Applied mineralogy of refinery slags

The techniques of process mineralogy can be effectively applied to the study of slags. By these techniques, the minerals or phases, phase chemistry, phase abundance, associations, crystalline habit, grain size, microtextures, and causes for certain metallurgical problems, such as metal losses to the slags, can be readily deduced. This case history is an example of the application of process mineralogy to the study of metal losses in a slag from a secondary copper refinery.
