Before the war Spain imported annually 800 tons of antimony ore from
France, and over 100 tons of salts of antimony was exported annually to
Germany.
Asia.
_Borneo._--British Borneo was formerly a producer of considerable
importance, and much ore was exported between 1859 and 1894, mainly
to England. The deposits then remained idle until 1914, when 870 tons
of ore was exported; in 1915 the exports amounted to about 360 tons.
It is probable that no important output at peace-time prices is to
be expected, although the country is largely unexplored. The Borneo
company (British) seems to have been the principal if not the only
producer.
_China._--With all her vast mineral resources China has been able to
obtain an important position in the world’s markets with regard to but
few metals. Of these antimony is the most striking example, for since
1908 over 50 per cent. of the world’s total antimony production has
come from China. In 1913 the output was estimated to be the equivalent
of 10,800 tons of metallic antimony, that of the whole world being
about 20,000 tons. The Chinese industry being well-established, it
was able to respond rapidly to the great demand of the war. Exports
increased from 14,361 short tons of regulus and crude antimony,
and 4,795 tons of ore, in 1913, to 38,142 tons and 8,667 tons,
respectively, in 1917.
Antimony is found over widely scattered areas in the central and
southern provinces, but chiefly in the provinces of Hunan, Yunnan,
Kweichow and Kwangsi. In Hunan the deposits have been most extensively
exploited, probably 90 per cent. of the total production of China
coming from the region about Changsha, the center of the smelting
industry. Here, in the Hai-Keng-Shan district, in 1915 about 70
companies mined antimony along the outcrop of the deposits. The ore,
remarkable for its purity, occurs as pockets and bunches, mainly of
stibnite, in a flat bed of dolomitic limestone. Several local smelters
produce liquated sulphide, and the output of the district is about
1,000 tons monthly of crude antimony averaging about 70 per cent.
metallic antimony. All regulus manufacture is controlled by the Wah
Chang Co. In the Panshi district the ore occurs as fissure veins in
slates, shales, and quartzites. The output consists of about 400 tons
monthly of 30 per cent. ore, all of which is shipped to Wah Chang Co.
at Changsha for treatment.
The only district in Yunnan where antimony is dealt with commercially
is near Chihtsun on the Tongking-Yunnan Railroad. The Pao Hua Co.,
connected with the Wah Chang Co., owns a French-constructed plant and
produces high-grade regulus.
