Gold extraction

Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.

How Is Gold Extracted From Gold Ore? Sciencing

Yet another gold removal process is flotation.The ground ore is put into a solution that contains a frothing agent along with a collecting agent and organic chemicals. The frothing agent turns the solution into a foam. The collecting agent bonds to the gold, creating an oily film that will later attach itself to the surface of air bubbles.

Gold extraction

Overview

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

Gold Extraction and Recovery Processes

Gold Extraction and Recovery Processes

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
