The distinct initial 187 Os/ 188 Os compositions (Os i) of different pyrite types (colloform Os i = 1.35 and euhedral grains Os i = 0.79), coupled with the pyrite trace-element abundance, indicate that the Os, and by inference other metals (e.g., Cu, Ag, Au), was sourced from a Cretaceous magmatic-hydrothermal system (Os i = 0.74) and Late ...

Iron oxide copper gold ore deposits - Wikipedia

Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% and 5% copper, with gold contents ranging ...

STS Sedov - Wikipedia

STS Sedov (Russian: Седов), formerly Magdalene Vinnen II (1921–1936) and Kommodore Johnsen (–1948), is a four-masted steel barque that for almost 80 years was the largest traditional sailing ship in operation. Originally built as a German cargo ship, Sedov is today a sail training vessel, training cadets from the universities of Kaliningrad, Saint Petersburg and Astrakhan.

For example, the red symbol represents greater than 100 gpt Au-m and is calculated by multiplying the grade encountered by the thickness of the interval (i.e. “100 gram-meters” may represent 100 meters, grading one gram per ton Au, or 50 meters, averaging two grams per ton Au).

Contents of Au and Ag are up to ~1 and 10 ppm, respectively, with maximum concentrations that can rise up to ~800 ppm Au and ~300 ppm Ag due to the presence of submicron-sized inclusions. The high Co/Ni ratios of pyrite from Los Colorados are consistent with a magmatic-hydrothermal origin associated with a greater mafic affinity, compared to ...

Lime use and functionality in sulphide mineral flotation ...

The use of lime for pH control is critical to the process. At Newcrest Telfer Cu-Au mine (Australia), sequential flotation is used, in which pyrite is depressed first (by using lime and cyanide), and re-activated (with CuSO 4) prior to a second flotation stage (Benson et al., 2007). This is due to the unique copper-gold orebody at Telfer, which ...
