Silver-reductor method for determination of iron in iron ores and iron-ore sinters
Talanta, 1980A new technique for the quick dissolution of iron ore, magnetite and sinter products has been developed. The sample is dissolved with thioglycollic acid and hydrochloric acid, the excess of thioglycollic acid is oxidized, and the iron is reduced in the silver reductor.

Abstract It seems that implements and weapolas made of iron came into use in China about a thousand years later than in such ancient countries as Egypt or Mesopotamia. The true iron age began in these countries roughly in the middle of the second millennium B.C. whereas in China it did not begin until the middle of the first millennium P.
