Summary
[edit]DescriptionBrunton Calciner - geograph.org.uk - 588912.jpg |
English: Brunton Calciner (Remains associated with the Brunton Calciner on the Wheal Busy site)
588947 : Previous -- (1 of 6) -- Next : 588921 These remains can be view viewed from 588873. William Brunton patented his 'Brunton Calciner' in 1829 and greatly enhanced the speed at which arsenic (an impurity) could be removed from ore. Where the arsenic contamination was high it became economic to recover the arsenic as a by-product.
