how to processing silver ore
Silver ore can be divided into the following categories:
1. Containing a small amount of silver sulfide ore, silver is the only recycling useful components, sulfide are mainly pyrite, other associated with recovery value less components, usually referred to as a single silver ore.This kind of ore general property silver flotation cyanidation, they are available.
2. The silver lead-zinc ore, silver, lead and zinc has the collection value, is a major mineral raw materials in the production of silver.Current production by flotation method common to enrichment of silver in lead concentrate and zinc concentrate, smelter comprehensive recovery of silver.Silver general loss of pyrite concentrate in pyrites slag.
3. The silver gold ore and gold and silver ore, gold silver and gold symbiosis, composition of alloy often referred to as a silver gold or gold and silver ore, gold when recycled quite amount of silver, such close symbiosis with pyrite ore often.General primary enrichment by flotation method for mineral concentrates, with gold and silver cyanidation on-site output or send smelter comprehensive recovery of gold and silver.
4. Silver copper sulfide ore: most countries copper sulfide ore containing a small amount of silver, silver exists in natural gold and other minerals, can be in enrichment of gold and silver as a by-product from copper sulfide concentrate, comprehensive recovery of gold and silver smelting plant.
5. Silver cobalt ore: some cobalt, silver exists in calcite, and arsenopyrite, rhombic arsenic ore symbiosis.Such deposit less, generally choose don’t process more complicated.
6. Silver antimony: such ore recovery of silver at the same time, antimony, lead, and other useful components.

Silver and gold class ore dressing method
Silver and gold class ore dressing method, the main use or flotation cyanidation.Decided to adopt flotation or cyanide is silver mineral composition of the main factors.When silver minerals mainly argentite and natural silver, flotation and cyanide, are available;But when the ore contains numerous pyrargyrite, reddish silver, selenium the difficult cyanide minerals such as silver, can only use flotation.Flotation with cyanide recovery is distinct, general cyanide recovery rate is higher.Lead and zinc copper associated silver ore due to its mineral composition is more complicated, symbiosis, embedded bout, and each are not identical, such as oxidation effect also have very big difference, but in terms of ore dressing method, flotation is a widely used method.In general, lead and zinc copper associated silver ore dressing recovery better than silver and gold type ore is low, generally between 50-70%.
