The present invention relates to a process for dissolving metals in perhalide containing ionic liquids, and to the extraction of metals from mineral ores; the remediation of materials contaminated with heavy, toxic or radioactive metals; and to the removal of heavy and toxic metals from hydrocarbon streams. 125-. (canceled)26. A method of extracting metals and metal compounds from aqueous solutions comprising contacting the aqueous solution with an ionic liquid having the formula:{'br': None, 'sup': +', '−, '[Cat][X]'}{'sup': '+', 'claim-text': {'sup': '−', '[X] represents one or more perhalide anions,'}, 'wherein: [Cat] represents one or more cationic species, and'}wherein the ionic liquid is free of additional solvents and/or oxidants.27. A method according to claim 26 , wherein [X] comprises at least one perhalide anion selected from [I] claim 26 , [BrI] claim 26 , [BrI] claim 26 , [ClI] claim 26 , [Br] claim 26 , [ClBr] claim 26 , [BrCl] claim 26 , [ICl] claim 26 , or [Cl].28. A method according to claim 27 , wherein [X] comprises at least one perhalide anion selected from [BrI] claim 27 , [BrI] claim 27 , [ClI] claim 27 , [ClBr] claim 27 , [BrCl] claim 27 , or [ICl].29. A method according to claim 27 , wherein [X] comprises at least one perhalide anion selected from [I] claim 27 , [Br] claim 27 , or [Cl].30. A method according to claim 26 , wherein [Cat] is a cationic species selected from the group consisting of: ammonium claim 26 , azaannulenium claim 26 , azathiazolium claim 26 , benzimidazolium claim 26 , benzofuranium claim 26 , benzotriazolium claim 26 , borolium claim 26 , cinnolinium claim 26 , diazabicyclodecenium claim 26 , diazabicyclononenium claim 26 , diazabicyclo-undecenium claim 26 , dithiazolium claim 26 , furanium claim 26 , guanidinium claim 26 , imidazolium claim 26 , indazolium claim 26 , indolinium claim 26 , indolium claim 26 , morpholinium claim 26 , oxaborolium claim 26 , oxaphospholium claim 26 , oxazinium claim 26 , oxazolium claim 26 ...
