Mineral comminution is an important and expensive industrial process and modern comminution circuits are complex. There is considerable economic incentive to optimise circuit design and

This report briefly reviews the essential features of moment analysis and describes extension of this method to size reduction by ball mill grinding. Method of
The intent of this paper is to try to answer the complex question: “How much grinding capacity should be designed into a new mining –
In discussing the open storage dust problem and possible solutions, one obvious question arises – what are the economics of placing large bulk storage under

The process parameters for effective utilization of nitric acid as an oxidant for copper-iron sulfides have been developed. Leaching variables found to be important were

Stable colloidal solutions of ferromagnetic or ferrimagnetic materials are called magnetic fluids. About two generations ago, suspensions of relatively large micron-sized ferromagnetic particles in oil

The HYGAS Process is one of several coal conversion processes now under development within the United States and is the most advanced in development. It

In essence, any magnetic separator operates on the basis of imparting a preferential magnetic force on particles of higher magnetic susceptibility which are to be

Incineration has, in recent years, been considered by many as a major source of air pollution. However, a number of reports refute this belief. The
