✦ Synopsis

Oxidation of zinc sulphide pellets is carried out in the ranges of 6OS826"C temperature, 0.3-0.5 porosity and IS-50 minutes of reaction time. An experimental technique is employed to simultaneously determine the rate of weigh1 loss of the solid and conversions of the solid reactant at various levels in the pellet for different reaction times. A structural model is used to explain the experimental results. It is found that the model predicts hoth the experimental results obtained under various conditions reasonably well.

A promising method for controlling sulphur oxides emission during the roasting of metal sulphides is with the use of lime-coated sulphide pellets. The roasting of lime-coated zinc sulphide concentrate pellets in air at temperatures between 700 and 800Β°C is investigated. The experimental data show th
