The International Mercury Cartel, 1928–1954: Controlling Global Supply
Published online by Cambridge University Press: 08 July 2015
Abstract
This article describes the features of the international mercury market during the first half of the twentieth century. It analyzes the various market agreements made, their effectiveness, and their consequences. The period studied is little understood, although it was one in which mercury production greatly increased. It was also one that saw persistent efforts at market manipulation, owing to a series of agreements between Spanish and Italian producers that proved very effective until the arrival of shipments of mercury produced by Soviet bloc members and by some developing countries.

8 Although the mercury figures are universal, there is a slight deviation with North American production, where flasks are marginally smaller. Specifically, U.S. flasks weighed 76 pounds while Spanish ones were 34.5 kilograms, equivalent to 76.0582 pounds (75 Spanish pounds).

In 1974, Monte Amiata mining activities were concentrated in a new state-owned company controlling all the mercury mines of the Amiata region. Finmeccanica, the Italian state holding for the mechanical and defense sector, acquired its real estate and financial assets, formally acquiring Monte Amita, when the company had already transferred its mines to the state; “Venta del mercurio de las minas de Almadén,” 1 Feb. 1930, b. 2, file 3080, SMA, AHN.

31 Finally, as guaranteed, Roura & Forgas was to deposit $150,000 in a leading bank, agreed upon with ME, and would allow the cartel to have a delegate in its offices to supervise the whole process (meeting of 20 Nov. 1931, ME managing committee minutes, vol. 3, R-15/515, AFA).

53 In August 1942 an offer from Japan to purchase 20,000 flasks had to be rejected because half the payment was offered in gold, with no guarantee that it could be delivered (meeting of 4 Sept. 1942, ME Spanish group minutes, vol. 6, R-15/527, AFA).
54 A good part of the increase in Spanish production figures was due to the use of forced labor in the Almadén mines (Angel Hernández, Los esclavos del rey [Almadén, 2010], 364–70).

The situation probably also was influenced by the fact that the Allies found 45,000 to 50,000 flasks in Germany when they occupied the country in 1945, but it is not known in what proportion the United States and United Kingdom split this quantity of flasks.

The U.S. decision probably was linked to the perspective that the Italian government was ready to include some deliveries of flasks to the Soviet Union in the framework of war reparations (Segreto, Monte Amiata, 163).
