Extracted text: A wet copper concentrate initially at 35 C consists of chalcopyrite with wH20 = 0.095. It is to be dried in a fluidized bed reactor by superheated steam entering at 240 °C and 20 bar. The discharge temperature of the dry chalcopyrite and steam is 115 °C and 1 bar. Calculate the mass of steam required per kg of moist chalcopyrite.
