1. Mmalite ozugbo
Mgbe a na-ahazi ores polymetallic na-abụghị nke ígwè, elu nke ịnweta ahụ ga-eji ion nnu soluble meghachi omume ozugbo n'oge usoro egweri.Dịka ọmụmaatụ, mgbe sphalerite na ọla kọpa sulfide mineral na-ebikọ ọnụ, obere obere ọla kọpa sulfide mineral ga-abụ oxidized n'ime ọla kọpa sulfate mgbe e gwuchara ọla.ions Cu2+ dị na slurry na-emeghachi omume na elu sphalerite iji rụọ ọrụ ya, na-eme ka ọ sie ike ikewapụ ọla kọpa na zinc.Ọ dị mkpa ịgbakwunye ụfọdụ ndị na-edozi ihe dị ka lime ma ọ bụ sodium carbonate iji mee ka ọ daa, yana ụfọdụ "ion na-apụghị izere ezere" nke nwere ike ime ka ọ rụọ ọrụ.

Ka ịhọrọ ịnweta, tinye onye na-arụ ọrụ ka ọ rụọ ọrụ.Mgbe pyrite na-agbaze nke ukwuu, a na-agbakwunye sulfuric acid iji gbazee ihe nkiri oxide n'elu pyrite tupu flotation, na-ekpughe elu elu ọhụrụ, nke bara uru na mmiri mmiri.
atọ.naghachi
Ọ na-ezo aka na mineral ndị e gbochiri na mbụ, dị ka sphalerite nke cyanide na-egbochi ya, a pụkwara ịkpọlite ya site n'ịgbakwunye sulfate ọla kọpa.
Anọ.vulcanization
Ọ na-ezo aka na mbụ ịgwọ ọla oxide ore na sodium sulfide iji mepụta oyi akwa nke ihe nkiri ịnweta sọlfọ metal n'elu oxide ore, wee na-efegharị na xanthate.
Reagents nhazi mineral eji dị ka activators bụ:
Sulfuric acid, sulfurous acid, sodium sulfide, ọla kọpa sulfate, oxalic acid, wayo, sọlfọ dioxide, lead nitrate, sodium carbonate, sodium hydroxide, lead nnu, barium nnu, wdg.
