separation de cassiterite

  • Cassiterite Wikipedia

    Cassiterite is a tin oxide mineral, SnO 2.It is generally opaque, but it is translucent in thin crystals.Its luster and multiple crystal faces produce a desirable gem. Cassiterite has been the chief tin ore throughout ancient history and remains the most important source of tin today.

  • Electrostatic Separation Procedure

    Separation of minerals utilizing differences in their electrical properties may be carried out using an electrostatic separator. It will separate electrical conductors (minerals such as cassiterite and rutile) from those that are electrical non-conductors (minerals such as zircon and siderite). The principle of separation is that as the particles to be treated are passed through an intense
