Potassium and sodium cyanide salts are water soluble, whereas mercury, copper, gold, and silver cyanide salts are poorly water soluble. Also, a number of cyanide-containing compounds, known as cyanogens, may release cyanide during metabolism.
Cyanide and cyanide-containing compounds are used in pesticides and fumigants, plastics, electroplating, photodeveloping and mining. Dye and drug companies also use cyanides. Some industrial processes, such as iron and steel production, chemical industries and …
A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols and numbers.
cyanide is dripped onto a heap of gold ore and left to percolate its way through the heap of gold ore. The dissolved gold in the form of the complex now needs to be separated out and recovered.
