Preliminary Lithium Extraction Tests: In the preliminary McDermitt clay studies, several lithium extraction methods were investigated. Water disaggregation, hydrothermal treatment, acid leach, alkaline roast-water leach, sulfate
Electrowinning is an electrochemical operation employing an anode and cathode immersed in an electrolytic solution containing sulfuric acid and aqueous copper sulfate. When direct electrical
There is a growing interest in the use of fine grinding to produce ultrafine particles for applications such as direct firing of micronized coal. It
The present work was undertaken to develop a method to cathodically protect a ball mill to reduce materials loss from mill liners. The essential science
The pressure oxidation process is especially suitable for the sulfide type of refractory ores. It includes two stages of operation. First, the refractory ore is
Processes for gold extraction usually depend on how gold is associated with its environment. Although cyanide leaching remains the overwhelming option for the treatment of
Technology improvements in copper mining operations have been the key factor for increasing productivity. Beyond dump leaching, the industry will increasingly use various heap leach
The two size reduction/froth flotation interactions described in this paper are strongly related to optimally using the inherent electrochemical surface rearrangements that occur on selected
The direct conversion of mineral concentrates into useful ceramic materials, without several intermediate processes, is of great interest to the materials community. Recently there has
