Silver
Silver is malleable which means it can be hammered into thin sheets. It is also ductile, meaning it can be drawn into wire. Relation to Mining. 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

Ore Minerals : What are Ore Minerals?
Ore Minerals. An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable

Extracting a metal from its ore
Metals with low chemical activity, such a gold and silver are normally found in their pure state. Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals. Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction.

Copper Concentrates
Copper concentrate is smelted and converted to metallic copper, which allows it to attain forms that can be submitted to further refining, more than 99% pure, as in copper anode and copper blister. The main application of copper anode is to use it as raw material in the process of electrolytic refining, to produce the electrolytic refined cathode, purity 99.99%.

How do you separate gold silver and copper?
To separate silver from an ore containing a quantity of copper, you need to heat the ore sample to a level sufficient to melt the silver but leave the copper in a still-solid state. Furthermore, how do you separate gold at home? Separate the gold from unwanted rocks and minerals using one of several methods. You can mix the gold ore with sodium

Silver''s attractiveness and the ease with which it can be worked make it a popular material for use in jewellery. Sterling silver is an alloy of 92.5% silver and 7.5% copper. Sterling silver is tougher than pure silver, so it can be used to make cutlery, serving trays and other ornaments and decorative tableware.

copper extraction and purification
Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.

Occurrence of Metals: Metal Ores, Methods of Extraction
Metals that aren''t extremely reactive are grouped together at the bottom of the reactivity scale. By heating them alone, these metals can be converted to metals. Mercury, for example, is extracted from its ore, cinnabar (HgS), using a heating process. Heating can also be used to extract copper from its sulphide ore (Cu2S).

Carbon Reduction Method Chemistry Tutorial
The more active (or reactive) a metal is, the more stable the compound it forms and the greater the energy required to produce the metal from its ore. Very active metals ( Group 1 , Group 2 and aluminium) require electrolysis to extract the metal while very inactive metals like gold and silver can occur in nature as the element so require no energy to extract the metal.

Copper Mining and Extraction Sulfide Ores
Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid.

Silver mining
Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. As such, most silver produced is refined from sulfide ores such as galena (lead) or chalcopyrite (copper) which contain small amounts of silver. Many of these ores are mined for their value as sulfide ores, and silver is extracted as a

Which metals can be extracted through electrolysis?
Answer (1 of 4): All metals can be extracted through electrolysis. The question of economics does play a role in what you want to extract, however. For example, it is often easier to obtain Zn from roasting despite the fact that we can extract it from electrolysis: Roasting: 2ZnO(s) + C(s) \xrig...

Extraction of Metals- A metal is a material that is extracted from the ore. When it’s been freshly prepared, polished, it shows a lustrous appearance and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires).

Quality of Ores fit for the Solving Process. There is no process so suitable for all kinds of ores as the solving process. Generally considered, all silver ores can be treated by the solving process which are subjected to the pan amalgamation after roasting ; but in many instances— especially with the rebellious ores— a better result is obtained by this than by working in pans.

Extracting a metal from its ore 2010
Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3 Cu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3 Cu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2

Why do we extract copper from low grade ores?
Bacteria feed on the low grade metal ores and form a solution of copper ions, called a leachate. Slow process
Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena.
