- Kusagadzikana kwefuro:Kuwedzera kwesimba reionic kunogona kukanganisa froth yekuyangarara, zvichideredza kusarudzwa kwekuyangarara uye kupora kwe concentrate.
- Kushandiswa kwe reagent kwakawedzerwa:Zvinodiwa kuti pave nezvinhu zvakawanda zvinogadzirisa dambudziko rekugadzirisa zvinhu, zvichiwedzera mari yekushandisa uye njodzi yemakemikari asingadiwe.
- Kuoma kwekuparadzanisa:Kusarudza kunoderera sezvo maion emhangura, calcium, kana sulfate akanyungudutswa achikanganisa molybdenite uye scheelite flotation. Izvi zvinoita kuti kupatsanurwa kuve kwakaoma, zvichida kugadziriswa nguva dzose kwemuyero we reagent inogadziriswa.
- Kutarisa maitiro:Kuwanda kwezvicherwa kunoda kudzorwa kwakasimba uye kutariswa—sekuongororwa kwepH nguva dzose kana kufambiswa kwemhepo—kuchengetedza kushanda zvakanaka kweflotation uye kutarisira reagent dosing zvinobudirira.
Muenzaniso: Miti inogadzira slurry ine mineralization yakawanda inowanzoshandisa Lonnmeter inline analyzers kugadzirisa otomatiki collector uye depressant feed rates, kuderedza kusagadzikana kwefuro uye kutsigira nzira dzekugadzirisa flotation process.
