Indlela Yokwandisa Amanani Okubuyisa Igolide ngo-15% Ezimayini Ezincane

Umbhali : I-SBM Time: 13 Aprili 2026 Abafundi Abaningi:

Summary: Finyelela ukulondolozwa kwegolide okungu-15% okuphezulu ngokusebenzisa izinhlelo zokuhlobisa nokugaywa okuqhutshwa kahle. Umhlahlandlela ochwepheshe wemayini emancane ekukhululweni, ekufundisweni nasekusebenzeni kahle kwe-cyanidation.

For small-scale igolide miners in regions like Ghana’s Ashanti belt or Sudan’s Red Sea Hills, increasing igolide recovery rates is the single most effective way to transform a marginal operation into a highly profitable one.

Kodwa abaningi bamawokhazi balahlekelwa u-15% kuya ku-30% wegolide wabo emashumini, hhayi ngoba igolide labo lihle, kodwa ngoba umjikelezo wokuphonsa nokuwahlukanisa awunakwenzeka kahle ukuze kuzuzwe ukukhululwa okuphezulu. Le nqubo yobunjiniyela ikubonisa ukuthi ungahlela kanjani kabusha isixhumanisi esibalulekile ukuze kukhuliswe amazinga okutholwa kwegolide ngo-15% noma ngaphezulu.

Uhlobo lwe-"Gold Liberation" trap: Kungani Usayizi Wokugaya Kubalulekile

Eminweni yezinsimbi ziqinile zaseNtshonalanga naseNingizimu ne-Afrika, igolide ivamise ukuboshwa ngokweqiniso ngaphakathi kwamakhala e-quartz noma amagolide e-sulfide. Ukuze uwukhiphe, kufanele ube nemfundiso ye-"Goldilocks Zone" erzomsebenzi wensimbi.

Ubulunga Bokungagqwali Okulinganiselwe: Uma ukuphika kukhulu kakhulu, igolide lihlala libekwe phakathi kwidwala le-host. Izixazululo ze-cyanide noma amanzi obunzimula awakwazi ukunweba noma ukulibamba lokho abangakuthinti.
Ingozi Yokugringwa Okweqile (Imfucu-fucu): Ngakolunye uhlangothi, ukugaya yonke into ibe "umquba" olukhulu oluphakathi, kudala i-slurry ebophayo, enamanzi amaningi. Le mudumba ibopha amaqanda agolide ezitholakalayo, okukwenza ukuba ahlale ephuma phezu namashidi okudonsa, futhi kubangela "ukucwina kwekhabhoni" emithanjeni ye-CIL (Carbon-in-Leach), okubangela ukuthi izithako zakho zingasebenzi.
Isixazululo: Kumele uhloselwe umgomo othile we-P80 (ubukhulu besikrini obuhamba izinto zakho ezingama-80%). Idatha yethu yebala iyakhombisa ukuthi iningi le-Sudanese ne-Ghanaian hard rock, ukufinyelela umgomo onembile we-75-micron (200-mesh) kungakhuphula izinga lokuphulukisa kakhulu.

2. Ukuvala Umsakazo: Imfihlo Yokuxhumana Kwe-Crushing-Ukwenza imihlaba eluhlaza

Ukuze ukhulise ukuphulukiswa kwakho ngo-15%, kufanele uyeke ukwelapha umshini wakho wokuchithwa kanye nebhola lomshini njengemishini ehlukene. Ziyisistimu eyodwa edliwayo ngokuqhubekayo. Nazi izindlela zokulungisa uxhumano oluphukile.

Isinyathelo 1: Maﬁla "Ukudla Okuzoshesha" iMishini Yakho

Hamba uye emazineni amaningi amancane, uzobona umshini omkhulu we-jaw crusher ohlanganisa amatshe angama-40mm kuya ku-50mm ngokuqondile uyawuhambisa ku-ball mill noma ku-wet pan mill. Lokhu kumahlekileyo okukhulu kwezobuchwepheshe bokukhipha insimbi. Imishini yokugaya ihloselwe ukumunca, hhayi ukucindezela. Ukufaka ngamandla amatshe amakhulu kugcizelela ukunciphisa amandla emishini futhi kuqinisekise ukufuthelwa okungalingani.

Ukulungisa: Yengeza izinga lesibili lokugqebha (njengommaki wokugqibela oyingxenye ye-cone noma i-VSI esebenza kahle). Ukuhlanzwe kobukhulu bokudla komshini kusuka ku-50mm kuye phansi kwama-10mm noma ngaphansi kuphatha umsebenzi wezinto zomshini ngamaphesenti angama-30 futhi ngokushesha kukhuphula umthamo wakho wansuku zonke.

