In the previous chapter the influence of the various physical quantities defining the mill and mill charge has been studied in connection with the performance
The control of pH in solvent extraction circuits is an old technique but one which has a large potential for future use. The equilibrium position
The dependence of the power demand of a mill on the nature of the pulp does not appear to have received a great deal of study,
To insure the continuing viability of the domestic minerals and materials economy and the maintenance of an adequate minerals base, the U.S. Department of the
In recent years interest in hydrometallurgy, particularly in the case of in-situ leaching and solution mining has remained at a high level. There are several
It has long been recognized that the 9 million tons of lead ore mined annually from Missouri’s Lead Belt (83 pct of the U.S. domestic
The analysis of particle size distributions has become increasingly important in industrial processes. Particle size is recognized to be fundamental to the control of operations
In the commercial dump leaching of copper, two methods have been generally accepted as a means for recovering copper from pregnant leach liquors. The oldest
The Bureau of Mines has funded an extensive research program to develop improved scrubbers for coal mine applications. This work shows that scrubbers can offer
The kinetics of solvent extraction with hydroxyoximes are complex, involving mass transfer with chemical reaction in a heterogeneous system. One is therefore faced with a
