Modern Silver Mining. Even these ores are found in small quantities, and many tons of material must be mined to produce just a few ounces of silver. At least 80 percent of the world's silver is produced instead as a byproduct of mining for other metals such as gold, copper, lead, zinc, and uranium. Primary and secondary sources of silver ore.
Gold Refining. Gold mines process ore using various techniques to produce an alloy composed primarily of gold and silver, which is called a dore bar. The composition of dore can vary significantly between mines, but generally the gold dore bars the Perth Mint processes are composed of between 7080% gold and 1015% silver.

Gold ores are classified "freemilling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory goldbearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of goldentrapment in different associated mineral phases before an appropriate ...

Platinum Processes Uses. A solid platinum nugget. Image from 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 size of platinum grains or nuggets varies from small granules to pebbles weighing up to 20 pounds (9 kg) or more.
The term "precious metal" refers to the metals gold, silver, platinum and the other platinumgroup metals (PGMs), namely: palladium, rhodium, iridium, ruthenium and osmium. They are noble metals, in that they resist attack by acids and other reagents and do not corrode easily (although silver .
· Precious Metal Refining: Dore is a mixture of gold and silver typically containing less than 5% base metal exact composition varies widely depending on its source and processing history. Dore producers, in deciding whether or not to refine their dore, can custom design a facility around a single feedstock.
· Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 6070% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.
milling platinum metals gold and silver ore. Gold extraction. Gold occurs principally as a native metal usually alloyed to a greater or lesser extent with silver as electrum or sometimes with mercury as an amalgam Native gold can occur as sizeable nuggets as fine grains or flakes in alluvial deposits or as grains or microscopic particles known ...

First, platinum and silver are innately different: this goes beyond appearances and into the properties of the metals themselves. Gold is rarer than silver, and platinum is rarer than gold, meaning platinum is much, much more rare than silver. And if you're paying attention, that means that platinum will be more valuable than silver to see ...

· Those powdery materials might contain small flecks of gold, silver, and platinum scrap. The appliion of high heat causes those precious metals to separate and be left behind after dust, sawdust and other undesirable contents are reduced to ash. Give us a call at and we can explain how this works.
sulphur. The platinum group metals, together with some gold, total about fifty ounces to the ton. The complete process of extraction consists essentially of enriching this matte to approximately 65 per cent content of platinum metals and then treating this concentrate with acids to separate the individual platinum group metals from each
