Considering the current situation in phosphate ore beneficiation both home and abroad, the new trend of processing technology and reagents in China are summarized. Flotation is still regarded as the main processing method in phosphate ore beneficiation for a certain time in near future.
ABSTRACT. More than two-thirds of coal in China is present in dry areas and cannot be separated by traditional wet coal preparation techniques. Dry coal beneficiation is an effective technique to realize coal separation and upgradation, as it does not consume water, has a low cost and is pollution-free.
The lunar is rich in iron (Fe), titanium (Ti), chromium (Cr) and aluminum (Al) and other mineral resources. At present, in situ resource utilization (ISRU) is the most effective way to develop and utilize lunar mineral resources, and mineral processing is the key step of in situ resource utilization. However, the traditional mineral processing technology is not …
The objective of beneficiation is to remove the noncoal mineral matter from the coal to provide a consistent quality with improved calorific value and reduced ash content in the cleaned coal. Coal beneficiation 4 can be divided into two groups: physical and chemical beneficiations. In physical the beneficiation process, ash forming mineral matter and …
