Abstract

Ores are treated with nitric acid of at least 40 per cent in the presence of iron or acid-soluble iron compounds equivalent to the metals other than iron in the ore, the iron nitrate produced being the effective attacking agent. After the separation of the iron hydrate, the nitrate solution may be treated with sulphuric acid to precipitate the lead and then by cementation to obtain first the silver and then the copper; or the solution after the removal of the lead and silver may be treated with sulphuric acid to obtain crystallizable sulphates which, owing to their water of crystallization, leave the liberated nitric acid in a concentrated state. Alternatively, instead of cementation as above described, the metals may be obtained by fractional electrolysis.
