Historically very few mines in Britain produced antimony concentrates
and they appear to have been confined to Cornwall, Cumbria and parts
of Scotland. Stibnite, the antimony sulphide, was one (perhaps the
major) ore source but there also appears to have been significant
amounts of Jamesonite mined.
Jamesonite was a lead/antimony sulphide and I would be interested to
know what processes were in place to separate the lead and antimony
components of mixed sulphide ores such as Jamestonite before the
advent of froth flotation. There is plenty of information of
preparing single sulphide ores such as Stibnite - but how were mixed
sulphides such Jamesonite treated?
