GOLD RECOVERY OF REFRACTORY SULFIDE CONCENTRATES
GOLD RECOVERY OF REFRACTORY SULFIDE CONCENTRATES

in gold recovery the objective of this study is figuring out the effect of sodium nitrite as an oxidizing reagent on cyanidation of refractory gold ore. Cyanide leaching of the concentrate was performed at 20 w/w of solid 500 gram of refractory sulfide gold ore concentrate in a 2.5 liter glass reactor with aeration and stirred at 250 rpm.

Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. However, froth flotation processes may also be used to concentrate the gold. In some cases, particularly when the gold is present in the ore as discrete coarse particles, a gravity concentrate can be directly smeltedto for
