High Gold Recovery Results from Flotation Test Work at Nalunaq
TORONTO, ON / ACCESSWIRE / July 13, 2020 / AEX Gold Inc. (TSXV:AEX) ("AEX" or the "Corporation") is pleased to provide an update on the results of a recent metallurgical test work program which was aimed at progressing and optimizing the parameters for flotation, following historical test work programs on the Nalunaq Gold Project, in South Greenland.

The MAXGOLD chemistry is a sustainable alternative to the traditionally used sulfide collectors in the flotation of gold. Some benefits of the MAXGOLD product line include: Provide equivalent or superior metallurgical performance at lower doses than traditional collectors. Lower dosage required also translates directly to reduced logistics costs.

Flotation of Gold and Gold-Bearing Ores
Very few gold flotation plants use single collectors, and the preference is either to add a blended collector, that is, a mixture of a number of collectors, or collectors are added separately in smaller quantities than those of the primary collector. These collector combinations result in better overall flotation recoveries.

Recovering Gold through the Froth Flotation Process
Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed into a large tank filled with distilled water.

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides.

Froth flotation
Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Bubbles containing gold and other hydrophilic minerals accumulate at the top of the water level as froth. This froth is then scraped off to create a concentrate of gold and other hydrophilic minerals. Flotation creates high quality concentrates and is good at capturing fine gold.
