Recovering Lithium from Clays

The McDermitt clay contains lithium principally as hectorite. To convert the lithium to Li2SO4, the clay was mixed with limestone and gypsum and roasted. As received, the clay was soft and friable and required no heavy crushing. However, it …

The Interaction of Clay Dispersants and Grinding …

With the depletion of high quality ores and an increased demand of metals by society, low quality ores have been processed by the industry. This includes processing of clay ores and grinding the ores to smaller sizes. In an attempt to address the issue relating to processing clay ores, Newcrest's Telfer operation has examined clay dispersants in the flotation of high clay bearing copper and ...

grinding operation. It involves coarse crushing followed by wet grinding. Crushing is usually a dry operation that utilizes water sprays to control dust. Primary crushing is often performed at the mine site, followed by additional crushing at the mill. The crushed ore is mixed with water and initial flotation reagents to form slurry.
