The way to successfully upgrade a phosphate ore is based on the full understanding of its mineralogy, minerals surface properties, minerals distribution and liberation. the conception of a treatment process consists of choosing the proper operations with an adequate succession depending on the ore properties. usually, froth flotation takes place in phosphate enrichment processes, since it is.
Theoretical and experimental studies have been performed to analyze the flotation processes for recovery of wool wax from an industrial effluent by air flotation. batch flotation process was carried out at different experimental conditions and different air flow rates. the results obtained show that wool wax can be successfully recovered from the tested effluent using batch air.
These units, in a single separation step, can achieve a product recovery and purity equivalent to or even better than that obtained by multistage flotation in conventional flotation cells. hence, in the present work, a flotation column of 1.5 m height and 6.5 cm diameter has been designed and applied in the beneficiation of al-jalamid saudi phosphate ores of the calcareous.
