Daim Ntawv Thov: Siv rau flotation ntawm tooj liab ore, txhuas ore thiab zinc ore. Cov ntaub ntawv: hauv kev tooj liab ote flotation, kev pom zoo ntawm ethyl xanthate siv yog 30-100 g / t, thiab rov ua dua tus nqi tuaj yeem ncav cuag ntau dua 90%.

2.dithiophosphates
Tshuaj lom neeg cov khoom: Cov tshuaj dub yog ntsev ntawm dithiophosphate, qhov ib txwm yog sodium dithiophphate (nao2ps2 (C2h5) 2). Cov tsis muaj: Kev sau tau zoo thiab kev xaiv tau zoo thiab tsim nyog rau cov flotation ntawm sulfide cov txiv ntseej xws li tooj liab, txhuas, thiab zinc. Daim Ntawv Thov: Siv rau flotation ntawm kub, nyiaj thiab tooj lossis tooj. Cov ntaub ntawv: Hauv Kub Mine flotation, kev sib haum ntawm cov hmoov dub siv yog 20-80 g / t, thiab rov ua dua tus nqi tuaj yeem ncav cuag ntau dua 85%.

3.Cov xwm yeem
Tshuaj lom neeg cov khoom: Carboxylates muaj cov laj kab muaj carboxylic acid pab pawg, xws li sodium overille (c18H33N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N3N1). Cov tsis muaj: Haum rau cov flotation ntawm oxidized minerals thiab tsis yog xim hlau cov zaub mov. Daim Ntawv Thov: Siv rau cov flotation ntawm cov zaub mov xws li hematite, ilmenite thiab apatite. Cov ntaub ntawv: Hauv apatite flotation, kev sib haum xeeb ntawm sodium ingate siv yog 50-150 g / t, thiab rov ua dua tus nqi tuaj yeem ncav cuag ntau dua 75%.

ob. Tus kuj
Lub ntsej muag muag muag yog siv los ua npuas ncauj ruaj khov thiab ua npuas ncauj tsis sib haum thaum lub cev ua kom cov txheej txheem flotation los pab txhawb qhov txuas thiab sib cais ntawm cov ntxhia cov ntxhia.

1. Tshuaj lom neeg ntawm cov roj ntoo ntoo thuv: lub ntsiab tivthaiv yog terpene sib txuas, uas muaj cov khoom ua npuas zoo. Cov tsis muaj zog: muaj peev xwm ua npuas ncauj muaj peev xwm thiab ua npuas dej ruaj khov. Daim Ntawv Thov: Siv dav hauv cov flotation ntawm ntau hom sulfide ores thiab tsis yog xim hlau. Cov ntaub ntawv: hauv tooj liab Ore flotation, kev pom ntawm cov roj cawv cawv siv yog 10-50 g / t. 2. Tshuaj lom neeg ntawm Butanol: Butanol yog cawv txiv hmab sib txuas nrog cov khoom siv hluav taws xob nruab nrab. Cov tsis muaj zog: Kev ua npuas ncauj kom muaj peev xwm thiab ua npuas zoo. Daim ntawv thov: Haum rau kev flotation ntawm tooj liab, txhuas, zinc thiab lwm yam zaub mov. Cov ntaub ntawv: hauv Lele Ore flotation, butanol yog siv ntawm kev xav ntawm 5-20 g / t.

peb. Cov tswj hwm tau siv los kho tus nqi pH ntawm cov slurry, inhibit lossis qhib cov pob zeb hauv av pob zeb hauv av, yog li kev txhim kho cov pob zeb xaiv.

1. Cov kua qaub zog tshuaj: Lub ntsiab tivthaiv yog calcium hydroxide (ca (Oh) 2), uas yog siv los kho tus nqi ntawm cov slurry. Cov tsis muaj nuj nqis: Tus nqi PHF ntawm cov slurry tuaj yeem hloov kho ntawm 10-12. Daim ntawv thov: dav siv nyob rau hauv flotation ntawm tooj liab, txhuas thiab zinc ores. Cov Ntaub Ntawv: Hauv kev tooj liab Ore flotation, confentration ntawm cov kua qaub siv yog 500-2000 g / t.

2. Tshuaj lom neeg ntawm tooj liab sulfate: tooj sulfate (cuso4) yog feem ntau siv los ua kom cov txiv ntoo ua kom zoo nkauj. Cov tsis muaj zog: Cov nyhuv ua kom zoo tshaj plaws thiab nws yog qhov tsim nyog rau kev flotation ntawm cov zaub mov xws li pyrite. Daim Ntawv Thov: Rau kev ua haujlwm tooj liab, txhuas, thiab zinc cov zaub mov. Cov ntaub ntawv: hauv Lele flotation, lub concentration tooj liab sulfate siv yog 50-200 g / t.
