>Flotation of gold and gold-bearing ores
In Brazil, the application of flotation for gold-bearing ores started in the 1980s (Araujo and Peres, 1995). There are three important Brazilian plants using flotation to process gold ores (Monte et al., 2002). At the São Bento plant, gold and pyrite are floated into a bulk concentrate for further processing by bacterial and pressure leaching.
>Gold Extraction Methods From Three Types of Ore
The gold extraction process mainly depends on the chemical composition of the gold ore, the mineral composition, the gold particle size of the gold, and the requirements of the finished product.

Flotation cells are a common ore recovery technique applied in ore and mineral mining operations such as copper and gold. The fotation cell is used to foat ore particles away from the crushed ore/rock mix, by driving air into the bottom of the cell to form bubbles which foat to the top of the main body of liquid to create "froth."
