Ag is recovered for a profit mostly from galena-bearing deposits therefore have a look at Pb-Zn deposits where high-T deposits have the highest grade:

(1)Magmatic lead-zinc deposits

(1)Polymetallic Sn-(Ag-Pb-Zn-Cu) vein-type deposits in intermediate subvolcanics (

(2)In-bearing Zn–Sn–Cu veins and replacement deposits in granites D)

(3)Polymetallic Ag-Zn-Pb skarn deposits

(1)Skarn deposits s.s.

(2)Skarn-vein-type deposits (mixed-type)

(4)Volcanic massive sulfide Pb-Zn-Cu-In deposits (VMS)

(1)Kuroko-type

(2)Besshi-type and Abitibi/ Ural-type (

(3)Cyprus-type and Atlantic-type

(4)Iberian-type/ Greenstone-belt-type

(5)VMS deposits in medium tohigh grade metamorphic terrains of unknown type

(2)Structure-relatedlead-zinc deposits

(1)Unconformity-related Pb-Zn-F-Ba deposits

(2)Thrustbound and fold-related Pb-Zn deposits

(3)Replacement deposits (sulfidic and non-sulfidic)

(3)Sedimentary lead-zinc deposits

(1)SEDEX/SMS Pb-Zn-Ag-(Ba)-FeS-(Sn) deposits

(2)Sandstone-hosted Pb-(Zn) deposits

(1)Sulfidic subtype

(2)Non-sulfidic subtype

(3)Carbonate-hosted Pb-Zn-(Ag) deposits (sulfidic and non-sulfidic)

(1)Pb-Zn-Ba-F-(Ag) flexure- to horstbound sulfidic deposits (plus gem-quality sphalerite)

(2)Pb-Zn-(As-Ba) flexure- to horstbound sulfidic-non-sulfidic

(3)Pb-Zn-Ba-Ag-(Ni-Co) horstbound sulfidic-(non-sulfidic)

(4)Pb-Zn-Ge-Mo faciesbound sulfidic

(5)Carbonate- evaporite-associated Pb-Zn deposits

(6)Karst-related non-sulfidic Ba-Zn-(Pb) deposits

(7)Non- sulfidic Zn hypogene-(supergene) replacement deposits

(4)Ge-enriched coal seams

(4)Metamorphiclead-zinc deposits
