This invention is of importance for the large scale synthesis of
be profitably extractedup to one fortieth (1/40) of a grain of gold per ton of water. Gold is generally found in two types of deposits lode (vein) or placer deposits; the mining technique used to extract the gold depends upon the type of deposit.
Phosphorus is found in Group 15 (VA) of the periodic table. The periodic table is a chart that that shows how chemical elements are related to each other.
