F.K. Crundwell. The mechanism of dissolution of forsterite olivine and minerals of the orthosilicate group. Hydrometallurgy, 150 (2014) 68-82

by anna | Aug 4, 2023

The dissolution of forsterite and other minerals of the olivine and phenakite silicate groups are described by a novel mechanism of dissolution. For many of these minerals, the order of reaction with respect to H+ is close to 0.5 in the acidic region. The mechanism of...

L.J. Bryson, F.K. Crundwell. The anodic dissolution of pyrite in hydrochloric acid solutions. Hydrometallurgy, 43 (2014) 42-53

by anna | Aug 4, 2023

Pyrite is an abundant mineral, and its dissolution is important in the formation of acid mine drainage and the extraction of metals. It has also been considered as a candidate material for electrochemical solar cells. We studied the anodic processes on pyrite in...

CRUNDWELL, F.K. The dissolution and leaching of minerals. Mechanisms, myths and misunderstandings. Hydrometallurgy, 139 (2013) 132-148

by anna | Aug 4, 2023

The dissolution of minerals is of importance to a number of fields of endeavour. In particular, it is the rate of dis- solution that is important. Knowledge of the kinetics might allow the rate to be accelerated or retarded, depending on the field of endeavour. In...

CRUNDWELL, F.K., Effect of iron impurity in zinc sulphide concentrates on the rate of dissolution, AIChE Journal, 34 (1988) 1128-1134.

by anna | Aug 4, 2023

The rate of dissolution of sphalerite is shown to be directly proportional to the concentration of substitutional iron impurity in the solid. This is attributed to the formation of a narrow impurity band within the forbidden band gap of the sphalerite. The impurity...

CRUNDWELL, F.K. The Leaching Number:its definition and use in determining the performance of leaching reactors and autoclaves. Mineral Engineering in press 2005.

by anna | Aug 4, 2023

Leaching is a critical operation in hydrometallurgy. The performance of the leaching sections of a processing plant usually has a significant impact on the performance of the plant as a whole. In addition, leaching reactors are usually complex, involving multiple...
