Gold Gravity Separation Process Introduction
Generally , that includes grinding , screening , des-liming and
grading , grinding and screening are processes to grind the pulp
with gold and screen the gross gravel which without gold , the main
equipment are round screener and vibrate screener etc .
Zhengzhou Hengyang use desling as process to wash away the fine
pulp that will influence the grinding , the main equipment include
different specification of des-liming hoppers , to separate
gulch-gold , The separation of gold is usually a combination of
several gravity equipment , like chute, jigger , pulsating chute ,
spiral classifier , shaking table , centrifugal separator and cone
separator etc .
Gulch-gold separation divides into gold dredger and fix ore washer.
Many experiences show that : de-ironing separator + jigger +
shaking table + concentrate box with inclined tube , this
integration system has the high recovery , stable operation ,
jigger install normally between ball mill and classifier as rough
separation equipment , ball mill spigot transport to jigger , the
heavy mineral separated transport to shaking table for re-screen ,
the light mineral auto flow to classifier . Finally , the gold brut
grade could reach 40-45%,that could be smelting directly pur gold .
In this disposition , jigger reflect “ recycle as soon as possible
“, that is in favor of gravity process and recovery , centrifugal
machine and shaking table this disposition is widely applicated in
gold dressing plant .
