Factors Controlling the Strength of Weak Rock Masses: For the purposes of this paper a weak rock mass is defined as any rock mass in which
Effect of Temperature and Acid Concentration: The effect of temperature on the leaching behavior of copper and zinc is shown by the data in Figures 1
This paper describes a new development in the cyanidation of gold ores, which we expect will result in a major improvement in the way many
Because of the nature of the breakage in the Barmac vertical spindle impactor, the 80% reduction ratio is very small, so that when the energy
An effective technique has been developed to elute ion exchange resins loaded in the carbonate leaching process for uranium recovery. The procedure involved elution with
The flotation behaviors of pyrite and pyrrhotite in a Hallimond tube were correlated with the galvanic role they developed in two- and three-electrode combinations with
This paper presents results of ongoing research to develop an in-situ leaching process for Michigan copper sulfide ores. The objectives of the work presented here
A selective dolomite flotation process has recently been developed at the University of Florida whereby a two stage conditioning technique is utilized to remove MgO
The density of a Flocculant is usually evaluated by measuring its buoyant density while settling in a quiescent column. An equation of the general form
The flotation of sylvite (KCl) and also some accessory minerals (e.g. kieserite, langbeinite) from crude potash salts are processes used to a large extent all
