A general awakening of interest among mill men concerning the mechanical efficiencies of their crushing machines is evident from a perusal of the recent files of
Most metallurgists appreciate the great need of a process for the extraction and recovery of valuable metals from complex ore, where the presence of one metal
This plant, near Marysville, Montana, was planned to treat the ore from the Piegan and Gloster mines, the latter being one of the early and famous
The object of this paper is to offer some suggestions to assist metallurgists to supervise the operations of flotation plants. We do not yet thoroughly understand
In the laboratory work described in the following pages, a 4 ½-ft. Hardinge mill with three removable cylindrical sections, 16 in. each in length, was used.
During construction work at a mill, the metallurgical engineer in charge, ran a series of experiments on settling. His tests proved that deep settling tanks were
In order to develop rational methods of measurement and laboratory testing, it becomes necessary to study the general phenomena of settling rates. Since it was desired

Very little is documented about Gold Room Security due to the sensitivity of people around it. At the same time, when establishing a new operation it
When estimating the capacity of crushers under given conditions, it is necessary to employ an empirical factor which has here been designated by the letter
