Txhawm rau txhim kho kev xaiv cov txheej txheem (txhim kho cov txiaj ntsig thiab cov neeg sawv cev ua npuas dej uas muaj txiaj ntsig zoo ntawm cov roj hmab, cov tswj hwm feem ntau siv hauv cov txheej txheem frotation. Cov kev kho hauv cov txheej txheem frotation suav nrog ntau cov tshuaj lom neeg. Raws li lawv lub luag haujlwm hauv cov txheej txheem frolotation, lawv tuaj yeem faib ua cov txheej txheem, cov neeg sawv cev, cov neeg sawv cev hauv nruab nrab, cov neeg sawv cev hauv nruab nrab uas tuaj yeem tiv thaiv lossis txo cov adsorption lossis kev ua tiav ntawm cov Tus sau rau saum npoo ntawm tsis-flotation minerals, thiab tsim hydrophilic zaj duab xis nyob rau saum npoo ntawm cov merals. Raws li lawv cov tshuaj lom neeg muaj pes tsawg leeg, lawv tuaj yeem faib ua ob pawg: inorganic sib xyaw thiab cov organic polymer sib txuas.
Lub luag haujlwm ntawm Inhibitors
Thaum lub sijhawm flotation flotation, inhibitors yog cov neeg sawv cev uas tuaj yeem tiv thaiv lossis txo cov zaub mov tsis yog-fydrophilic zaj duab xis nyob rau saum npoo ntawm cov merals. Raws li lawv cov tshuaj lom neeg muaj pes tsawg leeg, lawv tuaj yeem faib ua ob pawg: inorganic sib xyaw thiab cov organic polymer sib txuas.
Mechanism ntawm inhibitics ua ntawm inhibitors
Inhibitics mechanism ntawm inhibitors yog: (1) Tsim cov yeeb yaj kiab hydroughilic nyob rau saum npoo ntawm cov hom phiaj uas tsis yog-fihromate inhibiting malena; (2) Tsim los ntawm Hydroid Adsorption ntawm qhov chaw tsis-flocation mineral thiab adsorine slurry thiab adsorbed nyob rau saum npoo ntawm sphalerite (iron sib xyaw) kom inhibit nws. Silic hmoov txhuv nplej siab thiab lwm cov minerals uas tsis tau npaj rau cov flotation kuj yooj yim hydrophilic coloid adsorption zaj duab xis yog tsim rau saum npoo; (3) Ib zaj yeeb yaj kiab hydrough adstorption zaj duab xis yog tsim nyob rau saum npoo ntawm cov me nyuam yaus ntawm sulium sulfide, uas tuaj yeem adsorbed ib tug hydroughilic ion Adsorption zaj duab xis yog tsim nyob rau saum npoo ntawm tsis-flotation sulfide cov zaub mov; (4) Qee tus muaj zog oxidants decompose cov sau zaj duab xis adsorbed nyob rau saum npoo ntawm tsis-flotation sulfide cov zaub mov kom ua rau nws hydrophilic nto.
