Mining is a critical industry in Chile, so to understand the impact of lean production, this research provides details regarding the implementation of lean production methodologies in three underground mining development projects belonging to a Chilean mining company.
2001-1-1 This landscape includes the only intact cluster of historic hard-rock metal-mine plant buildings in the region. The Ely mine orebody was discovered in 1813 and explored during the 1830s, but it was most active between the mid-1850s and about 1905. Mining began seriously in 1853 with the incorporation of the Vermont Copper Mining Company.
The Magmont-West mine area is located in southeastern Missouri approximately 90 miles southwest of St. Louis along the western edge of the Viburnum Trend or New Lead Belt. During a Precambrian copper-iron exploration program which was begun in 1956 by American Zinc Company, lead-zinc mineralization was encountered in the Upper Cambrian
2013-1-24 A discourse fostered by Western politicians and media of Chinese copper mining in Zambia has been central to global discussions of China-in-Africa since the mid-2000s. Based in the West’s putative strategic rivalry with China, the discourse also invokes racial
2009-4-24 – The purpose of this paper is to provide an overview of recent developments in employment relations in Chile, focusing on recent episodes of contract labour mobilisation in the forestry and copper mining sectors., This paper is based on a consolidation of existing evidence from a range of primary, secondary and tertiary sources., The paper demonstrates the inadequacy of Chile's
2012-1-1 The Cu-Au-Mo deposit lies at the center of a large polymetallic district, which includes proximal Pb-Zn-Ag replacement and distal sediment-hosted gold mineralization. Open-pit copper mining commenced in 1906 and through 2011 has produced 2.666 billion tonnes of
2001-3-1 Chuquicamata, in northern Chile, is the world’s greatest copper orebody. It was controlled, from the initial intrusions (probably at 36–33 Ma) through mineralization (last major hydrothermal event at 31 Ma) to postmineral brecciation and offset, by the West fault system. East
Critical distance between copper mining roadway and a vertical water-blocked body It is vital to determine the critical distance between a mining roadway and a natural vertical water-blocked body (VWBB) where a substantial water level difference and seepage gradient have developed between the two sides of the VWBB.

2012-1-1 The Kupferschiefer of northern central Europe is not only one of the largest sediment-hosted accumulations of copper ores worldwide (largest 1% of deposits with >60 Mt contained Cu) but has also one of the longest continuously documented mining histories, starting from at least 1,199 A.D. in
2007-10-10 A copper deposit case study shows that, keeping the metal price escalation at a minimum, the impact of mining and milling costs escalation is relatively higher than refining and administrative costs. Hence, a high‐escalation rate in mining and milling costs may change an economic operation into an

Based on original documents from the Mexican-American War (1846-1848), this film tells the story of the young warrior Ulzana, who is out to avenge the extermination of his tribe. In 1822, the Mimbreno Apache Indians enter into an agreement with a Mexican mining company, relinquishing all mining rights and guaranteeing the safety of the copper
