The flotation of gold bearing ores — A review -
1/7/1994& 0183; Xanthates are normally used on gold flotation plants in conjunction with other collectors promoters to enhance gold recoveries. The recovery of gold is activated by sulphide ions and depressed by ferric ions 13 .
Where to Install a Gravity Concentrator in a Flotation Plant?
Maybe it doesn’t get all the way there and you lose a little bit of gold but that’s a result to a degree of recovery whereas in a flotation cell this is going to be very binary. I mean if this thing sinks you recover zero of it as opposed in a cyanidation plant where maybe you’ve recovered 50% or 70% of the particle before it moves out of the leach train.
Gold Tailings Reprocessing Technology
In general the gold recovery method of gold tailings is mainly the all-slime cyanidation CIP method. It is the recovery of residual gold particles from tailings by using the property of gold soluble in cyanide. The gold recovery for large capacity and low-grade gold tailings is common heap leaching.

1/5/2014& 0183; In porphyry/skarn copper–gold flotation plants gold recovery is often well below copper recovery . With liberated and copper-associated gold readily recovered in the flotation stage this recovery difference is often due in part to operating strategies that require rejection of gold-bearing iron sulphide gangue minerals in order to maintain a saleable copper concentrate grade.
Silver Gold Recovery Flotation Process
The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals the precious metals being incidental constituents and ores in which the gold and silver are of primary importance the base-metal minerals if present being of little or no value. The first class
