: [[Smelting]] requires very high [[temperature]]s to [[melt]] the [[mineral]]s from the [[ore]]which is expensive.: [[Extracting Metals by Electrolysis|Electrolysis]] can be done in [[solution]] with water at low [[temperature]]s if the [[mineral]] is [[soluble]] and the [[metal]] does not [[Chemical Reaction|react]] strongly with [[water]]. However This is relatively cheap as only the [[energy]] needed for the [[electrolysis]] is needed.: [[Extracting Metals by Electrolysis|Electrolysis]] must sometimes be done at high [[insolubletemperature]]s to [[melt]] the [[mineral]]s and if it is [[insoluble]] or the [[metal]]s which do [[Chemical Reaction|reactreacts]] with [[water]] then high . This is expensive because it needs [[temperatureenergy]]s are needed to [[meltheat]] the [[mineral]] and then more [[energy]] for [[electrolysis]].: [[Bioleaching]] uses [[bacteria]] to '''extract''' [[mineral]]s from [[ore]] which happens at room [[temperature]] and is then followed by [[Extracting Metals by Electrolysis|Electrolysis]] of [[mineral]]s in [[solution]]. This is relatively cheap but it takes the [[bacteria]] a long time to remove the [[mineral]]s which means it is often not worth the time it takes.: [[Phytomining]] uses [[plant]]s to '''extract''' [[mineral]]s from [[ore]] which happens at room [[temperature]] and is then followed by [[Extracting Metals by Electrolysis|Electrolysis]] of [[mineral]]s in [[solution]]. This is relatively cheap but it takes the [[plant]]s a long time to remove the [[mineral]]s which means it is often not worth the time it takes.
