Souvenirs from Copper Refineries |
| |
Copper refineries
convert concentrated ore with a high mineral content to pure copper in forms that can be
bundled in 25 ton lots and sent anywhere for trade or use in the production
of copper and copper alloy products. In good times they may make more money
than the foundries and fabricators so can afford to produce interesting
items as promotional gifts. All refineries work
to similar agreed standards of purity to satisfy the trading requirements of
the London and American Metal Exchanges. Nevertheless they have a great
pride in the quality and reputation of their own brand and the extent to
which its purity is better than standard.
Refineries have their own three-letter
brand abbreviations to identity their copper and these are often
incorporated in their gifts. It has to be said though that unless you
know and admire the products normally made, you might not think that
refinery souvenirs are the best choice for mantelpiece display.
However, they were some of the most difficult to make when refineries used
traditional extraction processes and are much less common now that
production methods have become more integrated and environmentally friendly
so should be treasured. |

1830 Bingham Canyon
souvenir pin tray showing typical scenes including the mine, a loader, an
electric mine locomotive, two miners with an early pneumatic drill and the
old town. Interestingly, the tray looks as though it is made as an
electroform, a similar process to the electrolytic refining method used to
produce their cathodes. However a gentle scrape reveals that it is copper
plated zinc sheet. Some of these are marked on the back 'Made in Japan'.
Height 115mm (4 1/2"). Weight 85g. |

1395 Two copper
refinery ashtrays that come from the Morenci, Arizona smelter that was
closed many years ago. Originally these were made and given to special
guests as gifts. The red colour is typical of the oxide on cast copper. The
heart shape is 70mm (2¾") square and the Arizona state shape says ‘Morenci ARIZ’ in the bottom. It measures
75 x 83mm (3 x 3¼"). |

3561 A copper tray
found in a spoil dump next to a mine at Jerome, Arizona. Most of the mines
in Arizona tried casting souvenirs at some time. Some had no embossing but
this reads ‘UVX’, the original name for the United Verde Extension and
Jerome Arizona mine, before it was renamed ‘Jerome Arizona’. The mine was
established in 1883 and closed in 1935. This was very crudely made and is a
good example of just how gassy a copper casting can be! It is not
surprising that it was scrapped. It measures, 150 x 60 x 20mm (3 x 2¼ x
¾"). The inside is dark, and the back is the red colour of cast copper.
Weight 130g (4.7oz). |

3680 Anaconda The
American Brass Co paperweight in the form of the company arrow logo on a
base. The item is an excellent quality two-part casting made at the
refinery in high conductivity copper and shows no signs of porosity or other
significant casting defects. The surface finish is as-cast copper oxide.
On the base is the lettering 'From mine to Consumer' and to it riveted the
arrow head and part shaft, lettered 'Anaconda' on both sides.

Anaconda
Company Arrowhead Paperweight. Anaconda Brass started as J.F. Brown’s
Copper & Brass Rolling Mills, in 1919, located on Birmingham Street, New
Toronto, Ontario. Anaconda acquired the mills soon after in 1922. In its
last few years of operations, it was Arrowhead Metals. The plant closed its
doors for good in 1989.Anaconda
Copper Mining Company (ACM, until 1915 known as the Amalgamated Copper
Mining Company), one of the largest trusts of the early 20th century, owned
all the mines on Butte Hill, Montana, USA. In 1922 they bought the
American Brass Company. The Anaconda Company was purchased by
Atlantic Richfield Company (ARCO) on January 12th 1977.

3758 A strictly
functional ashtray cast at Enfield Copper Refiners in high conductivity
copper and still showing the as-cast purple oxide finish. These were
specially cast as souvenirs for guests at an open day in 1969. The
underside is covered with a protective green baize. With a wall thickness
around 5mm (5/16”), it is not surprising that it weighs a heafty 860g (1lb
14oz). |

6902 A sample of electrolytically refined copper neatly cropped from a cathode of 99.95+%
pure metal. The ore was mined at Mufulera and smelted at Ndola Refinery
owned by the Rhodesian Selection Trust (RST International Metals) in what
was then Northern Rhodesia c1965. The nodules were entirely typical at that
time but process improvements have resulted in smoother cathodes being
produced now. Length 160mm (6¼") Weight 1kg, cut from a cathode
of 100kg. |

6903 Miniature anode
cast as a gift for special visitors to Ndola Copper Refinery in Zambia
c1981. From the fire refining stage of the purification of copper anodes
are cast in roughly square shape with ears at two corners to enable them to
be hung between the cathodes in an electrolytic refining tank. This has a
width, without the ears of 73mm (2⅞") and a weight of 600g whereas
production anodes would be about 1,000mm square and weigh about 100kg. |

