Chizindikiro cha Golide

Chizindikiro cha Golide

Zogulitsa zagolide zagolide zimatha kugawidwa m'mitundu itatu yayikulu:
Mtundu woyamba ndi wambiri arsenic, kaboni, ndi sulufure lembani golide. Mu mtundu uwu, zopangidwa ndi arsenic ndizoposa 3%, zokhudzana ndi kaboni ndi 1-2%, ndipo zokhala ndi sulufure ndi 5-6%. Kugwiritsa ntchito njira yachilengedwe ya cyanide, chinsinsi cha golide chimakhala 20-50%, ndipo kuchuluka kwa na2cn kumatha. Mukakhala ndi ukadaulo wamalingaliro, ngakhale kuti malo okwera kwambiri a golide akhoza kupezeka, okhazikika amakhala ndi zinthu zambiri zovulaza monga arsenic, kaboni, ndi anti-anti. Zidzakhudza gawo lotsatira la golide.

Mtundu wachiwiri ndi ored okhala ndi golide womwe golide umakulungidwa m'michere ya gangae ndi zosafunikira pazigawo zabwino ndi ma microscopic mitundu. Mu mtundu uwu, zokhumba za chitsulo ndizochepa, pafupifupi 1-2%, ndipo zimaphatikizidwa mu michere ya gangae. Tinthu tating'onoting'ono tagolide mu nkhani ya makristal kwa 20-30%. Njira zachikhalidwe za cyanide kapena njira zopindulitsa zopindulitsa zimagwiritsidwa ntchito pochotsa golide, koma chiwombacho chimakhala chotsika kwambiri.

Mtundu wachitatu ndi ore golide wokhala ndi ubale wapamtima pakati pa golide, arsenic ndi sulufule. Khalidwe lake ndi la arsenic ndi sulufu ndiye chonyamula mchere wa golide, ndipo arsenic zokhala ndi zapakatikati. Dongosolo la golide lokhalo la mtundu uwu la ore pogwiritsa ntchito mtundu wina wagolide wa ku cyanade ndi wotsika kwambiri. Ngati golide walemedwa ndi maluwa, kuchuluka kwa chiletso chapamwamba kumatha kupezeka, koma ndizovuta kugulitsa chifukwa zili ndi arsenatic kwambiri.

UTHENGA WABWINO

Kusankha kwamankhwala

1. Kugonera golide ndi kupatukana

Njira zopindulira zamankhwala zamigodi zamagolide zimaphatikizapo njira yotentha yamadzi ndi njira ya cyanside. Njira yosakanikirana ndi yokalamba komanso yoyenera golide wobiriwira. Komabe, ndikuyipitsidwa pang'onopang'ono ndipo wasinthidwa mwanzeru ndi nzeru. Pali njira ziwiri zakumiseche, zosokonezana zosokoneza ndi kuzungulira kwa chipongwe.

2. Zida zosankha zagolide

Njira ya mankhwala imagwiritsidwa ntchito kusankha mafuta agolide, makamaka njira yamlengalenga. Zipangizo zomwe zimagwiritsidwa ntchito zimaphatikizanso chipangizo cha zinc ufa, zotupa zolimbitsa thupi, zina za zinc. Zida za zinc.

Thank yosangalatsa yosangalatsa ndi chipangizo cholimbikitsira kusalala. Pamene tinthu tating'onoting'ono tapansi pa ma mesh ndi njira yothetsera mavuto omwe ali m'munsi 45%, kuyimitsidwa kumatha kupangidwa kuti awonjezere kuchuluka kwa golide wosungunuka ndikuthandizira nthawi yoyambira.
