The Old Copper Complex in North America has been radiometrically dated to 9500 BP—i.e., about 7480 BCE—making it one of the oldest known examples of copper extraction in the world. The earliest evidence of cold-hammering of native copper comes from the excavation at Çayönü Tepesi in eastern Anatolia, which dates between 7200 to 6600 BCE. Among the various items …

Mineralogy is the systematic study that deals with the characteristics of the individual and group of minerals. The mineralogy has many more scientific branches. The first detailed narratives considering all the minerals at that time authored by Dana (1951), and with a subsequent enhanced update by Gaines et al. (1997).The concept of mineralogy (minerals) and petrology …

Cathodic inhibitors are soluble at average water pH but will form a protective layer over cathodic surfaces by producing an insoluble compound that is not an electricity conductor, at high pH values. Examples of cathodic inhibitors : zinc ions (Zn 2+); polyphosphates (in conjunction with Ca 2+); phosphonates (in conjunction with Ca 2+).

Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify rapidly while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from 0.5 µm to 300 µm. The major consequence of the rapid cooling is that few minerals have time to crystallize, and …
