Japan Gold - Hakuryu Project

Ore minerals are mainly electrum and argentite with polybasite, pyrargyrite and pyrite. Minor chalcopyrite, sphalerite and galena are also present. The gold-silver ratios range from 1:4-6, which are the lowest in the Konomai group deposits 2. Plan view of the vein array which defines the Motoyama main deposit2.

“Japan, the Land of Gold.” How True Is the Old Legend ...

15/06/2008  Today, gold is mined in Japan only at Hishikari in Kagoshima in southern Kyushu. Hishikari is now one of the best gold mines in the world. The average grade is 40 grams of gold to one ton of ore. A profit can be made at 2 grams per ton, so the gold at Hishikari was certainly a major find. Since digging began in 1985, the mine has produced seven to ten tons of gold per year—165 tons over the ...

Mineral Processing. 5. Milling. Crushing typically takes Run-of-Mine (ROM) ore down to particle sizes ranging from 6mm to 25mm, depending on the type of processes to follow. Crushed ore is fed into Mills in which the ore is mixed with water and may be ground down to a particle size, in the case of gold and copper, of about 75 microns (0.075mm).
