Other minerals, like sphalerite, pyrrhotite,ite and hematite sometimes carry small amounts of gold as well. Gold also occurs as tellurides such as calaverite. Common gangue minerals in gold ores include quartz, fluorite, calcite and pyrite, but many others can be found in smaller amounts.

Gold occurs in nature mainly as the metal and as various alloys. Itplete series of solid solu tions with silver, copper, nickel, palladium, and platinum. In association with the platinum metals, gold occurs as free gold as well as in solid solution.
The results showed that the acid leaching residue contained Au 68.22 g/t, Ag 92.71 g/t, Fe 0.44 , As 0.10 , and S 0.55 . Gold and silver minerals existed as native gold
Unlike gold, silver rarely appears in nature in the form of nearly pure nuggets. In the raw state, silver ores are almost always foundbination with other minerals. Silver is often a by product in lead, copper and gold mines. You can recognize a potentially silver bearing rock by dark, sooty streaks or dark crystals. Different types of silver ores are found in different parts

Silver as a Native Element Mineral Silver is rarely found as a native element mineral. When found, it is often associated with quartz, gold, copper, sulfides of other metals, arsenides of other metals, and other silver minerals. Unlike gold, it is rarely found in significant amounts in placer deposits.
To know what type of rock is gold associated with you must see that the mineralsmon in placer deposits are platinum, iridosmine,ite, iron pyrites, ilmenite, zircon,s, rutile and barytes wolfram, scheelite, brookite and diamonds aremon. Diamonds are associated with gold in Brazil, and also occasionally in the Urals and in the United States. In
Mining was one of the most prosperous activities in Roman Britain.Britain was rich in resources such as copper, gold, iron, lead, salt, silver, and tin, materials in high demand in the Roman Empire.The Romans started panning and puddling for gold. The abundance of mineral resources in the British Isles was probably one of the reasons for the Roman conquest of Britain.
Silver can bebined with a number of different elements such as sulfur, arsenic, antimony or chlorine to form a variety of minerals and ores, such as argentite, chlorargyrite, and galena. It is also found in very small amounts in gold, lead, zinc and copper ores. Silver is malleable which means it can be hammered into thin sheets.
Other minerals, like sphalerite, pyrrhotite,ite and hematite sometimes carry small amounts of gold as well. Gold also occurs as tellurides such as calaverite. Common gangue minerals in gold ores include quartz, fluorite, calcite and pyrite, but many others can be found in smaller amounts.
Except occurring as silver minerals, silver in gold ores is often present in electrum, and occasionally in kustelite. Silver rich electrum and kustelite tarnish quickly in air, and form a silver sulfide layer of 1 2 µm in thickness in the presence of sulfide ions, which can limit the access of cyanide solution.

In refractory ore the gold is locked in sulphide minerals, so to achieve satisfactory levels of gold recovery additional processing is required before cyanidation. Sulphide minerals in refractory ores are converted to oxides by either roasting or biological leaching to release the gold. In biological leaching the oxidation is caused by the action of specific bacteria on the ore. The

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 as color embedded in rock minerals.
