Immobilization of Zn, Cu, and Pb in contaminated soils,

30-05-2009· Considerable research has been done on P-induced Pb immobilization in Pb-contaminated soils. However, application of P to soils contaminated with multiple heavy metals is limited. The present study examined effectiveness of phosphoric acid (PA) and/or phosphate rock (PR) in immobilizing Pb, Cu, and Zn in two contaminated soils.rock phosphate cu zn pb and grinding - thepennefather,Phosphate rock has the highest affinity for Pb followed by Cu and Zn with Abstract. The solid-liquid interface reaction between phosphate rock (PR) and metals (Pb Cu and Zn)was studied. Phosphate rock has the highest affinity for Pb followed by Cu and Zn with sorption capacities of 131 114 and 83.2 mmol kg-1 PR respectively.

Phosphate Rock - an overview | ScienceDirect Topics

Phosphate rock of 70 to 75% BPL, or as high as is reasonably obtainable, is finely ground in a ball mill and then mixed with cooled recycled phosphoric acid-gypsum slurry in a digestion tank (Figs. 10.3 and 10.4).At this stage the only reaction which occurs is between acid and any carbonates present in the rock, and between phosphates and low concentrations of sulfuric acid which may be,Heavy metal pollution from phosphate rock used for the,,01-01-2009· Composition of phosphate rock largely depends on its type and origin. Sedimentary rocks contain high concentration of heavy elements: U, Th, REE (rare earth elements) , etc. along with environment polluting elements: Cd, As, Sb, V, Cr, Zn, Cu, Ni, etc.The amounts of these hazardous elements vary widely not only among various phosphate rock sources but also even in the sameExtremely High Phosphate Sorption Capacity in Cu-Pb-Zn,,Introduction.
