These pictures are of the same rock just different sections and were assayed to have gold content in them. The gold was only in the 500 ppb range but you can expect that the gold was probably trapped inside the matrix of the chalcopyrite and the Arsenopyrite.

Arsenopyrite is an iron arsenic sulfide (FeAsS). It is a hard (Mohs 5.5-6) metallic, opaque, steel grey to silver white mineral with a relatively high specific gravity of 6.1.When dissolved in nitric acid, it releases elemental sulfur.When arsenopyrite is heated, it produces poisonous sulfur and arsenic fumes which can be fatal if inhaled in large quantities.

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...

The J-M Reef ore body in Montana contains mostly copper and nickel, with low platinum content as a byproduct. Gravel deposits in Alberta, Canada, provide a placer source for platinum in certain rivers, where it coincides with gold and other minerals. Platinum flakes can be recovered through gravel washings, shaking tables and other methods. Generally, platinum grains require microscopy for ...

Arsenopyrite, or mispickel, is the most important ore of arsenic. It is found in crystals and in compact and granular masses. It is a silver-white metallic mineral resembling very closely cobaltite in its general appearance. In many specimens the iron is replaced in part by cobalt, nickel or manganese. Sometimes the cobalt is present in such large quantity that the mineral is smelted as an ore ...

One of the more common classes of ores containing gold is when gold is associated with pyrite, pyrrhotite, and arsenopyrite. This is the area of gold recovery that has probably received the most research and plant optimization support especially in light of the long history of South African industrial practice. From a reagent viewpoint, charged water soluble collectors such as xanthates ...

The salinity and temperature of ore-forming fluids have wide ranges. Salinities of some ore-forming fluids are lower than sea water, whereas those in fluids forming porphyry deposits can reach 80 wt.% NaCl (Heinrich, 2007).The salinity and temperature of most hydrothermal fluid decrease during the late-stages of ore formation, suggesting either the attenuation of heat and fluid source or the ...

Roasting Arsenopyrite Ore for Gold. The roasting of ores containing arsenopyrite presents greater difficulties than straight pyritic ores mainly because of the tendency toward the formation of insoluble arsenites and arsenates, which have a detrimental effect on gold recovery.
