Silver mineral resources reserves are widely distributed in the world, and silver is one of the most relative concentration mineral. NFLG can supply you silver production equipments such as jaw crusher , impactor crusher, cone crushers . Our silver processing equipments have exported to dozens of countries and regions in the world.
the main characteristic of silver resource in the world
1. Widely distributed resources, reserves the relative concentration of silver is the world’s most widely distributed mineral one, from land to Ocean (including silver metal ooze etc.) are available for development and utilization of the silver deposits. So far, almost 60 of the world in many countries and regions proven industrial silver deposits, but the reserves are relatively concentrated in the south, North America, Canada, the United States, especially Mexico, Peru and Bolivia and other countries, these countries account for world silver reserves and yield more than half.
2. Less common, independent silver, silver associated with the large amount of resources silver resources from other minerals is one of the greatest characteristics as the deposit, associated components, while the individual is given priority to with silver deposit less. The world bank resources of about 2 / 3 is the copper, lead, zinc, and tin, gold and other nonferrous and precious metal deposits, companion, 1 / 3 is give priority to with silver, known as independent silver deposits.
Silver Ore Concentrates
Silver concentrates are roasted and then leached with sulfuric acid to dissolve their Silver content, leaving a residue that contains lead, silver, and gold-along with 5 to 10 percent of the Silver content of the concentrates. This is processed by slag fuming, a process whereby the residue is melted to form a slag through which powdered coal or coke is blown along with air. The Silver is reduced to the metallic form and is vaporized from the slag, while the lead is converted to the metallic form and dissolves the silver and gold. This lead bullion is periodically collected and sent to lead refining, as described above.
Silver separating methods
Silver deposits as such are relatively rare and count for little in total world supply and output. Between 80 and 90 percent of the silver is extracted as a by-product from deposits of complex ores, mainly from lead-zinc (45 percent), copper (18 percent), and gold-silver (10 percent) ores. Between 10 and 20 percent is extracted from silver’s own ores. The lower limit of Ag content in deposits deemed economically profitable to extract varies from 45-50 to 350 grams per ton.
Either silver or gold carrier minerals mineral, has good floatability, so pulse silver Shi Chang by flotation method for sorting. Common collector is xanthenes and black powder, lime, sodium sulfide are potent inhibitors of gold. For containing coarse silver vein of silver ore, flotation separation method commonly used in prior to recovery of coarse grained gold.
In this case, gravity separation set mainly in grinding classification circuit; common separation equipment with jig, shaker, chute, spiral separator and silver plate. When the silver minerals in fine-grained disseminated and other metal sulfide minerals (mainly iron sulfide minerals ) symbiosis, the most commonly used scheme is first a gold-bearing sulfide minerals flotation, won the silver, and then to the silver concentrate cyaniding leaching recovery of silver or other metal in steelmaking process for recovery of gold.
Silver processing equipment
Silver processing equipment includes many machines such as underground mining equipments, silver surface mining equipments, crushing mining equipments, grinding equipments or grinding mill , and other optional equipments such as feeders, screen , washing equipments for silver ore etc. Silver ore crusher is usually used as primary crushing equipment in silver ore processing plants in world silver ore mining industry.
