56 THE METALLURGY OF ANTIMONY.
CHINA.*
From private information received by the author, the ore seems
to occur in veins of quartz. The low-grade ore carries more or less
gold and silver. (A and B.) The principal localities are Nanning,
Ssucheng, Taiping, and Hsilin districts, in Hunan province.
JAPAN.
According to K. Yamada, stibnite veins are found in the island of
Shikoku. They are, as a rule, thin, and occur in schists and other
palaeozoic rocks. The gangue is generally composed of quartz, and
sometimes of quartz and pyrite. (A.)
At Itshinokawa, the veins occur in sericite schist, having as gangue
materials quartz and a little calc-spar, banded with druses which
contain very large beautiful crystals. (A.) At the Nakase mine,
the stibnite is gold-bearing. (B.)
At Kano, in the southernmost part of the Hondo peninsula,
tho veins are 2 to 9 feet in width, and continue for a distance of
6000 feet, cutting through the crystalline schist mountains. (A.)
At Totsugawa, south of Kioto, the vein cuts through a quartzitio
and graphitic schist. (A.)
The remaining localities are Nara, Ehrme, Yamaguchi.
BORNEO.
In the northern part of Borneo (Sarawak) the antimony ore, sometimes
accompanied by pure arsenic and arsenic sulphide, occurs in
quartz veins, cutting through the limestone and the slate formations.
COOHIN-CHINA.
Stibnite has been found between Quan-Yuen and Moucai in Tonkin.
It has also been found in rounded stones or boulders of varying size,
which have a peculiarly smooth yellowish-brown surface, accumulated
in the beds of torrents.
ASIA MINOR.
Stibnite, with quartz as gangue, is found in the vicinity of
Smyrna.
