The Correct Answer is (D) Cassiterite ore, a primary source of tin, undergoes a series of extraction steps to obtain the desired metal. Cassiterite, also known as tin stone, is a mineral form of tin oxide (SnO 2) found in various tin-bearing deposits. Tin is extracted from cassiterite ore through a sequence of extraction processes.

Cassiterite is a mineral composed of tin oxide (SnO2) and is the primary ore of tin. It has a high density and a hardness of 6 to 7 on the Mohs scale, making it relatively resistant to weathering and erosion. The name "cassiterite" is derived from the Greek word "kassíteros," which means tin.

SnO2 + 2C Sn + 2CO. Crude tin so obtained is contaminated with iron, copper, lead and other metals. It is, therefore, remelted on an inclined furnace. The process is called liquation. The easily fusible tin melts away and the less fusible impurities are left behind. Molten tin is finally stirred with green poles of wood in contact with air.

The process is called liquation. The easily fusible tin metals away and the less fusible impurities are left behind. Molten tin is finally stirred with green poles of wood in contact with air. In this process, any remaining metal impurities are oxidized forming a scum, which rises to the surface and is removed. This process is called polling.
