    Aug 09, 2015  China clay mining is a complicated process which can be split into three distinct sections - opencast mining, refining and drying  Known as pit operations, this process firstly requires the removal of ground overlying the clay.China clay extracted from the deposits by mixing with water using jet water splashier. Forced water is sprayed on clay and mixed with water, this water plus clay slurry is pumped to ground level. In this slurry, the clay content is very low, generally below 10 percent. Then this slurry is sent to the net process.China Clay –Definition, Processing, Properties UsesTo increase the refractoriness of the material, fire clay often is calcined. Calcining eliminatesmoisture and organic material and causes a chemical reaction to occur between the alumina and silicain the clay, rendering a material (mullite) that is harder, denser, and more easily crushed than Figure 11.25-1.11.25 Clay Processing

  • Mining and Refining – Process

    Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.Bentonite (/ ˈ b ɛ n t ə n aɪ t /) is an absorbent swelling clay consisting mostly of montmorillonite.It usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to clay minerals. Bentonite beds are white or pale blue or green in fresh exposures, turning to a cream color and then yellow, red, or brown as the exposure is weathered further.Bentonite - WikipediaPegmatites are more expensive to process than brine, but typically have higher ore concentrations (0.60%). Lithium is also extracted from sedimentary rocks, including clays, which can have up to 0.7% concentrations, but this is a much less common form of deposit than brines or pegmatites (Gruber, 2011).Locations of Deposits
