Ibikoresho bya zahabu byononekara birashobora kugabanywamo ubwoko butatu bwingenzi:
Ubwoko bwa mbere ni arsenic eugh, karubone, na sulfuru ubwoko bwa zahabu. Muri ubu bwoko, ibirimo bya Arsenic birenga 3%, ibirimo bya karubone ni 1-2%, kandi ibirimo sulfuru ni 5-6%. Gukoresha inzira isanzwe ya cyanide ya zahabu, igipimo cya zahabu ni 20-50%, kandi umubare munini wa na2cn. Iyo bikungahaye ku masezerano ya Flotation, nubwo amanota yo hejuru ya zahabu ashobora kuboneka, hakubiyemo ikiganiro cyibanze cyibintu byangiza nka arsenic, karubone, na antimony. Bizagira ingaruka ku ntambwe ikurikira yo gukuramo zahabu.

Ubwoko bwa kabiri ni amabuye ya zahabu arimo zahabu ipfunyitse muri mabuye y'amabuye y'agaciro kandi yangiza umwanda mwiza mu bice byiza n'imiterere microscopique. Muri ubu bwoko, ibirimo icyuma cya sulfide ni gito, nka 1-2%, kandi byinjijwe mu mabuye y'agaciro ya Gasange. Ibice byiza bya zahabu muri konte ya Crystal kuri 20-30%. Gukuramo bya Cyanide cyangwa flotation bikoreshwa mugukuramo zahabu, ariko igipimo cyo gukira cya zahabu kiri hasi cyane.

Ubwoko bwa gatatu ni amabuye ya zahabu hamwe numubano wa hafi hagati ya zahabu, arsenic na sulfuru. Ibiranga nuko arsenic na sufuru ari amabuye y'agaciro nyamukuru ya zahabu, kandi ibintu bya Arseni biraciriritse. Igipimo cyo gushushanya kuri zahabu yubwoko bwubwoko bwa ore ukoresheje inzira imwe ya cyanide ya zahabu iracika intege. Niba zahabu ikungahaye kuri flotation, igipimo cyo hejuru cyo gukira gishobora kuboneka, ariko biragoye kugurisha kuko irimo arsenic ikabije.

tekinoroji yo gucukura amabuye y'agaciro

Guhitamo imiti

1. Amabuye y'agaciro no gutandukana

Uburyo bwa Phoderamati yimiti ya mine ya zahabu ahanini birimo uburyo bwamazi ashyushye hamwe nuburyo bwa Cyanide. Uburyo buvanze ni kera kandi bukwiriye zahabu yoroheje. Ariko, biragoye kandi byarangiye buhoro buhoro ubwenge. Hariho uburyo bubiri bwa cyanidiation, bushishikaza cyanidation na percolation cyanidation.

2. Ibikoresho byo gutoranya imiti no zahabu

Uburyo bwa chimique ikoreshwa muguhitamo ibyatsi bya zahabu, cyane cyane uburyo bwikirere. Ibikoresho byakoreshejwe birimo igikoresho cyo kuvunja kinc, kibange kinguye, nibindi. Igikoresho cyo gusimbuza kinc gisimbuye ibyondo bya zahabu bivuye kuri leachate hamwe nifu ya zinc.

Ikigega cyo kunanirwa nigikoresho cyo kubyutsa agasuzuguro. Iyo ingano ya ore iri munsi ya metero 200 hamwe nigisubizo cyikibazo kiri munsi ya 45%, harashobora gushingwa kugirango yongere kwibanda kuri zahabu yashongeshejwe muri tank yihuta yihuta.
