Silver Mining Process . Silver is mined using a number of processes. One of the most common processes of extracting silver metal for the ore is the heap leach or cyanide process. The process is most popular with many miners because it is low cost, especially when processing …


Platinum Processes & Uses. A solid platinum nugget. Image from popsci.com. Nuggets or grains of pure platinum can be found in nature, but more frequently, platinum is found alloyed with other metals, such as iron, copper, gold, nickel, and the other PGMs.The size of platinum grains or nuggets varies from small granules to pebbles weighing up to 20 pounds (9 kg) or more.


A leaching process for platinum contained in a magnetite ore was studied, as an alternative process to cyanidation and aqua regia digestion. The proposed process employs concentrated chloride solutions and ozone gas injection during the entire leaching process. The effect of pH, chloride concentration and temperature was analyzed.


A nugget of gold, about 0.7 cm in length, was recov-ered in a Knelson concentrator at the iron ore plant. The nugget is partially coated by a black to reddish brown material, which gives the characteristic dark-colored appearance to the ouro preto (Fig. 1a). Microscopic in-vestigation of a polished cross-section of the nugget


A nugget of palladian gold, obtained from a specularite-rich auriferous vein ('jacutinga') of the Gongo Soco iron ore mine, Quadrilatero Ferrifero, Minas Gerais, allows the definition of a paragenetic sequence of native palladium formation.


The ore is concentrated mainly - Pd 68.9%, Ir 8.1%, Ag 6.9%, Au 5.7 %. Would a simple mixture of Hydrochloric acid and Hydrogen peroxide ( 20:3 ) dissolve just the Palladium from the ore or will it dissolve all? or is there a better way? My knowledge on refining is very limited. Any advice would be great. Henry Miller hobbyist - Canguu, Bali ...

The platinum-palladium mineralization was associated with the sulfides which made up about 1 pct of the rock. Microscopic examination of screened fractions of crushed ore showed that most of the sulfides could be liberated at 200 mesh. The Bond Index value for grinding the ore to minus 200 mesh was 16 kW·h/ton.

PALLADIUM : More than 80% of the palladium metal mining is located at the Stillwater Mine is automated. Mechanized mining expenditures are in the region of 40% less than non-mechanized conventional mining techniques. The mainstream of ore created at the Stillwater Mine is resultant from mechanized access ramp and fill mining.

Palladium Mining When most people think about mining, they probably think about a guy in a mine with a pickaxe hammering away all day for a few nuggets of gold. Although this is still a useful process for many parts of the world, it simply doesn’t work for difficult to extract minerals such as palladium.


In Stillwater, Montana, pgm is extracted from the J-M Reef. 80% of their platinum and palladium-rich ore is mined using a mechanized ramp and fill method, much like the LHD method in South Africa. In Russia, significant amounts of platinum have been produced from mine sites in far eastern Russia and the Norilsk-Talnakh mine located within the ...

Because the ore is sulfidic in nature, it was concentrated by froth flotation. A 45 kg/h process development unit (PDU) was constructed and 85 to 95% of the platinum and palladium were recovered from the ore by using mercaptobenzothiazole or sodium isobutyl xanthate as collectors.


I recently thought i found gold, i had it XRF scanned and it returned 80-90% Fe and 10-20% Rh (avg from 5 rocks) it also had a very small amount of palladium. I did not know what RH was so i aid damn and took my rocks home, then a dy later i read how valuable Rh is and what Rh is. And i...


markings like leafy or triangle or scales is the best way to detect genuine palladium rhodium or white gold from ores..


The first step in extracting rhodium from the ore is precipitating precious metals such as gold, silver, palladium, and platinum. The remaining ore is treated with sodium bisulfate NaHSO 4 and melted, resulting in rhodium (III) sulfate, Rh 2 (SO 4) 3.


In Canada, platinum and palladium are obtained from the mattes obtained by smelting the nickel-copper ore of Sudbury, in Ontario. The high-grade mattes contain from 0.2 to 0.5 oz. of platinum metals per ton. The platinum occurs in the Sudbury copper-nickel ore as sperrylite, embedded in chalcopyrite.


Palladium Ore is an orange-colored Hardmode ore which can replace Cobalt in a given world. It appears similar to Copper Ore but is slightly more saturated.. Like other Hardmode ores, Palladium is generated upon destruction of an Altar with a Pwnhammer, it is immune to all types of explosions and requires at least a Molten Pickaxe to mine. It can also be obtained from Crates.
