Umthengisi we-Isopropyl Ethyl Xanthogen Formate (IPEXF) eMzantsi Afrika

Yintoni i-Isopropyl Ethyl Xanthogen Formate?

I-Isopropyl ethyl xanthogen formate (IPEXF) yi-xanthogen formate ester — uhlobo lomqokeleli olwahlukileyo kwi-xanthates okanye ii-dithiophosphates zesiqhelo, ngokusekelwe kwiqela elisebenzayo le-xanthogen dithioformate. Iifomathi ze-Xanthogen zenziwe ngokukodwa ukuphucula ukukhetha kunye nokungabandakanywa kwamanzi kwi-collector layer eyenziwe kwi-precious metal kunye ne-PGM mineral surfaces xa kuthelekiswa nabaqokeleli be-xanthate abaqhelekileyo. Zifunxa kwi-sulphide kunye ne-native metal surfaces ngokudibanisa iindlela ze-chemical and physical adsorption, kwaye zinokuvelisa ii-hydrophobic collector layers ezinamandla ngakumbi kunezongezo ze-xanthate ezifanayo.

I-PGM kunye ne-Gold Flotation

I-IPEXF isetyenziswa kakhulu kwi-PGM nakwi-gold flotation circuits njenge-specialty co-collector kunye ne-primary xanthate okanye i-DTP collectors. Ukuphuculwa kwayo kwe-hydrophobicity kumphezulu kunokuphucula ukubuyiselwa kwee-particles ze-PGM mineral kunye negolide yendalo engafunyanwanga ngokupheleleyo ngabaqokeleli bemveli. Kwi-PGM circuits, i-IPEXF ngamanye amaxesha isetyenziselwa ukuphucula i-flotation yeeminerali ze-PGM kwiindawo ze-ore ezikufutshane nomphezulu apho ukusebenzisana komphezulu we-collector-mineral kwenze buthathaka khona. I-chemistry yayo eyahlukileyo kancinci yokuqokelela xa ithelekiswa ne-xanthates inokuba luncedo ekubuyiseleni izigaba ezithile ze-PGM mineral.

Iinkcukacha zoNikezelo

I-Terracore Chemicals inikezela nge-IPEXF ngeedrama ezingama-200 L kwimisebenzi yokwemba i-PGM kunye negolide. Idatha yobugcisa kunye neengcebiso zomthamo wokusetyenziswa kunye neenkqubo zokuqokelela ezisisiseko ziyafumaneka xa ziceliwe.
