Inhloso yokungezwa kwamakhemikhali okunengqondo ukuqinisekisa ukusebenza okuphezulu kwamakhemikhali ku-slurry nokugcina ukugxila okulungile. Ngakho-ke, indawo ye-dosing nendlela ye-dosing ingakhethwa ngokunengqondo ngokususelwa ezimfanelweni ze-ore, uhlobo lomenzeli kanye nezidingo zenqubo.
1. I-Dosing Indawo
Ukukhethwa kwendawo ye-dosing kuhlobene nokusetshenziswa kanye ne-solubility ye-ejenti. Imvamisa, i-adjumper ephakathi ingezwe emshinini wokugaya, ukuze ususe imiphumela elimazayo ye-ion "engenakugwenywa" eyenza njengokusebenza noma ku-inhibitors ku-flotation. I-inhibitors kufanele ingezwe ngaphambi komqoqi futhi imvamisa ingezwe emshinini wokugaya. Isishoshovu kwesinye isikhathi singezwa ethangini lokuxuba futhi lixubene ne-slurry ethangini lesikhathi esithile. I-ejenti yomqoqi kanye ne-Foaming ingezwa ethangini lokuxuba kanye nethangi noma umshini we-flotation. Ukuze ukhuthaze ukuqedwa kanye nokuhlakazwa kwabaqoqi be-insoluble (njenge-cresol black powder, i-powder emhlophe, amalahle, uwoyela, njll. Isikhathi sesenzo samaminerali sivame ukungezwa emshinini wokugaya.
Ukulandelana okujwayelekile kwe-dosing yile:
.
.
Ngaphezu kwalokho, ukukhetha kwendawo ye-dosing kufanele futhi kubheke uhlobo lwe-ore nezinye izimo ezithile. Isibonelo, kwezinye izitshalo ze-sulfide-iron ore flotation-iron ore flotation, i-xanthate ingezwe emshinini wokugaya, okuthuthukisa inkomba yokuhlukanisa yethusi. Ngaphezu kwalokho, umshini we-flotation we-perlel Ukuze wandise isikhathi sesenzo somqoqi, kuyadingeka futhi ukwengeza umenzeli emshinini wokugaya.
2. Indlela ye-Dosing
Ama-reagents we-flotation angangezwa ngesikhathi esisodwa noma kuma-batches.
Ukungezwa kwesikhathi okukodwa kubhekisa ukufaka i-ejenti ethile ku-slurry ngasikhathi sinye ngaphambi kokufakelwa. Ngale ndlela, ukugcwala kwe-ejenti endaweni ethile yokusebenza kuphezulu, isici sokuqina sikhulu, futhi okungeziwe kulula. Ngokuvamile, kulabo abancibilikisa kalula emanzini, ngeke bashaye ngomshini we-foam. Kuma-ejenti (njenge-soda, i-lime, njll.) Engakwazi ukusabela kalula futhi ungaphumeleli ku-slurry, i-dosing yesikhathi esisodwa ivame ukusetshenziswa.
I-Batch dosing isho ukufaka amakhemikhali athile kumabhethri amaningana ngesikhathi senqubo ye-flotation. Ngokuvamile, ama-60% kuye kwangama-70% wenani eliphelele angezwa ngaphambi kokufakelwa, kanti ama-30% asele kuye kwangama-40% angezwa ezindaweni ezifanele ngamabhathi ambalwa. Ngale ndlela amakhemikhali e-DOSIng kuma-batches angagcina ukugxila kwamakhemikhali kanye nomugqa wokusebenza kwe-flotation futhi asize ukuthuthukisa ikhwalithi yokugxila.
Kulezi zimo ezilandelayo, okungeziwe kwe-batch kufanele kusetshenziswe:
(1) Ama-ejenti okunzima ukuncibilikisa emanzini futhi asuswe kalula yi-foam (njenge-oleic acid, abaqoqi be-anic omine).
(2) Ama-ejenti okulula ukusabela noma ukubola ku-slurry. Njenge-carbon dioxide, i-sulphur dioxide, njll., Uma zingezwa kuphela endaweni eyodwa, ukusabela kuzohluleka ngokushesha.
(3) Imithi imithamo yakhe idinga ukulawulwa okuqinile. Isibonelo, uma ukugcwala kwendawo i-sodium sulfide kuphezulu kakhulu, umphumela okhethiwe uzolahleka.
