schist mining plant

Schist - WikipediaThe graphitic schists may readily be believed to represent sediments once containing coal or plant remains; there are also schistose ironstones (hematite-schists), but metamorphic beds of salt or gypsum are exceedingly uncommon. Among schists of igneous origin there are the silky calc-schists, the foliated serpentines.schist mining plant,A Visit to the Kagem Open-pit Emerald Mine in Zambia | Research .Dec 31, 2014 . Once the ore is transported to the washing plant, it follows a process that is typical of sophisticated colored gemstone mining operations. Screens are used to break down the material by size and then washers remove the silt to expose the potential emerald-bearing schist for hand pickers to examine.
