|Title||Paper, 'Further contributions to the metallurgy of bismuth' by Edward Matthey|
|Creator||Matthey; Edward (1836-1918); British chemist|
|Description||Matthey writes: 'In October, 1887, I read a paper before the Royal Society [see PP/11/8] upon a new method which I incidentally discovered while working with a view to separate copper from bismuth, by fusion with bismuth sulphide. I stated in this paper that bismuth “frequently contains a small proportion of copper, an element most detrimental even in small traces, and hitherto 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. It became therefore advisable, in order to treat cupriferous bismuth rapidly and upon a commercial scale, to effect this separation, if possible, by means of a dry process.”'|
