A similar case was noticed by Mactear in South America, where a limonite ore which only yielded from 35 to 40 per cent, of its gold when treated in Huntington pans, was made to yield between 85 and 90 per cent, by merely subjecting it to a dehydrating calcination before amalgamating it.

Pyrite, chalcopyrite, and gold occur in quartz veins in granitic rocks and as scattered and disseminated impregnations in shear zones of the highly altered metavolcanics in the Hamash area, Southeastern Desert, Egypt. The minerals are associated in part with pyrrhotite, digenite, tetrahedrite, chalcocite, bornite, and covellite. Pyrite occurs in two forms: (1) idio to hypidiomorphic coarse ...
The gold veins of Nova Scotia are in rocks of Cambrian (or possibly preCambrian) age, and are therefore younger than those rocks. The veins of the Kirkland Lake gold area in Northern Ontario, are associated with igneous rocks that intrude conglomerate and other sedimentary rocks, preCambrian in age; this fixes a limit for the age of the veins.
May 22, 2018· Limonite is mainly derived from weathering of Fe sulfide, ironbearing carbonate, or silicate minerals. The weathering of Fe sulfide or carbonate minerals to yield limonite from the Tongling mineralization cluster has been studied extensively. Knowledge of the mineralogical and geochemical characteristics of the limonite from weathering of Febearing silicate minerals is still incomplete, .

Heavy mineral assemblages were analyzed for native gold content, and the results suggested high native gold content in the illitizationpyritization belt, followed by quartzpyritization belt, which was consistent with the strong association of limonite and gold mineralization, thus the two belts shall be prioritized for gold prospecting in the ...
The problem is that gold occurs in many types of deposits, and what indicators work great for one type of deposit don''t always work well for another. As an example, in some places the presence of vein quartz on the ground is a valuable indicator, yet I have been in places where there is so much vein quartz everywhere that is worthless as an ...
