2021-5-8 Another method for the separation of gold and silver is the so-called cyanide process. The Parkes process, which is based on silver being soluble in molten zinc while lead is not, is used to free silver from lead ores. Since almost all the metals are found combined with other elements in nature, chemical reactions are required to set them free.

Separation of zirconium and hafnium using Diphonix® chelating . Feb 01, 2009 1. Introduction. Hafnium occurs in all zirconium ores in the range of 23% but the use of these elements in the nuclear industry requires that reactor grade zirconium contains less than 100 ppm of hafnium, which is difficult because of their similar chemical properties resulting from almost identical atomic and ...

Examples of Metal Ores. The term ore is used to refer to a rock that contains minerals such as metals. In general, ores are oxides, sulfides, silicates or “native metals," those found in nature. Oxides and sulfides are called such because the minerals contain oxygen or sulfur, respectively, which has formed a ...
