Reducing the iron content of kaolin from Milos, Greece, by a hydrometallurgical process
By S. G. Tsimas, A. K. Moutsatsou, G. K. Parissakis, M. A. Komiotou
For Greek kaolin producers, a considerable proportion of whose output is from deposits containing more than 4 wt% Fe2O3, the colouring resulting from iron oxide impurity represents a serious problem t

Design of longwall face support by use of neural network models
By Jinsheng Chen, S. S. Peng
The relationship between support performance parameters and parameters representative of mining and roof conditions is characterised by uncertainty, non-linearity and dependence, so the theory of arti

Alkaline roasting of low-grade chromite
By G. X. Wang, R. E. Siemens, M. C. Fuerstenau, D. Chandra
Soda roasting of concentrates from Mouat, Montana, was performed in a temperature range of 450 to 650 degrees C and chromium was solubilised by water leaching at room temperature. It was found that hi
