Flotation of Gold and Gold-Bearing Ores - ScienceDirect

Jan 01, 2016  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 pressure and bacterial leaching (the latter is currently on care and maintenance).

Sep 13, 2017  It’s a very cost-effective method for concentrating gold, and is a desirable process used for the upgrading of low-sulphide and refractory ore for further gold recovery treatment. Froth flotation is a process used to selectively separate hydrophobic materials from hydrophilic materials.

Gold extraction - Wikipedia

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.

Sep 01, 2001  Keywords Gold ores; precious metal ores; froth flotation INTRODUCTION Recovery of native gold and electrum from gold ores and base metal ores is an important industrial practice. General methods used, alone or in combination, include gravity concentration, flotation, and cyanidation.

Froth flotation - Wikipedia

Principle of operation. Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains.This process is known as liberation.The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required.
