Manganese Products, Inc. has developed a sulphurous-sulphuric acid leaching process for the recovery of manganese from low-grade, intermediate manganese ores. By the term “intermediate manganese
All of our larger domestic deposits of manganese are very low grade, but estimated tonnages in these deposits are large enough to constitute a potential
Figure 4 is a schematic diagram of a ball mill/cyclone control system. This diagram shows the instrumentation and the calculated variables used in the control
When a mineral particle is fractured, bonds between the atoms are broken. The unsatisfied forces that appear at the newly formed surface are considered to
Most papers on xanthate have dealt with principles rather than practice. On the assumption that many millmen are interested in knowing where and in what
Trough washers were among the earliest methods used for concentrating ores; they are referred to by Agricola about the middle of the sixteenth century as
The separation of minerals by flotation can be regarded as a rate process, with the extraction of any one mineral determined by its flotation rate,
A search of the literature reveals that no measurements have been made of the forces acting between a small solid particle whose surface is hydrophobic,
During the past year there have been a number of significant investigations that have furnished evidence on the driving forces governing grain growth and on
The nature of the atomic rearrangement involved in the precipitation of the compound γ-Cu-Be from supersaturated solid solutions of the copper-base alloys has been the
