2021-12-1 · 1. Introduction. Gold and silver are commodities which occur in many types of hydrothermal ore deposits and geological contexts (Zhu et al., 2011).The mineralogy of gold and silver is variable within and across these different deposit types, with both noble metals known to occur as native metals and alloys, and in stoichiometric amounts in, e.g., sulfides, sulfosalts,

The Waihi Epithermal Gold-Silver-Base Metal Sulfide

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

Deposition of gold and silver in high grade ore shoots is associated with the process of fluid boiling. Deposition of quartz and gangue minerals from hydrothermal fluids heals fractures in host rocks. This results in over-pressured fluids which ...

Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.

Where silver is present in the sulfide ore, some of the silver may form the sulfate salt and be recovered together with the base metals such as copper. In the fluidized-bed reactor, the base metal sulfate is usually produced at temperatures in the range from 100° to 650° C., and preferably 200° to 600° C.

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.

2017-3-4 · The ore has a 5 to 10 percent sulfide content, so I expect about 10 to 20 pounds of sulfide concentrate. Dealing with 10 to 20 pounds is a lot easier than 200 pounds. There will be some loss of values in this operation - but I accept this because although the method is less than optimal, it's the best I can put together.

We consider mineral assemblages and mineralogical and geochemical peculiarities of hypogene gold from the Khaak-Sair multistage low-sulfide gold-quartz ore occurrence in listwänites. Three productive substages of Au-and Ag-mineral formation have been recognized on the basis of mineralogical studies: gold–sulfosalt–sulfide–quartz, gold ...

sulfide vs oxide gold ores - stfrancishome.ch

The Mantoverde iron oxide-copper-gold (IOCG) deposit, Chile, contains hundreds of millions of tonnes (Mt) of mineable iron oxide and copper sulfide ore. While there is an agreement that mineralization at Mantoverde was caused by hydrothermal fluid (s), there is a lack of consensus for the role (s) that non-magmatic vs. magmatic fluid (s) played ...

Pacific Quartz Mine (MRDS #10310663) AU

A number of ore shoots several hundred feet long and as wide as 12 feet were developed. The ore yielded $6-$18 per ton in gold, and contained considerable amounts of pyrite, arsenopyrite, and silver (Clark and Carlson, 1956). Sulfide concentrates made up 0.5 percent of the ore and assayed $85 per ton in gold and $2 per ton in silver (Logan, 1934).

Gold ore is obtained from a variety of ores. Most people think a lot of gold comes from nuggets. But the truth is that very little comes from actual gold nuggets. Practically all newly mined gold comes from ores and gold quartz mined from the natural rock ore that carries gold in tiny, even microscopic particles.
