Excerpt: ... tailings contained, and seldom as much as two ounces of gold." Prof. Raymond's Report, 1870, page 364: --"It is impossible to state accurately what percentage of gold is lost in milling, as few assays are made either of the crude ore or of the tailings; but that a very large amount is lost can.not be doubted, and this loss probably varies from thirty to seventy per cent., according to the nature of the ore. None of the silver is saved except a small quantity, which being obtained in the gold, merely diminishes the value of the latter metal." Fossett's Colorado, page 292: --"It is estimated that more gold has been wasted in milling and has been washed down the creeks and gulches than has been saved." Albert Reiehenecker see Appendix, page 80 et seq). "The proportion of gold saved on the plates and tables varies, in a well-constructed mill, between thirty and fifty per cent. of the whole amount of gold in the quartz, and may average forty per cent." Article XII. THE PRESENT CONDITION OF INDUSTRIAL GOLD MINING. It will be apparent from these brief outlines that gold mining as an industrial pursuit encompasses interests of immense importance when the whole field of enterprise is brought into Tiew. The sources of the metal are practically beyond the measure of any method of calculation. The great extent of mineral area, the cosmical profusion displayed in nature with reference to all deposits of useful metals and substances, the expansive surface exploited and depths attained by practical working in widely-varying and separated localities, all tend to demonstrate the number and magnitude of workable veins of gold. In connection with this, it is also apparent that great progress has.been made in structural and...

Available in PDF, EPUB and Kindle. Book excerpt: The domestic gold mining industry has changed substantially as production has increased sharply since 1980. This thesis seeks to review the fundamental economic and technologic changes contributing to increased production and to present an analysis of the components of present mine supply. The sustained higher gold price in real terms has been the driving force behind rapidly increasing domestic gold production. Developments in open pit mining methods, heap leaching technology, and carbon-in-pulp technology have contributed to lower production costs. Higher prices and lower costs have resulted in very attractive profit margins, enabling the industry to raise substantial capital to develop new mines through equity offerings and gold loans. Numerous discoveries of large-tonnage, low-grade deposits in the Western United States, particularly Nevada, have resulted in many major mines commencing production since 1980. Nevada has rapidly become the dominant gold producing state, providing nearly 56% of total domestic output in 1987. The Carlin trend in northeast Nevada is now recognised as the largest proven gold belt in the western hemisphere. The other major gold producing states, in order of descending 1987 production, are California, South Dakota, Montana, Washington, Utah, Colorado, and Alaska.
