  A review of the beneficiation of calcareous phosphate ores …

  201061 · Abstract The beneficiation of phosphate ores containing carbonate gangue by conventional techniques such as physical separation methods or flotation is very difficult due to the similarities in physico-chemical properties of constituent minerals present in the system. Carbonate-rich phosphate deposits can be processed by calcination and by …

  Flotation Application of Cationic and Mixed Anionic …

  20231129 · As a common means of mineral separation, flotation is widely used in the beneficiation of various ores. The floatability of minerals is closely related to the wettability and surface electrical properties of the mineral [ 4 ]. In nature, in addition to a few minerals such as graphite, sulfur, and other minerals having good natural floatability.

  202241 · However, processing these ores has proven difficult and uneconomical due to high serpentine (>50 wt%) and low pentlandite (<5 wt%) content [4]. Serpentine (Mg 3 Si 2 O 5 (OH) 4) is a phyllosilicate mineral composed of a 1:1 arrangement of tetrahedral silica and octahedral brucite (Mg (OH) 2) sheets, held together by weak van der Waals forces [4].

  Attempts at the beneficiation of lateritic nickel ore

  198751 · This effect can be attributed to the increase in electronegativity at the edge of magnesium hydroxide octahedral layer of phyllosilicate (serpentine). DISCUSSION - POSSIBILITY OF THE BENEFICIATION OF LATERITIC NICKEL ORE Ni content was determined by electron-probe microanalysis for some min- eral species.
