process of preparing the low-grade phosphate ore for obtaining the phosphate concentrate using the flotation concentration. The apatite concentrates are obtained using the selective flotation from the silicate and oxide minerals while defining the process of selective flotation of apatite from carbonate deposits is the major problem worldwide.
The enrichment of the low-grade-phosphate ore of the Tozeur-Nefta deposit was investigated using scrubbing-attrition, ball grinding and anionic/cationic reverse flotation in order to separate phosphate-rich particles from their gangue. The choice of the beneficiation process was based on the petrographic, mineralogical and chemical analyses.
· The process used to extract gold is largely dependent upon the ore deposit and the mineralogy of the ore. A flotation process is one method used throughout the industry to recover gold. It''s a very cost-effective method for concentrating gold, and is a desirable process …
· The froth flotation process has transformed some low-grade ore deposits that were previously considered unexploitable into deposits of industrial value, solved the problem of recovery of useful components in many fine ore grains, made it easy to obtain high-grade and high-recovery concentrate, and made reasonable and full use of mineral resources.
· 2 Flotation Processes of 4 types of associated fluorite. Just as is the case with almost ore processing and non-metal beneficiation, the concentrate fluorite is extracted by crushing, sieving, grinding, grading, flotation, filtration, drying, etc. How to realize the high-efficiency sorting of associated fluorite ore is a real problem in the ...
