- This paper describes two studies that have been performed to evaluate and simulate flotation processes. The software used is mainly MATBAL and USIM PAC. Two flotation plants have been sampled and evaluated: the LKAB apatite flotation plant in Kiruna and the BOLIDEN copper sulfide flotation plant in Aitik. It is shown that these methods when implemented properly provide a fast and cost effective tool for optimizing the process as well as a better understanding of the process.

- The influence of reagents dosage, pH, temperature, and particle size on the kinetics of apatite flotation response from magnetite has been investigated. The first-order models characterizing rectangular distribution and fast and slow distributions (F-S model) of floatabilities gave an excellent fit to the results of apatite flotation when compared to other models. However, the latter model is found to be better than the former in the goodness of fit and also in the description of flotation performance. The kinetic parameters in the F-S model are estimated by using a nonlinear least squares fitting program. The ratio of fast and slow rate constants is observed to be an important parameter for identifying the optimum levels of the variables and to outline the selectivity between apatite and magnetite. The influence of collector dosage is realized from the model parameters by relating it to the fraction of slow- floating particles. An attempt has been made to describe the apatite flotation behavior with the determined model parameters.

- The article consists of a general review of developments in gravity concentration and a more detailed section on the authors' own research. Among subjects covered are: application and properties of the Reichert cone concentrator; dynamic flow characteristics of thin films; influence of roughness profiles of concentrating surface in slime gravity concentration; and influence of electrolytes in slime gravity concentration.
