Available in PDF, EPUB and Kindle. Book excerpt: Nothing set the world in motion like gold. Between the discovery of California placer gold in 1848 and the rush to Alaska fifty years later, the search for the precious yellow metal accelerated worldwide circulations of people, goods, capital, and technologies. A Global History of Gold Rushes brings together historians of the United States, Africa, Australasia, and the Pacific World to tell the rich story of these nineteenth century gold rushes from a global perspective. Gold was central to the growth of capitalism: it whetted the appetites of empire builders, mobilized the integration of global markets and economies, profoundly affected the environment, and transformed large-scale migration patterns. Together these essays tell the story of fifty years that changed the world.

Download or read book Chemistry of Gold Extraction written by Mineekshi Awasthi and published by . This book was released on 2015-03 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold extraction or recovery from its ores may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques since the mid to late 20th century have generally only been the practice of artisan miners. Hydraulic mining was used widely in the Californian gold rush, and involved breaking down alluvial deposits with high-pressure jets of water. Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the 20th century where open pit and or sub-surface mining techniques are used.
