ArticleName Autoclave leaching of low-quality zinc concentrate
ArticleAuthor Shpaer V. M., Kalashnikova M. I.

Influence of temperature and oxygen pressure on process speed is difficult in character at autoclave leaching of low-quality zinc concentrate. Values of apparent activation energy and apparent value of oxygen are inconstant, they depend of oxidation depth of minerals and can attain to anomalous high values. Leaching proceed at capping of diffusion “inside firm substance” and rarely in transition diffusion-kinetic zone.
