Silver Ore

Silver processing, preparation of the ore for use in various products.. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen.The lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3000 ...

Flotation of Silver Bearing Minerals from Sulfide Ores

The ore minerals of this small, but rich, deposit were mainly chlorargyrite (silver chloride), acanthite (silver sulfide), argentiferous galena (silver-bearing lead sulfide), and native silver. The biggest producer, the Breman Mine, yielded $1 million in silver in just four years. By 1900, silver production at Chloride Flats had topped $20 million.

Silver, iron, and zinc sulfides have been used to precipitate mercury from gold cyanide solutions (~) but require slurry fiLtration before sulfide addition to re­ claim excess reagents. Silver sulfide addition would tie up considerable sil­ ver, and silver sulfide excess would have to be recovered. Iron sulfide is un­

Other turnkey modular systems for pre-concentrating coarse ...

Sulfide Ores

Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching. Uses. Silver has been used for thousands of years for jewelry and decorative items of all types. Likewise, it has been used for silverware.

Froth Flotation Method

Silver is considered to be a soft, malleable metal available with a characteristic sheen. It has the highest electrical and thermal conductivities of all metals. It is usually found uncombined, or in the arsenide or sulfide ores from which it can be recovered as a cyanide complex which is consequently reduced to the metal, in aqueous solution ...

The Source of Silver

Feb 11, 2020· The Lynne deposit was discovered in 1990 by Noranda Exploration and is located on forestry land owned by Oneida County within the town of Lynne. It is primarily a zinc sulfide ore with significant lead and silver and minor amounts of gold and copper. The deposit is estimated to be approximately 5.6 million tons recoverable by open pit mining.

Precious metals can be found in ore deposits along with sulfur, and are known as sulfides. Cadmium, cobalt, copper, lead, molybdenum, nickel, silver, zinc, and gold and platinum group metals can be found in sulfide forms. These concentrated ore deposits are considered low grade because of the economic costs associated ...

The ores in these veins consisted mostly of non-mineralized, massive, white quartz interspersed with layers of heavily mineralized, dark quartz, the latter rich in acanthite, argentiferous galena, silver sulfide, and native silver.

Recovery of Silver, Gold, and Lead From a Complex Sulfide ...

The need for a new process to treat Broken Hill ore arose from the depletion of the secondary oxide ore that overlay the major sulfide mineralization. Natural oxidation to form the secondary zone had resulted in a concentration of silver and lead, and ore from this section of the ore-body could be smelted directly.


Sulfide precious metal ores are difficult to amalgamate using mercury, due to the complex iron-sulfur-gold and other metals present, which do not allow the gold to come into contact with the mercury. It is not uncommon for only 20% to 30% recovery of gold and silver by mercury amalgamation from sulfide ores.

Mercury Amalgamation

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

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.
