Iron ore extraction techniques - ScienceDirect

2015-1-1  Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this ...

2017-3-27  Extraction of Metals. History ().. After the Bronze Age came the Iron Age. People discovered that a high temperature coal fire could be used for the extraction of iron from iron ore. The extraction of iron today is done in a blast furnace.. The Iron Age began in Asia and Africa in 1,100 B.C. and came to Britain in 500 B.C. In many ways, we are still in the Iron Age - take a look around.

Copper Precipitation Methods

2017-3-26  Sponge iron, when mixed with cuprous chloride 40 to 50 per cent, solids, gives a rapid and complete precipitation, with the evolution of considerable heat. The reaction is, Cu2Cl2 + Fe = 2Cu + FeCl2. It is evident from this reaction that only one-half as much iron is required, to precipitate the copper from cuprous chloride as from a cupric salt.
