A lease for Grit and Gravels Mine in Shropshire in March 1825 included
sulpher and leases for other mines, eg Ovenpipe, included mundic, to what
extent commercial
quantities of the latter were mined in the county I do not know.
At Wilderley Mine also in Shropshire, when Anglo Rhodesia Investment Co Ltd
were promoting the mine in 1917 they pointed out that they were encouraged
by the ammount of pyritic
matter that samples contained and that 'the sulphides are comming in earlier
than we anticipated' in a note they point out that sulphuric acid is a
bye-product (they do not say of what). Is it possible to economically
produce sulphuric adic from sulphide copper ores?
With reference to Bewdley could the presence of boat loads which included
copperas passing up and down various parts of the Severn have had any
relevance?
