Metallic resources in smartphones ScienceDirect

53 metallic elements from smartphones were investigated with regard to metal prices, metal production, and content in comparison to mined ores. The metal content of the 7.42 billion smartphone devices sold from 2012 to 2017 could theoretically maintain the global supply for 91 days for Ga, 73 days for Ta, 23 days for Pd, 14 days for Au, and 6

Geochemistry of Gold Ores Mined During Celtic Times

The Celtic culture of Western Europe left magnificent gold objects, such as jewellery and weapons from nobility graves and hoarded coins, as well as field evidence of pre-Roman gold mining and metallurgical workshops that attest to the mining of local ores. This is the case of Central France where many precious metallic ores have been mined throughout the ages from the Prehistoric times onwards.

The determination of metallic iron, nickel and cobalt

A procedure is described for the determination of metallic iron, nickel and cobalt in reduced ores and oxides. The metallic phases are dissolved in brominemethanol solution, excess of bromine is destroyed by reaction with hydroxylamine hydrochloride and the analysis is completed by atomic absorption spectrophotometry.

Minnesota produced 76 percent of the national output of useable ore while Michigan accounted for 23 percent. The production process typically involves four stages, and taconite iron ore is the

Silver Ores and Silver Bearing Minerals Nevada

2014-6-22  Silver-lead ores form a widely distributed class in the Cordilleran region of the United States and supply most of the lead mined in this country. Prominent deposits have been mined in Colorado, Idaho, and Utah, but are also known in New Mexico, Montana, Wyoming, Nevada, Arizona, California, and South Dakota.

How to Detect Silver in the Ground at a Silver Mine

The silvery metallic ores that contain silver do not get their color and texture from the silver, but from lead content. Watch for rocks with crystals. Silver is often found in conjunction with quartz and rubies. Rich silver deposits are found in rocks with a mixture of red, pink, and dark sooty crystals. The silver
