Pattinson Metallurgy.|ˈpætɪnsən|
[Name of Hugh Lee Pattinson (1796–1858), English metallurgical chemist, who patented the process in 1833 (Brit. Pat. 6497).]
Pattinson('s) process: a process formerly used for desilverizing and purifying lead (see quot. 1881).
1856W. A. Miller Elem. Chem. II. xvi. 994 (heading) Concentration of silver in lead by Pattinson's process. 1881Raymond Mining Gloss., Pattinson process, a process in which lead containing silver is passed through a series of melting-kettles, in each of which crystals of a poorer alloy are deposited, while the fluid bath, ladled from one kettle to the next, is proportionately richer in silver. 1912[see Parkes]. 1946Thorpe's Dict. Appl. Chem. (ed. 4) VII. 224/1 The value of the Pattinson process as a means of purifying lead is shown by the fact that lead to be used for white-lead making was frequently Pattinsonized, although the amount of silver present was too small to repay the cost of its recovery. 1964H. Hodges Artifacts vi. 93 This method of enriching a lead alloy is now known as Pattinson's process. |
