  • Cassiterite Wikipedia

    Most sources of cassiterite today are found in alluvial or placer deposits containing the resistant weathered grains. The best sources of primary cassiterite are found in the tin mines of Bolivia, where it is found in hydrothermal veins. Rwanda has a nascent cassiterite mining industry. Fighting over cassiterite deposits (particularly in Walikale) is a major cause of the conflict waged in eastern parts of the Democratic Republic of the Congo. This has led to cassiterite being considered a conflict mineral.

    Cassiterite is the main ore needed to extract tin (Gladwell et al., 1981). Fig. 3.8 presents the flow sheet showing the major steps of tin extraction. Fig. 3.8. Flow sheet of major steps of tin extraction. In the conventional reverberatory furnace process, cassiterite (SnO 2) is reduced to tin metal by heating with carbon at 1200–1300°C (2192–2372°F). Tin concentrate is smelted to

  • Cassiterite: The tin mineral cassiterite information and

    Cassiterite is the best-known tin mineral. It has been used as the chief ore of tin from early history throughout the ages, and remains so even today. Some of the economical Cassiterite deposits exist in placer stream deposits where this very heavy mineral collects as rounded waterworn pebbles. The name Cassiterite is derived from the Greek "kassiteros", meaning tin.

    In this passage, we will introduce you the cassiterite extraction technology. 1.Cassiterite gravity separation. The density of cassiterite is bigger than its gangue minerals. Therefore, gravity separation is the main production way of tin concentrates. The gravity of cassiterite is mainly ore sorting. Multiple grinding and multiple processing technologies are used as the processing flow of

  • Tin Extraction on Dartmoor

    Consequently, the only cassiterite available in many cases was lode material, which could only be recovered through the expansion of hard rock mining. The tin lodes had often been exposed by streaming or were located by searching for shode in the streams. The lodes could then be worked open cast from the surface leaving long scars on the landscape known as 'beams'; Gibby Beam etc or 'gerts': T

  • Dartmoor tin-mining Wikipedia

    Tin is smelted from cassiterite, a mineral found in hydrothermal veins in granite, and the uplands of Dartmoor were a particularly productive area. The techniques used for the extraction of tin from Dartmoor followed a progression from streaming through open cast mining to underground mining. Today, there are extensive archaeological remains of these three phases of the industry, as well as of

    28/05/2009· The Cassiterite is then mixed with approximately equal volumes of charcoal dust and a mixture of Sodium and Potassium carbonates (as a flux). The crucible used must have a lid to prevent atmospheric Oxygen from forming excessive Carbon dioxide. During smelting, the flux helps to remove impurities from the metal being formed. The overall reaction (upon heating) is: SnO2 (s) + 2 C (s) -->
