Gold - USGS

Gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from low-grade ore. The degree of purity of native gold, bullion (bars or ingots of unrefined gold), and refined gold is stated in terms of gold content.

Gold: History of Use, Mining, Prospecting, Assay Production

The degree of purity of native gold, bullion (bars or ingots of unrefined gold), and refined gold is stated in terms of gold content. "Fineness" defines gold content in parts per thousand. For example, a gold nugget containing 885 parts of pure gold and 115 parts of other metals , such as silver and copper , would be considered 885-fine.

Precious metals may be recovered from the gold ore or from refining processes of base metals such as copper and lead. Because these are distinct recovery methods, they are discussed separately. 7.1.2.1 Precious Metal Recovery from Ores In 2000, gold was produced at 641 load mines; about a dozen large placer mines; and numerous small placer mines.

Magnetometer - Wikipedia

In a magnetically neutral background, the input and output currents match. However, when the core is exposed to a background field, it is more easily saturated in alignment with that field and less easily saturated in opposition to it. Hence the alternating magnetic field, and the induced output current, are out of step with the input current.

NAICS Code Description NAICS Association

The output of smelting and refining, usually in ingot form, is used in rolling, drawing, and extruding operations to make sheet, strip, bar, rod, or wire, and in molten form to make castings and other basic metal products. Primary manufacturing of ferrous and nonferrous metals begins with ore or concentrate as the primary input.
