Chlorination of chalcopyrite concentrates [PDF]

Metallurgical and Materials Transactions B, 1999
The chlorination behaviors of two chalcopyrite concentrates and their pure constituents in Cl2+N2 were investigated by thermogravimetric analysis (TGA) in nonisothermal conditions up to 1000 °C. The effect of temperature on the reaction of chlorine with both concentrates was studied between 170 °C and 300 °C under isothermal conditions.