7069 When the
fire-refining of copper was the main process it was usual to cast it to the
form of wirebars for subsequent hot rolling and cold drawing to wire. This
souvenir was made for invited guests at the commissioning of the new
Southwire continuous copper wire rod plant on the 17th October 1974 at
Enfield Rolling Mills, Middlesex. Copper cathodes were then melted in a
shaft furnace and continuously poured to give the smaller cast shape shown
which was then immediately rolled on to the 6mm diameter size of the top
coil. The base is marked on the sides 'First SCR Coil’.
Below right is a section from a wirebar and a miniature
souvenir gift made for a previous occasion. Wirebars could be 60-225kg in
weight, typically 100-125kg and could only be rolled into rod of that size
pieceweight before joining for subsequent wiredrawing. The continuous
process avoided these joints that gave potential breaks later. |

9149 A ‘Black
Museum' item from Enfield Copper Refiners, Middlesex. This is a section of
a sample taken from a 180ton open hearth refinery furnace before it was
ready for pouring. The 'gassiness' of the copper showed that it needed
further 'poling' by having the melt stirred with long poles made of damp,
green wood that bubbled fiercely under the copper and removed excess
hydrogen. Normally the refinery foreman would not have needed to section
the sample - just feel the weight in his hand to check that it was solid
copper. This type of souvenir was invaluable as an example that is better
than a thousand words. With the demise of the process and when generations
move on in the industry it unfortunately tends to loose perceived value
completely and may end up being recycled with other scrap instead of
preserved with its history. Length 125mm (5”), diameter 44mm (1 ¾”). |

ANACONDA
COMPANY COPPER PAPERWEIGHT This is a round copper paperweight from the
Anaconda Company. It has BUTTE stamped on the top of it. Base diameter
approx. 2"; about 1" high. In 1899, Marcus Daly merged with Rockefeller's
Standard Oil Company to create the Amalgamated Copper Mining Co. In 1910,
the company changed its name to the Anaconda Copper Mining Company, after it
bought up many smaller companies. The original mines at Butte, Montana are
now a pit over a mile long, nearly a mile wide and
1800 feet deep. Mining ceased
here in 1982 but the company owned many others world wide. Since 1977 it
has been a subsidiary of Atlantic Richfield Company (ARCO). |

Utah Copper
Co. promotional paper weight in the shape of an ingot. Length 74mm (c3").
Utah version began on June 4, 1903 when the original Utah Copper Company (UCC)
was created to mine and process low grade copper ore found in a mountain in
Bingham Canyon, about 25 miles southwest of Salt Lake City. Steam shovels
began working on the mountain in 1906. For the next 100 years, shovels,
trains and trucks converted that mountain into the world famous Bingham
Canyon Mine, a huge open pit copper mine that is more than three-quarters of
a mile deep and more than 2 3/4 miles wide across the top and still
growing. In 1915, Kennecott Mines became Kennecott Copper Corporation,
which purchased a 25 percent interest in the Utah Copper Company and
acquired all assets and property in 1936 forming Kennecott Utah Copper (KUC).
In 1947, Utah Copper Company was dissolved and became the Utah Copper
Division of Kennecott Copper Corporation. In 1981, Standard Oil of Ohio (SOHIO)
purchased Kennecott, and in 1987 British Petroleum bought SOHIO’s interests.
In 1989, RTZ Corporation, now known as Rio Tinto, became the owner of
Kennecott Utah Copper Corporation. |

4285 Copper ashtray
from IMI Refiners, December 1985 575g 'This copper ashtray is a memento of
your visit to IMI Refiners. It has been made from a slice of 92mm diameter DHP
(deoxidised high-phosphorus) copper billet cast on our horizontal casting machine. The cast surface
is typical of our horizontal product showing the witness of the oscillation
of the mould. The underside of the ashtray has been etched to show the cast
structure and the centrality of freezing.' |

7032 Promotional
ash tray made for British Copper Manufacturers Ltd. 140mm dia. The company
was formed in 1924 by the amalgamation of the two major copper smelting
firms in Swansea, Messrs. Vivian and Sons; and Messrs. Williams Foster and
Company and Pascoe Grenfell and Sons Limited. Messrs Vivian and Sons had
been founded by John Vivian, a Cornish mine owner in the early nineteenth
century. Messrs. Williams Foster and Company and Pascoe Grenfell and Sons
Limited had been formed out of two Swansea firms, Messrs. Pascoe Grenfell
and Sons and Messrs. Williams, Foster and Company in c1892. BCM was taken
over in 1927 by ICI Ltd and Yorkshire Metals to form Yorkshire Imperial
Metals Ltd. which included other factories in Yorkshire and Lancashire. |
