银—铋—镍—钴—砷(铀)五元素矿石主要产于德国的Joahanngeorgenstadt等一些地区,其他产地有匈牙利、瑞士、加拿大、美国、南非、墨西哥、法国等地。其中以加拿大安大略省的科博尔特—古甘达(Cobalt—Gowganda)地区最著名,研究得也比较详细。该矿床于十九世纪发现,含Ag从20(地表)到685(地下)g/t,平均130—230g/t。地表矿脉最富的矿石含自然银块体重达726kg,是北美最富的矿石。矿
Silver - bismuth - nickel - cobalt - arsenic (uranium) five elements of ore mainly produced in Germany Joahanngeorgenstadt and some other regions, other origin Hungary, Switzerland, Canada, the United States, South Africa, Mexico, France and other places. Among them, the Cobalt-Gowganda region of Ontario, Canada is best known and studied in more detail. The deposit was found in the nineteenth century and contained Ag ranging from 20 (surface) to 685 (subsurface) g / t with an average of 130-230 g / t. The richest surface ore veins containing natural silver block weighs 726kg, is North America’s richest ore. mine
