Paper, 'Further contributions to the metallurgy of bismuth' by Edward Matthey

Description

Matthey writes: 'In the paper upon this interesting metal, which I had the honour of bringing under the notice of the Royal Society in February last [see PP/10/12], I referred to the difficulties with which the treatment of bismuth is surrounded when associated with other metals—by any very rapid or comprehensive process. During the conduct of my operations in the reduction of bismuth from its ores, and its subsequent refining, I have frequently found this metal to contain a small proportion of copper, an element most detrimental even in small traces, and hitherto I believe, only eliminated by a wet process, costly in practice and tedious in operation. It is necessary by such method to dissolve up the whole of the alloy and precipitate the bismuth in the usual manner—a bulky operation, and one requiring a considerable amount of time.'
