Zhang and Muhammad (1989) used nitric acid to remove phosphorus from the iron ore of the Kiruna region, Sweden. A concentrate of sinter, moist, and without treatment was used. Chemical analysis showed the composition of 0.98% phosphorus (as P 2O 5 22.25%) and 60.85% iron.

Removal of phosphorus from iron ores by chemical leaching

Removal of phosphorus from iron ores by chemical leaching

Removal of phosphorus from iron ores by chemical leaching. Abstract. Alkalileaching and acidleaching were proposed for the dephosphorization of Changde iron ore, which contains an average of 1.12% for phosphorus content. Sodium hydroxide, sulfuriced, hydrochloric and nitric acids were used for the preparation of leach solutions.

Phosphorous removal from wastewater Lenntech

Phosphorous removal from wastewater Controlling phosphorous discharged from municipal and industrial wastewater treatment plants is a key factor in preventing eutrophication of surface waters. Phosphorous is one of the major nutrients contributing in the increased eutrophication of lakes and natural waters.

REMOVAL OF SULFUR AND PHOSPHOROUS FROM IRON ORE

REMOVAL OF SULFUR AND PHOSPHOROUS FROM IRON ORE

Removal of sulfur and phosphorous from iron ore concentrate by leaching 849. Effect of temperature. Since temperature may affect the rate of chemical reactions, the effect of temperature on the leaching efficiency was investigated.

Remove phosphorous via waste water treatment, sodium </h2>Chemical Reaction and RemovalIn nature pure elemental phosphorus is rare. It usually exists as both inorganic and organic phosphate originating from various natural and human sources (fertilizer, livestock waste, outdated sewage/septic systems, cleaning products). High levels of phosphorus and other nutrients, such as nitrogen, can create harmful water quality conditions. Both are essential nutrients for aquatic plant growth. However, when said nutrients are available in excess a body of water can become eutrophic or
