As this particular product holds a place by itself, it seems desirable to give a paper dealing especially with it as a corollary to my
Many power-based grinding models exist, and most operators are familiar with Fred Bond’s “third theory”. Bond’s model is most commonly used to describe primary
An increasing demand for metals in general, and higher purity metals in particular, decreasing ore grades and more stringent environmental regulations have driven, and will
Under the above title it is desired to bring to the attention of assayers a short-cut method which has been perfected by Mr. A. S.
So many emergencies that crop up in mining necessitate a departure from ordinary methods that the writer has been led to illustrate a few of
Concentrating-Machinery has been wonderfully improved during the past few years both in technical efficiency and in economy of power; and, in the writer’s opinion, the
It has been explained in an earlier talk that solvent extraction in the copper industry is used to convert impure, and frequently very dilute copper
In recent years, the principle and theory behind solvent extraction has gained wide acceptance as one of the new tools of modern hydro-metallurgy. With the growing
