Cupriferous iron ore

In extractive metallurgy, for instance, certain low-grade copper ores could be leached with acid or ammoniacal solution advantageously in the fluidized state cupriferous iron ores, after sulfatizing roasting, could have their copper values recovered selectively by leaching with a very dilute acid (Yu et al., 1964) ... 

An alternate process for winning copper from cupriferous iron ore was segregation roasting, in which the hot ore was mixed with small amounts of common salt and powdered coal, in order to transport the copper content of the ore via gaseous copper chlorides to the coal particles, where they were reduced in situ to the metal. The copper-coated char could be concentrated by... 

A 15-ton-per-day plant in Dayeh prepares a cupriferous iron ore for extraction of its copper content, prior to smelting in a blast furnace, by subjecting the ore to a sulfatizing roast.
