In Early Mining Towns in the Amercian West – How Did the Miners Get Water? Were Their Supplies Low? HELP!?Posted by goldpanner in Gold Panning FAQ, tags: Amercian, early, Help, miners, mining, supplies, their, towns, water, Were, WestQuestion by MattMan: In early mining towns in the Amercian West - How did the miners get water? Were their supplies low? HELP!? In the American West, when there was gold mining going on did the miners get their water by irrigation systems, from the mountains? Or did they Pan for it, and where? PLEASE HELP!! I really need to get this done TONIGHT. Thank you. Best answer: Answer by Vince M The water would typically be a river or stream or, in some cases a lakeshore. If there was an irrigation system available, it would mean that someone already owned that land and was trying to grow crops on it. That owner would most certainly NOT welcome miners coming onto that property and taking out valuable gold. Miners did, often band together to move water to a more convienient location by building sluices, or wooden aquedutcts to a place where they could screen the silt, carried by these sluices for the heavier minerals, such as gold. In certain kinds of mining operations, called placer mining, water was pumped up to a high pressure, and hoses were used to blast cliffsides, hopefully containing gold and gold bearing rocks to be sluiced and panned downstream.

Republished by Blog Post Promoter Question by Spunky: Gold Shaft Mining 1850's and Now? Best answer: Answer by Tashkent T In 1850, there were gold mines that accessed ore both through horizontal development into the sides of hills (adits) and by vertical drop shafts. Sometimes, people would have to climb down into their work places - this still goes on within the informal mining sector in parts of Africa and Asia. Within the formal sector, small drop shafts (by hoist) and adits continue to be used. The biggest difference today, is a breakthrough in mineral processing technology that took place in 1886 which, interestingly was the same year that the gold deposits of the Witwatersrand basin in South Africa were first significantly worked. The technological breakthrough was that extraction of the gold through dissolution in sodium cyanide meant that gold need no longer be recovered by gravitational separation. In practise this meant that mining could continue to depth well below the water table / oxide cap into the sulphide zone. Gold ore within the sulphide zone is usually (but not essentially) occuring as microscopic particles within such sulphides as pyrite and arsenopyrite. By crushing this ore and dissolving in cyanide, the gold can now be economically recovered. In 1850, gold mining did not normally go beyond the oxide zone. Within the oxide zone, the original pyrite mineralogy has been oxidised to iron oxides and was therefore amenable to gravitational separation. A further problem in 1850 was the effeciency of mine pumps. Today, mining at 3000 metres below surface does not prove a problem as dewatering and cool air circulation make such work not just possible but relatively easy. In 1850, it was not just the change to sulphide mineralogy that posed a problem but inefficient pumps also made access to the lowest levels difficult too. Know better?
