Mineraçãomethod for removal of phosphorus from iron ore Among the tested acids, sul-furic acid is the most effective for this purpose The leaching time is low (~20 minutes) and the iron loss is negligible (less than 025%) Zhang and Muhammad (1989) used nitric acid to remove phosphorus from the iron ore of the Kiruna region, Sweden...know more

Phosphorus RemovalPhosphorus removal from wastewater can be achieved either through chemical removal, involving the addition of calcium (lime), iron (ferric chloride) and aluminium salts (aluminium polychloride), advanced biological treatment, involving heterotrophic bacteria, called polyphosphate accumulating organisms (PAO) or a combination of both...know more

Froth Flotation of Iron OresWith the depletion of high grade iron ore, the removal of alumina containing minerals and phosphorous from low grade iron ore has received increasing attention in iron ore industry The flotation behaviour of kaolinite was found to be opposite to that of quartz and special care has to be taken for the successful removal of the clay mineral...know more

Nitrogen and Phosphorus Removal ,Sep 22, 2014· The nitrogen and phosphorus removal in the bioreactor packed with cedar chips and iron continued until approximately 500 days of operation, but the removal decreased significantly after that period In contrast, the nitrogen and phosphorus removal in the bioreactor packed with aspen wood and iron continued over 1200 days of operation...know more
