Umthengisi weMethyl Isobutyl Carbinol (MIBC) eMzantsi Afrika

Yintoni iMethyl Isobutyl Carbinol?

I-Methyl isobutyl carbinol (MIBC, 4-methylpentan-2-ol) yi-branched C6 aliphatic alcohol kunye ne-freathing flotation flother edumileyo kwimisebenzi yemigodi yehlabathi. Iveliswa yi-hydrogenation ye-methyl isobutyl ketone (MIBK). I-MIBC isebenza njenge-frother ngokufunxa kwindawo yokudibana kwamanzi omoya kwiiseli ze-flotation, inciphisa uxinzelelo lomphezulu kwaye izinzise amaqamza omoya enziwe yi-impeller. Ukunyibilika kwayo okulinganiselweyo kwamanzi (~1.7%) kuthetha ukuba yahlulahlula kakhulu kwindawo yokudibana kwamanzi omoya apho ifunekayo, ngelixa i-alkyl chain yayo emfutshane (C6) ithintela ukuqina kwe-froth xa kuthelekiswa ne-frothers ye-chain ende.

Iipropati zeFroth kunye nokusebenza kweFlotation

I-MIBC ixatyiswa kakhulu ngokuvelisa amagwebu akhethiweyo kakhulu — amagwebu atyebileyo kwiiminerali ane-gangue entrainment ephantsi xa kuthelekiswa neoyile yephayini kunye namanye amagwebu. Oku kukhetha kubangelwa kukuzinza kwawo okuphakathi kwamagwebu: amagwebu avelisiweyo ahlala ixesha elide ngokwaneleyo ukuthwala amagwebu aneeminerali ukuya kuphuphuma kwempahla yokuhlamba kodwa aqhekeka ngokulula kumphezulu wamagwebu, evumela iifilimu zamanzi ezithwele amagwebu ukuba zikhuphe amanzi ngaphambi kokuba ziphuphume. I-MIBC isebenza kakuhle kwiidosi eziphantsi kakhulu (ngesiqhelo i-20–100 g/t), okwenza ukuba ingabizi kakhulu kwaye inciphise ukuhanjiswa kwe-reagent phakathi kwezigaba zesekethe.

Iinkcukacha zoNikezelo

I-Terracore Chemicals inikezela nge-MIBC ngeedrama ezingama-200 L kunye nee-IBC kwimisebenzi yokwemba kulo lonke elaseMzantsi nelaseMzantsi Sahara e-Afrika. Njengolwelo oluvuthayo (indawo yokukhanya ~41°C), kufuneka iinkqubo ezifanelekileyo zokugcina nokuphatha. Amaphepha edatha yobuchwephesha kunye nesikhokelo somthamo kwiindidi ezithile zeesekethe ziyafumaneka xa ziceliwe.
