The journey of the ore

Follow a piece of ore from the pit. The line moves as you scroll, and at every station the ore gets a little whiter.

  1. Excavator loading magnesite onto a truck in the open pit

    Open pit

    Magnesite ore is extracted run-of-mine from the benched open pit on our licensed site.

  2. Crushing and screening plant

    Crushing

    Run-of-mine ore is reduced to workable sizes in the crushers.

  3. Aerial view of the screening line

    Screening

    Screens split the material into two lines by grain size: 2–10 cm and 0.5–2 cm.

  4. Washing drum and conveyor

    Washing

    The washing drum removes clay and dust from the ore surface.

  5. Hand sorting magnesite on the picking belt

    Hand sorting

    Our teams sort the magnesite by hand using colour: the white stays, the gangue goes.

  6. Covered processing building

    Magnetic separation

    On the fine fraction, a magnetic separator captures impurities such as serpentine.

  7. Product and shipping

    Shipped to customers in Türkiye and abroad according to demand.
