Apr 18, 2016· In Gold Flowsheet No. 1 the ore is ground in water to such a size as to free the minerals sufficiently to produce a tailing by flotation low enough in value that it may be discarded. Here a Mineral Jig is used in the Ball Mill Classifier circuit. This recovers coarse and fine free gold preventing any build-up in the circuits especially in the grinding circuit. …

DetailsApr 01, 2021· The major chemical components of the sulfide refractory gold ore and pyrite are shown in Table 2. The sulfide refractory gold ore (SRGO) contains 30.34% Fe, 22.23% S, 11.19% As, 3.24% Al and 60.25 g/t Au. The total content of Fe, As and S is up to 63% of the sulfide refractory gold ore. The pyrite contains 43.36% Fe and 41.26% S.
DetailsMar 01, 2002· The decrease in salinity following dilution favored the transport of gold, silver, and copper as hydrosulfide complexes and led to the deposition of the electrum-bearing Zn-Pb-Fe-Cu-Ag sulfide assemblage over a temperature range of 260° to less than 190°C at paleodepths of 500 to less than 250 m.
DetailsApr 14, 2014· Put your silver and low sulphide content in the bottom of a clay crucible and cover it with about 3 times weight of borax then let it go in your kiln till it hits 2000 degrees and give it some time to react. Pour your mix into a cone mold let it cool then break off the borax on top of your prill. Now you should have a prill that is a brittle ...
DetailsDec 20, 2020· Location. Pacific NW. Dec 20, 2020. #3. Much depends on the ore or how the gold was formed in the ore. gold from volcanic action is different from gold formed by fault zones and shifting of these faults under each other, more basically if the gold is free-milling and can be concentrated by gravity methods, or microscopic gold locked up in the ...

DetailsFeb 12, 2008· The ore was primarily quartz, with streaks of iron pyrite, silver, gold and galena. The ore was crushed fine in a ball mill, then run with cyanide and bromine. Extraction was well over 99%, even without eliminating the sulfides. I tried a similar process with the pyrite (mentioned above), but got almost no recovery.
DetailsJan 01, 2007· A total of 285 samples of ores, quartz veins, ... Gold and silver in massive sulphide ores occur mainly as electrum grains 1 to 20 μm in size. Microprobe analyses of five grains give Au contents in the range 52.34 to 70.28 wt.% with a mean of 61.47 wt.% (Liu et al., 1994). Most of the electrum occurs as inclusions in chalcopyrite, pyrite and ...
DetailsOct 20, 2017· A procedure was developed for recovering gold, silver, cobalt, copper, and zinc from a massive sulfide ore by a hydro-metallurgical process. The procedure consists of (1) oxygen pressure leaching; (2) iron, arsenic, and copper removal from the leach solution by precipitation; (3) selective extraction of cobalt and zinc from solution; (4) electro …
DetailsMay 11, 2017· For example, the assay value of the fine pulp having been found to be $20.00, and the proportion of coarse gold to each assay ton of pulp 1 milligram or $20.67, then the total value per ton of ore in gold would be equal to $20.00 plus $20.67 or $40.67. Silver values fluctuate and may be figured at the ruling market price per ounce.
