An exploration program initiated by Johns-Manville Corp. resulted in the discovery of significant occurrences of platinum-group elements in the Stillwater complex of south-central Montana. The
The purpose of the Bureau research described in this report was to devise a procedure for producing TiCl4 from titaniferous raw materials, especially those that
The Sylvinite ores mined in conventional mines contain Sylvite (20 to 30% K2O), Halite, sometimes Carnallite and 1 to 5% insol. Liberation, in some cases,
The trend in the design of fine crushing plants is in the direction of the horizontal arrangement with all crushers on a single floor. Conveyors
Comprehensive underground hard rock mining studies pointed out that significant reductions in ore handling costs could be attained if portable, low headroom, hard rock crushers
Steady-State Pit Dewatering Simulations: Steady-state simulations of the observed potentiometric surface of the aquifer were used to calibrate the model. Calibration is the procedure by
This paper describes the production of cold or low temperature bonding method using sponge iron powder as a binder for iron bearing material after balling. Development
The answer to the question of how to economically move bulk materials for the industrial plant is an important facet of plant engineering. Should it
QUALITATIVE DETECTION Because of the distinctive colors of the precipitates formed, various cations have been proposed for the qualitative detection of the ferrocyanide ion. Since
It is generally agreed that the ferrocyanide ion is of a low order of oral toxicity, even in relatively large dosage. Kobert states that potassium
