Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, and classification etc., but the advantage is only partial removal of adhered …
Graphite is an important industrial mineral. Two types occur in nature, crystalline and amorphus. Crystalline graphite is used principally for crucibles and shaped structures. …

Yingdong Du [75] used kerosene as a collector, 2# oil as a ing agent, and sodium silicate as an inhibitor in the flotation test of a flake graphite ore in Inner Mongolia. After one roughing, two scavengings, one rough concentrate regrinding, and five cleanings, the obtained concentrate grades and recovery were 90.5 % and 90.05% ...
China is the largest exporter of crystalline graphite and graphite products globally (Jara et al., 2019, Li et al., 2019), and more than 50% of flaky graphite reserves in China are deposited in the northeast regions, such as Luobei and Jixi. One striking feature in these high-latitude areas is the occurrence of freeze–thaw (F-T) weathering ...
Although graphite is flexible, it is not elastic and has high electrical and thermal conductivity. It is also chemically inert and highly refractory. Since graphite displays low …
Graphite is an important non-metallic mineral resource, an allotrope of carbon. Graphite is black-gray, soft, greasy, chemically stable, corrosion-resistant, and does not react easily …

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, …
