    The amount of treatment needed depends on the grade of ore and type of deposit. Tin Smelting and Refining Once a tin concentrate of the required purity has been obtained (55 to 75% SnO2), it is sent to a smelter who smelts it into crude tin metal by removing the oxygen from the mineral.

  • Ancient Metallurgy

    Increasing the amount of tin in the alloy much above 10% produces greater brittleness, and tools made that way easily break. However alloys with more tin —potin (up to 20% tin) and speculum (more than 30% tin)— were used in some parts of Europe for early

    Tin ore from later medieval and early post-medieval extraction sites was processed and smelted using water-powered tin mills sited nearby. In the 18th century, ore extraction and processing rapidly expanded to meet growing demands, aided and promoted by technological development, with ore shipped to Bristol and later South Wales for smelting.

  • Dartmoor tin-mining

    The Dartmoor tin industry declined in importance during the early 18th century and had fallen to nothing by 1730. This was due to a number of factors, but the most important was likely to be the exhaustion of the easily accessible deposits. It was not until the Industrial Revolution fuelled demand for all metals and also provided the technology to mine them that mining resumed on the moor on ...

  • Extraction of tin from its ores

    Abstract: A process for the direct recovery of tin, as an organo hydrocarbyl tin compound, from reduced but unrefined tin ores and ore slags is described, wherein the ore is reacted directly with a hydrocarbyl halide to form an organo hydrocarbyl tin compound which can then easily be removed and separated from the tin-depleted ore residue.

    An ore containing 1% sulphur will produce a mass pull of approximately 5% by weight to a bulk flotation concentrate where recovery is the key driver. If this ore also contains 1g/t Au (for GSR =1), and 90% recovery to concentrate is achieved, then 0.90g will be recovered and with a concentration ratio of 20 (5% to concentrate) this corresponds to 18g/t Au in concentrate.
