  • extraction of metal from the ore cassiterite involves

    Tin is obtained by reducing the ore cassiterite with coal in a reverberatory furnace; Limestone is added to produce a slag with the impurities, which can be removed. Crude tin so obtained is contaminated with iron, lead and other metals. It is, therefore, remelted on an inclined furnace. The process is

  • Extraction of metal from the ore cassiterite involves

    The important ore of tin is cassiterite (S n O 2). Tin is extracted from cassiterite ore by carbon reduction method in a blast furnace. S n O 2 + 2 C → S n + 2 C O The product often contain traces of iron which is removed by blowing air through the melt to oxidise to FeO which then floats to the surface.

    The mining of Cassiterite started in 1904 in Jos. But during the mid-1920s more cassiterite was discovered which resulted in more mechanized extraction techniques to meet up with the high demand for tin by 1960s however, the demand increased, got to a peak and gradually declined in the late 1980s 11.

  • Benefits of cassiterite mining by artisanal miners in Jos

    7/11/2020· Artisanal mining of cassiterite is one tedious activity that is done daily. It involves daily extraction of economic mineral deposits through the use of primitive tools like shovel, digger, and spade. The continuous extractive act by these artisanal miners tends not to bother the Government of Nigeria and as such, there is no detailed record that collates the quantity of cassiterite mined and

  • How to Extract Tin from Tin Oxide Ore?

    Tin exists almost in the form of cassiterite (tin oxide) in the earth's crust. Its density is relatively large, so gravity separation is most used for tin extraction. In the pre-dressing stage of tin oxide ore, the common equipments are trammel screen, cyclones, rod mills and other equipment.
