open-pit mine used to explain the process of mining the oil shale.

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 mining operation. Trucking costs can be significantly reduced
