    An Investigation on Reaction Kinetics of Leaching Sb2S3

    Leaching Sb2S3 ores by acid FeCl3 solution is solid liquid phases second order reaction creating solid reactant. The kinetics investigation shows that the reaction is second order, its kinetics equation can be expressed as df/dt=K(1 f)2, the leaching activation energy is 53.34J/mol,which can be evaluated by measuring the kquot; value i.e. the velocity constant of apparent reaction at variable
