The roasting of precipitated copper sulphide in a current of air has been investigated by thermogravimetric analysis in the temperature range 150–800° under isothermal conditions. Chemical analysis of the products was carried out at intervals in e

A new method is described for the production of manganous sulphate from low-grade manganese ores. The ore is first treated with a calculated amount of concentrated sulphuric acid at 200–220° to form manganic and ferric sulphates, and then heated a

The kinetics of the isothermal dehydration of zinc and magnesium sulphate heptahydrates were studied both in vacuo and in the presence of air. Decomposition in vacuo followed a first-order mechanism, while that in the presence of air followed an inte

In previous papers of this series evidence was advanced that: (i) The expansion which unactivated wood charcoal undergoes when adsorbing gases or vapours is directly proportional to its surface (free) energy lowering (Parts II and III). (ii) The Gibb

No simple correlation was found between the heats of wetting in methanol of a number of carbons, prepared from corn cobs and date pits under varying conditions, and the specific surface areas of the carbons calculated from the adsorption isotherms of
