Galena is the principal mineral found in lead and contains roughly 87% of leadâ??s weight. In addition, lead is also found in ore that contains either silver or copper zinc. It is commonly known to be extracted from these minerals.

∙ 12y agoTin is extracted from its ore by heating it with carbon. The only commercially recovered ore of tin is casserite, with contains an oxide of tin (SnO2). Use the link below to check facts and learn more. A process for the direct recovery of tin, as an organo hydrocarbyl tin compound, from reduced but unrefined tin ores and ore slags is described, wherein the ore is reacted directly with a hydrocarbyl halide to form an organo hydrocarbyl tin compound which can then easily be removed and separated from the tin-depleted ore residue.

∙ 15y agohe electrolyte for this process is a mixture of lead fluorosilicate (PbSiF6) and hexafluorosilicic acid (H2SiF6) heated to 45°C. Cathodes are thin sheets of pure lead and anodes are cast from the impure lead to be purified. A potential of 0.5 volts is applied. At the anode, lead goes into solution, as do metal impurities that are less noble than lead. Impurities that are more noble than lead, such as silver, gold, and bismuth, flake from the anode as it dissolves and settle to the bottom of the vessel as "anode mud." Pure metallic lead plates onto the cathode, with the less noble metals remaining in solution. Because of the high cost of electrolysis, this process is used only when very pure lead is needed. Otherwise the Parkes process followed by the Betterton-Kroll process are used to purify lead.[1]

∙ 6y agoThere are many ores of lead and the details depend on the compounds present. Galena ( one of the main lead bearing ores) has to be crushed into small pieces, then heated until the lead sulfide present is converted to lead oxide. This is called roasting . The lead oxide which results is heated with carbon in a blast furnace which produces lead.
Lead poisoning is a possibility if you are exposed to lead (the metal, fumes, etc) for too long. This should be taken into account, even if the extracting of lead is an experiment on a small scale. The gases produced in the roasting of ores are also rather nasty so any experiments, even on the smallest of scales, should be done in a fume cupboard.

What factors determines the method used to extract a metal?
Its position on the reactivity series. The more reactive the metal, the harder it is to extract from its ore.
What method is used to extract metals that are above carbon in the reactivity series?
Usually they put electricity into the metal ion solution to reverse the ionization
Why is electrolysis used to extract certain metals?
Electrolysis can be used for the following purposes:Electroplating a baser metal with a more attractive metal. e.g. electroplating brass with goldRefining of impure metals. e.g. to remove impurities from copperElectrometallurgy - to extract metals from their compounds
Why is it sometimes not economically viable to extract a metal?
Sometimes extracting the metal would cost more than would be economically beneficial, either because of where it is located, the process that would need to be used to extract it, or other reasons.
Does lead have acid and can it melt metal?
Lead is a metal. Metals react with acids to form salts. Metals can be used to make alkalies, but not acids.

How can carbon be used to extract a metal from its ore?
Metals are extracted from ores. An ore is a rock that contains enough of a mineral (metal compound) for the metal to be extracted from it. Most metals are extracted from an ore by reduction with carbon or by electrolysis.
What method to be use to separate powdered iron and powdered aluminum?
Iron is a magnetic metal, aluminium is not.So, a simple method is to use a magnet for this separation.Magnetic separation is frequently used to extract iron from wastes.
Describe the method of purification of copper?
The method used to extract Cu from its ore depends on the nature of the ore.

Name three general methods for extracting a metal from its ore?
The three method generally used to extract metals from ores are dependent on their reactivity. The first method is electrolysis, which is used for metals like aluminum and magnesium that have a high reactivity. The second is extraction by reaction with either carbon or carbon monoxide, which is used for less reactive metals like iron, lead and zinc. The third and final method is the use of hydrogen and this method is used for unreactive metals like gold, silver and copper. The third method is used in a variety of ways as many of these metals don't need to be separated from their ores but chemical reactions may be required to remove other contaminant materials.

What metal is used for xray protection?
lead
Why is carbon used to extract metal from ores?
It's used as a reducing agent. The carbon (or specifically the Carbon Monoxide produced by the heat of the furnace) "grabs" the oxygen from the ore (an oxide) producing Carbon Dioxide and the metal. The combustion of the carbon also provides the heat required for the extraction. If the ore is not an oxide, another method of extraction needs to be used.
What is the metal used in ancient roman waterworks?
Most of the metal used in ancient Roman piping was lead.
