Abstract

The authors conducted multifactorial experiments on oxidizing and chloridizing roasting of pelletized rough copper sulphide concentrates in order to identify the influence of air temperature and rate of filtration through a sample, the size of pellets, the sulphur content and pellet moisture on maximum roasting temperature. The mathematical models were developed to determine optimal areas of roasting and calculate the apparent activation energy by applying the Kissinger method.

Keywords

Pellets, oxidizing and chloridizing roasting, shaft furnace, multifactor model, graph, diffusion mode.
