Mushure mekushandiswa kwemaminerari ekugadzirisa activator: Mukuita kweflotation, mhedzisiro yekuwedzera kutenderera kwemaminerari inonzi activation.Mumiririri anoshandiswa kushandura kuumbwa kweiyo mineral surface uye kukurudzira kuwirirana pakati pemuunganidzi uye mineral surface inonzi activator.
Activation inogona kukamurwa kuita: 1. Spontaneous activation;2. Preactivation;3. Kumuka;4. Vulcanization.
1. Kuzviitira zvinongoerekana zvaitika
Paunenge uchigadzira asiri-ferrous polymetallic ores, iyo mineral surface inongoerekana yaita nemamwe maion anonyungudika emunyu panguva yekukuya.Semuenzaniso, kana sphalerite nemhangura sulfide zvicherwa zvinogara pamwe chete, shoma shoma yemhangura sulfide minerals inogara ichiiswa oxidized mumhangura sulfate mushure mekunge ore yacherwa.Iyo Cu2+ ions mu slurry inobata ne sphalerite pamusoro kuti iite kuti iite, zvichiita kuti zviome kuparadzanisa mhangura uye zinc.Izvo zvinodikanwa kuti uwedzere mamwe maejenti ekugadzirisa akadai se lime kana sodium carbonate kuti awedzere, pamwe nemamwe "asingadzivisike ions" anogona kukonzera activation.
Chechipiri, preactivation
Kuti usarudze chicherwa, wedzera activator kuti uiite.Kana pyrite yakanyanyisa oxidized, sulfuric acid inowedzerwa kuti iparadze iyo oxide firimu pamusoro peiyo pyrite isati yayangarara, ichifumura iyo nyowani, iyo inobatsira kutenderera.
vatatu.pora
Inoreva zvicherwa zvakadziviswa kare, zvakadai se sphalerite iyo yakavharwa ne cyanide, uye inogona kumutswa nekuwedzera mhangura sulfate.
Four.vulcanization
Zvinoreva kutanga kurapa simbi oxide ore ne sodium sulfide kuumba danda resimbi sarufa mineral film pamusoro peiyo oxide ore, uyezve flotation ne xanthate.
Mineral processing reagents anoshandiswa se activator ndeaya:
Sulfuric acid, sulfurous acid, sodium sulfide, copper sulfate, oxalic acid, lime, sulfur dioxide, lead nitrate, sodium carbonate, sodium hydroxide, lead munyu, barium munyu, nezvimwe.
