21 kilometres north of Stewart (Figure 2-IZ-l), on the east The Silbak Premier mine is in northwest British Columbia, side of the Salmon River Valley. The original discovery of a that from 1918 to 1953 produced 4.3 million tonnes of ore high-grade vein in 1910 culminated in an underground mine grading 14.6 grams gold and 304 grams silver per tonne from sulphide-bearing stockworkveins and brecci...

The SearchMap software encourages users to incorporate experience and intuition into decisions that involve multiple layers of map information. Users define search configurations, search distances, and interlayer weights, and they “learn” from visual images, iterating search parameters until satisfied with the result. Successive sets of parameters record the thought paths of the user. In a gold...

Statistically reconstructed geochemical data on the main and additional elements in different types of rocks, ores minerals Kyzylkum gold mine. Based research, editing project problems with modern analytical methods (ISP-MS, atomic absorption, etc.). The results statistical processing materials content ores, near-ore space showed that they can serve as basis for creating geological genetic mode...

Abstract The arsenic-bearing gold ore in Anhui, China is an extremely refractory ore, and the cyanide leaching rate of concentrate only 30%. mineralogical factors low were discussed by process analysis. results demonstrate that contains 20.30 g/t gold, 3.39% arsenic, 29.80% sulfur, 4.10% iron. Gold exists occurrence states metallic mineral-wrapped gangue fissure which account for 64.90%, 8.31%,...

The Mouteh refractory pyrite concentrates at pulp densities of 1.5%, 3%, 4.5% and 6% were treated, using Thiobacillus ferrooxidans DSM 581 and the same bacteria adapted on the Mouteh pyritic concentrate. Compared with a non-adapted culture, use of an adapted inoculum of T. ferrooxidans increased bioleaching rate of iron by a factor of 1.940, 2.011, 1.859 and 1.559 for pulp densities 1.5%, 3%, 4...

Surface geological and geochemical mapping have been key technical contributors to many gold discoveries over the past 25 years. However, in the last ten years there has been a growing emphasis on using geophysical techniques to compliment them in covered terrains. As the search for gold deposits under covered areas expands, there will be increasing emphasis on integrating the geoscientific dis...
