What are the conditions needed to reduce Iron(III)oxide, Maganese(IV)oxide & copper carbonate & copper(II)oxide
Iron= 700 degress+ & blast furnace& C monoxide or C | Mangaese = 1200+ blast furnace, CO or C| Copper Carbonate & Copper(II)oxide , carbon, malachite is ore
1 of 5
How do you turn sulfide ores into oxide ores?
Roasting in the air, produces sulfur dioxide
2 of 5
How do you produce tungsten??
with C but leaves inpurities, with H, for pure, 700+ blast furnace
3 of 5
How do you extract Aluminium
Electrolysis (Pass current though electrolyte (bauxite (ore) dissolved in cryolite), Positive anode electron flow to negative cathode, 1. Impurities removed, 2. Dissolved in molten cryolite, cathode Aluminium reduced, Anode Oxide ions oxidised.

How do you extract titanium?
Ore = Rutile, batch process used, 1. Heated with carbon & stream of chlorine gas at 900 celcius titanium chloride. 2. purify by fractional distillation in enert atomos argon. Chloride reduced in furnance 1000 degress heated with Na or Mg
