2.1 Energy. Rock drilling, blasting, and comminution (crushing and grinding) consume a vast amount of energy in hard rock mines. As mentioned in Sect. 1, statistics from hard rock mines indicates that drilling and blasting consumes 2% and comminution does 53% of the total energy input in the whole production chain from mining to mineral …
In-pit crushing and conveying (IPCC) systems have drawn attention to the modern mining industry due to the numerous benefits than conventional truck-and-shovel systems. However, the implementation of the IPCC system can reduce mining flexibility and introduce additional mining sequence requirements. This paper investigates the long …
Figure. 2.Elevation View of Jaw Crusher II. Literature review Figure 1.Typical Jaw Crusher The working principal of Jaw Crusher is based on modern design. The crushing machine are consists of two Jaws, one jaw fixed and the other moving. The openings between the jaws are smaller at the bottom side and the wider at the top side.
Crushing is a size reduction process that plays a key role in both mineral processing and crushing–screening plant design. Investigations on rock crushability have become an important issue in mining operations and the manufacture of industrial crusher equipment. The main objective of this research is to quantify the crushability of hard …

1. Introduction. Since the first record in the 19th century, rockburst has gradually become a worldwide engineering problem. It is a sudden failure event of excavation-disturbed rock mass with the violent ejection of rock fragments (Cook, 1976; Hoek et al., 1995; Kaiser et al., 1996a; He, 2006; Mazaira and Konicek, 2015; Li et al., …
Purpose The aim of this literature review is to investigate the role of the beneficiation stage in the Life Cycle Assessment (LCA) of metals and minerals with a focus on the flotation process. Methods The systematic literature search included LCA studies comprising the beneficiation stage in their system boundaries and resulted in 29 studies …
Trucking costs can be significantly reduced by bringing the crushers inside the pits. The present paper aims to provide a comprehensive literature review of all aspects of technical, economic and sustainable development of in-pit crushing systems along with a statistical analysis of the systems since 1956 to the present.
