| Abstract: | The effects of sulphuric acid excess coefficient and hydrochloric acid dosage,water dosage,leaching time and temperature on the leaching rate of pyrite cinder in mixed acid medium were studied.An orthogonal array(five factors in four levels) was employed to evaluate the influence of acid excess coefficient and hydrochloric acid dosage,water dosage,leaching time and temperature on the leaching rate of pyrite cinder.Statistical techniques were used to determine that temperature was the most significant factor... |
