Based on known studies, a method is proposed to calculate the reaction-rate constants and apparent activation energy for dissolution of lead from copper concentrates. Lead was leached with I O and 40 percent ammonium acetate solutions at temperatures ranging from 293K to 323K. Based on the experimental results, the apparent activation energy was calculated for dissolution of lead from copper concentrate.}, type={Article}, title={Preliminary Studies of the Kinetics of Lead Dissolution from Copper Concentrate with the Aid or Ammonium Acetate}, URL={http://czasopisma.pan.pl/Content/131776/PDF/11_METALLURGY_47_1_2002_Sanak_Rydlewska_PRELIMINARY.pdf}, }