Isinyathelo 2: Faka i-Loop Yokuhlonza Evala Evali enguValo Valiwe

Ungathembi kuphela endleleni eyodwa, "evulekile" eholayo nge-mill. Kumele usebenzise uhlelo lokuhlukanisa olusebenzisa i-hydrocyclone noma i-spiral classifier ngokuvala induku ne-mill yakho.

Indlela esebenza ngayo: Umhlukanisi usebenza njengomphathi womnyango. Uqinisekisa ukuthi amathekti "amancane kakhulu" (i-overflow) kuphela ayahambahamba phambili ukuya esigabeni sokutholwa, kuyilapho ngokuzenzekelayo uphoqa amatheki amakhulu agumbelwe kakhulu futhi angakazululeki ukuthi abuyiselwe emshini wokugaya kabusha. Lokhu kususa ngokuphelele incluso inkinga yerhodwe elivaliwe eliphuma ngemfucuza yakho.

3. Ukulinganisa Okuphakeme Ukushayela Ukusebenza Kwe-Cyanidation (Leaching)

Ezindaweni ezinciphisa kakhulu i-cyanidation, usayizi wokokoma uhlela ukunyakaza kwe-chemistry yakho.

Ukususa ngokushesha: Igolide elikhululiwe kahle liyachithwa ngokushesha okukhulu emanzini e-cyanide. Ukudla okungafaki amaphutha kahle kunganciphisa isikhathi sakho sokuhlala kumathangi e-CIL kusuka emahoreni angama-36 waba amahora angama-24, okusindisa izindleko ezinkulu zombane nezibulala-magciwane.
Ukuwohloka komoya kwekhabhoni Uma ugesi wakho ukhiqiza izipheshana eziningi kakhulu (ngokusebenzisa ugesi ongaphezulu), leli klayi luphakamisa i-carbon yakho evuliwe. Le "ukuphushulwa" kuvimbela i-carbon ukuthi ingadonsi ubawusi obekwe phakathi, ikhulisa i-liquid egobile ngokushesha iye emililweni yakho. Uhlelo lokuqukatha oluphuthumayo lokuhlukanisa lusula izipheshana, lugcina i-carbon yakho isebenza kakhulu.

4. Ukuqinisa Ukubuyiswa Kwezikhungo Zenkanyezi

Ubukhazimulisi bonke ubungadingeki ukungena ephathini lamathangi e-cyanide. Igolide elilula ukukholwa kalula kufanele lithathwe masisha lisebenzisa abahlanganisi bemfuyo.

Nokho, abahlanganisi be-gravity balindele isigaba esithile sesayizi samangqamuzana ukuze basebenze kahle. Uma ubafaka isilayidi esingakahlukaniswa, esikhulu, amatye amakhulu azokhonza ngokushesha amantsha amancane egolide aphuma ku-riffles yomhlangano we-concentrator. Ngokusebenzisa isikrini esikhathini esivalelwe ngaphambi komjikelezo we-gravity, uqinisekisa ukuthi ubukhulu be-slurry nobukhulu bamangqamuzana buqondile ngokwezingxenyekazi ukuze uthole amangqamuzana agolide anesisindo.

icala elivela endaweni yase-Obuasi

Kulo nyaka odlule, indawo ephakathi nendawo eduze kwe-Obuasi, e-Ghana, babe sebephakela i-jaw crusher ejwayelekile eya ngqo kumshini omncane, okhiqiza umphumela ongahlehlwanga. Ukubuyiselwa kwabo konke kwaqhubeka ku-65%.

Ngokwethula umshini omncane ochobo lwama-fine crusher futhi balungisa umphakeli wabo ukuze ube uhlelo olungevaleki, bathola ukugoqa okungcono okulingana kwama-micron angu-75.

Umphumela: Kulo nyanga wokuqala, isilinganiso sabo sokululama sakhula saba u-82% sisebenzisa ikhono elifanayo lokucubungula impuphe yomhlaba. Le 17% ukukhuphuka kokukhiqizwa kwegolide nsuku zonke kwakhokhisa zonke izinsiza zokusebenza eziphakanyisiwe zingakapheli izinsuku ezingama-90.

Isipesheli Sobuchwepheshe Mahhala Sabanikazi Bemayini

Ingololwazi yakho yegolide ihlezi embunjini? Ungavumeli inzuzo yakho iwele emgodini wokuphonsa impahla. Thina sihloswe ekusizeni abanikazi bamaminerali eGhana, eSudan, naseTanzania ukuthi Baklame kabusha izindlela zabo zokukhipha kakhulu.
