Yini amakhemikhali asetshenziswa amaminerali asetshenziswayo?

Ama-ejenti asetshenziswayo asetshenziswa ngokujwayelekile adlala indima ebalulekile ekusebenzeni kwamaminerali futhi asetshenziselwa ukulawula nokulawula ukusebenza kwamaminerali. Ama-ejenti asetshenziswayo asetshenziswa ngamaminerali afaka abaqoqi, ama-foaming agents, abalawuli kanye nama-inhibitors.

munye. Abaqoqi
Umqoqi uthuthukisa ukunamathela phakathi kwezinhlayiya zamaminerali nama-bubble ngokushintsha i-hydrophobicity yendawo yamaminerali, ngaleyo ndlela uzuze flotation amaminerali.
1 Okuvamile kufaka phakathi i-ETYL XANTHATE (C2H5OCS2NA) ne-ISOPPROPYL XANTHATE (C3H7OCS2NA). Amapharamitha: umthamo wokuqoqa oqinile, kepha ukhethe kabi, ulungele ukugcwaliswa kwamaminerali we-sulfide. Isicelo: Kusetshenziselwa ukugcwala kwe-Copper Ore, ukuhola ore no-zinc ore. Idatha: Ku-TRPER ORE Flotation, ukugcwaliseka kwe-ETHYL xanthate esetshenzisiwe kungu-30-100 G / T, izinga lokutakula lingafinyelela ngaphezu kwama-90%.

2.Dithiophosphates
Izakhiwo zamakhemikhali: umuthi omnyama ungosawoti we-dithiophosphate, okujwayelekile yi-sodium diethyl dithiophosphate (NAO2PS2 (C2HH5) 2). Amapharamitha: Amandla weqoqo elihle nokukhetha, kufanelekile ukugcwaliswa kwamaminerali we-sulfide anjengethusi, ukuhola, kanye ne-zinc. Isicelo: Kusetshenziselwa ukugcwaliswa kwegolide, isiliva ne-ores yethusi. Idatha: Ku-Gold Minine Flotation, okuhlushwa kwe-powder emnyama esetshenzisiwe yi-20-80 g / t, futhi izinga lokutakula lingafinyelela ngaphezu kwama-85%.

3.CarCowexylates
Izakhiwo zamakhemikhali: ama-carboxylates amakhompiyutha aqukethe amaqembu e-carboxylic acid, njenge-sodium oleate (C18h333nao2). Amapharamitha: alungele ukugcwala kwamaminerali ahlanganisiwe namaminerali angewona ama-metallic. Isicelo: Kusetshenziselwa ukugcwaliswa kwamaminerali anjenge-hematite, ilmenite kanye ne-apatite. Idatha: Ekuthambekeni kwe-Apatite, ukugcwaliseka kwe-sodium oleate okusetshenzisiwe kuyinto engu-50-150 g / t, izinga lokutakula lingafinyelela ngaphezu kwama-75%.

ezimbili. Onyoko
I-Frother isetshenziselwa ukukhiqiza igwebu elizinzile futhi elifanayo ngesikhathi senqubo ye-flotation ukwenza lula ukunamathiselwa kanye nokuhlukaniswa kwezinhlayiya zamaminerali.

1 Amapharamitha: Ikhono elinamandla lamagwebu kanye nokuqina kwegwebu okuhle. Isicelo: Kusetshenziswa kabanzi ekuhambeni kwama-aulfide asheli ahlukahlukene namaminerali angewona amansimbi. Idatha: E-Copper Ore Flotation, ukugxila kowoyela we-Pine Alcohol Olid ngu-10-50 g / t. 2 Amapharamitha: Ikhono elilinganiselayo le-Foaming kanye nokuqina kwegwebu okuhle. Isicelo: Kufanelekile ukugcwaliswa kwethusi, ukuhola, i-zinc nakwezinye izimbiwana. Idatha: Ku-Lead Ore Flotation, i-Butanol isetshenziswa ekuhlolweni kwe-5-20 g / t.

ezintathu. Abalawuli basetshenziselwa ukulungisa inani le-PH le-Slurry, Vimbela noma basebenzise izakhiwo ezingaphezulu kwamaminerali, ngaleyo ndlela kuthuthukise ukukhetha kwe-flotation.

1. I-Lime Chemical Properties: Ingxenye eyinhloko yi-calcium hydroxide (CA (OH) 2), esetshenziselwa ukulungisa inani le-PH yenani le-slurry. Amapharamitha: Inani le-PH le-Slurry lingashintshwa phakathi kuka-10-12. Isicelo: Kusetshenziswe kabanzi ekutholeni ithusi, ukuhola kanye ne-zinc ores. Idatha: E-Copper Ore Flotation, ukugcwala kwe-lime okusetshenzisiwe kungu-500-2000 g / t.

2 Amapharamitha: Umphumela we-activation umangalisa futhi kufanelekile ukugcwaliswa kwamaminerali anjenge-pyrite. Isicelo: Ukuqalisa kwethusi, ukuhola, kanye namaminerali eZinc. Idatha: Ku-Lead Ore Flotation, ukugcwaliseka kwe-sulfate yethusi esetshenzisiwe kungu-50-200 g / t.
