The design of an autoclave for studying hydrometallurgical reactions

An autoclave which may be used for studying hydrometallurgical reactions above 373 K and 1 atm is described. Its design is such that solid and/or liquid reactants may be added whenever desired. Portions of the reacting solution may be removed as required for analysis. The autoclave has been used to study the kinetics of the reactions between several aqueous solutions and metal sulphide ores. Results of a preliminary investigation between acidified copper sulphate and pentlandite are presented.
