The different steps involved in extraction of silver are: a. Ore . The Silver Extraction Process athens123. The Silver Extraction Process. The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead.

silver from sulfide ores with FeC13 was patented by Hey in 1922 (6). Considera ble work was completed by-Wong (7) to re cover lead from a galena concentrate with a combined FeC13-NaCl leach solution. Because both lead and silver were solu bilized, silver recovery from high-silver ore would be difficult. Similar methods
All silver ores need to be fluxed for smelting.6 In Pliny's day, when almost all the ore smelted was high-grade, the addition of lead or lead ore (galena, PbS) was sufficient for fluxing (book XXXIII, sec. XXXI). By the time that Biringuccio and Agricola are writing in the 16th century, the art of fluxing has advanced in complexity but not in ...
The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.
CIP plant, a series of small adsorption tanks is installed after the leach plant and the leaching reaction is essentially complete before adsorption starts. CIL is advantageous when the leaching kinetics are fast and when the ore contains mineral phases that are able to re-adsorb the gold cyanide in competition with activated carbon (preg-robbing).
In the pressure leaching process, sulphide ores and concentrates are leached in autoclaves at temperatures of 200 to 220°C and a pressure of about 3000 kPa (Schlesinger et al., 2011). An oxidizing agent, usually oxygen, is required to oxidize sulphide ions to sulphate ions. The oxidation of sulphur to sulphate is exothermic; consequently, a

Frequently, we use nonselective bulk sulphide flotation ... silver-lead-zinc-pyrite, silver from sulfosalts, enargite-pyrite, lead zinc-pyrrhotite, nickel- ... and plant design. We analyse new and existing ore bodies and flowsheets to optimise grade and recovery ...
Flotation to separate the Lead Sulfide from the zinc Sulfide, and possibly separation of the Copper Sulfide. Silver will be retained with the Lead Sulfide. This will utilize floatation cells that involve mixing the Ore dust with water and the Chemical in order to cause only the desired element, whether Lead, Zinc or Copper, to float to the ...

In southern Africa, two x-ray sorters are used to pre-concentrate sulphide gold ore into two different grain size categories. While the input material has an average gold content of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%.
The problem under consideration is the design of a hundred-ton mill for treating silver ores by cyanidation... The Sulphur is partly combined as Sulphide and partly as the Iron Sulphates, FeSO₄ and Fe₂(SO₄)₃. To determine the best method of procedure, preliminary tests were run on lots of 100 pounds each, this being crushed in a ...

Subsequent to the treatment of the currently defined oxide gold and silver resources in Stage 1, the Plant will be upgraded to incorporate a sulphide flotation circuit capable of processing the Hayes Creek high-grade gold-silverzinc massive sulphide ores into two valuable product streams, a zinc concentrate and a precious metals concentrate ...
The plant design for froth flotation of sulfide ores depends on its component and ore floatability. After crushing grinding and gravity separation of sulfide ores, the froth flotation plant design is conducted under mineral testing and floatation reagent design. Application: With 20+Years experience of EPC service & Beneficiation Plant Design.
The ore extracted is transferred to the appropriate sulphide or oxide ore stockpiles for processing. Lyntek Engineers and Constructors was contracted in October 2004 to design and build two separate processing plants for treating sulphide and oxide ores. Both plants share the same crushing and conveying system.
Mar 19, 2018· Silver is an economically important component of many complex, massive sulfide ores, and often is produced as a byproduct during recovery of base metals from sulfide deposits. About two-thirds of the world's silver resources are contained in base-metal sulfide deposits (Reese, 1991). These ores are beneficiated almost exclusively by flotation.
processing for copper removal and cyanide recovery is used. In 2015, a flotation plant was added to treat the tailings from the agitation leach plant before the tails are sent to the tailings dam. This plant produces a copper sulphide flotation concentrate and also recovers some of the residual gold and silver …
The sulphide material processing facility consists of two equal circuits of a conventional SAG mill, two ball mills, a pebble crusher, HPGR, and a sulphide flotation plant producing lead and zinc concentrates with some gold and silver content.

Acanthite is the most important silver ore next to galena.Actually there is an argument to be made that acanthite could be the most important silver ore. Galena is a lead ore that often contains enough silver (usually about 1%) that when it is processed for its lead content the by-product silver supplies the majority of the world's needs. But most, if not all the silver in argentiferous galena ...
