• SEPARATION TECHNIQUES

    SEPARATION TECHNIQUES If a substance does not dissolve in a solvent, we say that it is insoluble. For example, sand does not dissolve in water – it is insoluble. Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: • the sand stays behind in the filter paper (it becomes the ...

    Mining Techniques. Mining techniques can be divided into two common excavation types: surface mining and subsurface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.

  • how to separate magnetite from iron ore

    Oct 04, 2018 Low intensity techniques are normally used on magnetite ore as an inexpensive and effective separation method. High intensity separators employ fields as strong as 1 Tesla to 2 Tesla. This method is used to separate weakly magnetic iron ores such as hematite, from nonmagnetic or less magnetic gangue materials.
