2019年1月15日 DMS exploits the difference in specific gravity between the target and gangue minerals, and is commonly used in the separation of spodumene from other gangue silicates. The specific gravity of spodumene is between 3.1 and 3.2; this makes it slightly heavier than most gangue minerals such as quartz (2.65), albite (2.60) and muscovite (2.8).

2019年1月30日 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,

2021年3月1日 Abstract Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity separators. Hence, alternative

5 天之前 The role of gold beneficiation reagents cannot be underestimated. More than 85% of the world’s gold ore is mainly extracted by cyanidation. However, the use of a variety of reagents mixed and added into gold beneficiation is mainly to improve the effect of flotation gold selection. Gold beneficiation reagents are important auxiliary materials in mining production, which use
