A research program was conducted to improve processing technology for extracting alumina from nonbauxitic. The success of this program had provided the technology necessary for producing an
This paper presents a development of thickening theory which provides a reliable and easy-to-use method for determining the size of continuous thickeners from batch settling
Increasing capacity of bulk material handling systems creates difficult problems for accurate in-line material weight measurements. At the same time increasing system complexity and growing
The crushing plant simulator was utilized to evaluate the influence of major variables on the following responses: plant reduction ratio , weight % of -½
Currently, most coal mines rely primarily on two methods for controlling dust. The first utilizes large volumes of outside air to ventilate and dilute the
Two of the missions of the Bureau of Mines are to conserve scarce, costly metals and to reduce pollution. In accordance with these missions, the
Disposal of the salt slag produced during the processing of aluminum dross and scrap is of particular interest to the secondary aluminum industry. Melting of
This report describes possible material application as oxygen electrode catalysts. The ultimate objective was to assess the potential of abundant, less costly materials as substitutes
The factors upon which the rate of flow of the pulp through a mill depends appear not to have received extensive investigation. In an article
The phenomenon of “surging” in a mill is a subject upon which very little has been written; presumably because it is a condition which cannot be
