A low grade graphite run-of-mine (r.o.m) ore from eastern India was studied for its amenability to beneficiation by flotation technique. The petrography studies indicate that the ore primarily consists of quartz and graphite with minor quantity of mica. It analyzed 89.89% ash and 8.59% fixed carbon. The ore was crushed in stages followed In beneficiation of graphite by the method of flotation, it has been almost impossible to avoid the entrainment of gangues such as sericite into graphite concentrate. Hence, to solve the aforementioned problem, the use of Nigrosin (C 22 H 16 N 6 O 3 ) as a depressant for graphite in lead-zinc ore processing technology was introduced recently Purification, application and current market trend of natural graphite

XRF results shows that Ningi graphite mineral contains 81.5 wt.% SiO2. It also confirms the presence of ZnO, MnO, and Ni up to 0.055 wt. %. Proximate compositional analysis indicated that NingiA majority of the studied graphite had a distinctly flakey (0.2–1 mm in length) or platy morphology with a well-ordered crystal lattice. Beneficiation studies were performed to produce high-purity graphite concentrate, where rod milling and froth flotation produced a final concentrate of 90% fixed carbon with recoveries between 67% and 83%.Minerals Free Full-Text High-Grade Flake Graphite Deposits in

Improved Flotation of Fine Flake Graphite Using a Modified
Natural graphite ore can be easily purified by froth flotation due to its natural hydrophobicity [3,4,5,6]. Flake graphite exhibits a stronger hydrophobicity and is more floatable than amorphous graphite [7,8,9,10,11,12]. As illustrated in Figure 1, graphite beneficiation generally consists of a multistage grinding and flotation process BENEFICIATION Graphite occurs generally admixed with country rocks, and hence, it requires beneficiation for obtaining desired grade for various end-uses. Processes for graphite beneficiation depend upon nature and association of gangue minerals present.GRAPHITE Indian Minerals Yearbook 2019 IBM

A Mini Review on Flotation Techniques and Reagents Used in Graphite
Since graphite is inherently hydrophobic, flotation is frequently used to beneficiate low-grade ores. The pretreatment process, both conventional and unconventional; liberation/grinding methodsSeparation by froth flotation is an essential beneficiation technique for graphite processing (Chehreh Chelgani et al., 2016). Moreover, due to the flotation-difficulty of cryptocrystalline graphite, the researchers conducted a study on flotation equipment ( Bu, 2018 ), flotation technology ( Bu et al., 2018 ), the treatment of flotation feed ( Wang, Graphite flotation by β-cyclodextrin/kerosene Pickering emulsion
