Codsiga Dhammaan-Slime Cyanidation Kaarboon-in-Pulp Habka Soosaarida Dahabka ee Shiinaha

Hordhac

Dhinaca macdanta iyo soo saarista dahabka, habka loo yaqaan ' caro -in-pulp (CIP)' ee loo yaqaan 'slime cyanidation' ayaa soo ifbaxay isagoo ah farsamo muhiim ah. Habkani wuxuu si gaar ah waxtar ugu leeyahay daawaynta macdanta dahabka ee leh dhoobo sare iyo cabbirka walxaha khafiifka ah. Shiinaha, iyadoo ay jiraan kheyraadkiisa dahabka ee hodanka ah iyo baahida sii kordheysa ee dahabka, habka CIP ee loo yaqaan 'slime cyanidation' wuxuu helay codsi ballaaran, isagoo door muhiim ah ka ciyaaraya warshadaha macdanta dahabka ee gudaha.

Mabaadi'da All-Slime Cyanidation Kaarboon-in-Pulp Geedi socodka

Habka CIP-ka ee cyanidation-ka oo dhan waa isku-darka laba tallaabo oo muhiim ah: Cyanidation leaching iyo nuugista kaarboon-ku-jirta saxarka.

Leaching Cyanidation

Daadinta Cyanidation waa udub-dhexaadka habka. Macdanta dahabka ah, ka dib marka la burburiyo, la shiido, oo la miiro, waxaa lagu qasaa xal cyanide ah . Marka ay jiraan xaalado ku habboon pH, heerkulka, iyo oksijiinta, dahabka ku jira macdantu wuxuu la falgalaa ayoonnada cyanide si uu u sameeyo isku-dhafan cyanide dahab ah oo milmi kara. Falgalka kiimikada waxaa si fudud loogu qeexi karaa sidan:

Dareen-celintani waxay u oggolaanaysaa dahabka in laga milo matrix-ka macdanta ee xalka, oo laga sooco macdanta gangue.

Adsorption Kaarboon-in-Pulp

Marka dahabka lagu milmo xalka cyanide, Kaarboon firfircoon oo granular ah ayaa si toos ah loogu daraa saxarka wasakhaysan. Kaarboon firfircoon wuxuu leeyahay awood nuugid oo xooggan oo loogu talagalay isku-dhafka cyanide-ka dahabka ah. Iyada oo loo marayo hababka nuugista jirka iyo kiimikada, dahabka waxaa lagu nuugaa dusha sare ee kaarboon firfircoon, taasoo si wax ku ool ah uga soocda dahabka iyo xalka cyanide-ka. Tallaabadani waxay meesha ka saaraysaa baahida loo qabo hababka kala-soocidda adag-dareere ee isku-dhafan ee hababka cyanide-ka dhaqameed, iyadoo fududaynaysa habka guud ee soo saarista.
