long axis. The graphite in the raw ore sample was a flake-, scale-, or plate-like structure. The particle size of graphite was small, mostly between 0.05 and 0.25 mm. Most particles were scattered and unevenly present in the gaps between muscovite and quartz, and some parts were slightly concen-trated. The graphite in the ore sample appeared

PURIFICATION OF FLOTATION GRAPHITE BY ALKALI …
Since there are fewer naturally occurring high-grade graphite ores, low-grade ores must be processed to increase their value to meet the rising demand, which is predicted to increase by >700% by 2025 due to the adoption of electric vehicles. Since graphite is inherently hydrophobic, flotation is frequently used to beneficiate low-grade ores.

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 pressure and bacterial leaching ...

Flotation Techniques in Graphite Processing: Separating Graphite …
2. Importance of Flotation in Graphite Processing. Flotation plays a crucial role in graphite processing as it enables the separation of graphite from various impurities. Graphite ores often contain minerals such as quartz, mica, feldspar, and other carbonaceous materials, which need to be separated to obtain high-purity graphite.
