Iron Species and Gangue Mineralogy Mapping - Core Scan

linked to our ability to accurately identify not only ple species of iron oxide minerals, but also sub-species, phases (eg. ochreous vs. hard) and associated gangue minerologies. Beneficiation of iron ore is ultimately guided by this inherent mineralogy as well as secondary properties such as grain size, impurities and grindability.

Mar 15, 2019 · The ore contains magnetite and low-density gangue minerals. During classification in the hydrocyclone, the particle size and density affected the classification. In this particular case, the feed to the TowerMill circuit was below 1 mm, and there were high chances where these particles were in the liberated form, i.e. high-density magnetite and ...

Use of phosphate rocks for sustainable agriculture - fao

Computerized image analysis can be useful in estimating phosphate grain or gangue mineral sizes. While the phosphate grains and gangue mineral grains may occur in some rocks as distinct particles, some rocks contain significant amounts of gangue minerals occluded within phosphate particles. Cement-particle relationships are also important.
