This paper designs a square column leaching experiment to probe the coupling flow-reaction-transmission. 2.372 kg of Yanglas copper ore with a grade of 1.25% was loaded in a 6×6 cm2 column whose height is 60 cm. A 28-day leaching gave an approximate copper yield of 14.5 gram, which is an equivalence of copper leaching rate being 50%. Hydraulic conductivity was measured. The changing trends are analyzed by mathematical analysis software Eviews and Matlab, and the numerical simulation was conducted.

Immobilization of lead (Pb) using soil amendments can reduce Pb toxicity and bioavailability in soil. This study evaluated Pb immobilization in a Pb-contaminated soil by using peat moss through various tests. The Pb-contaminated soil (2000 mg Pb·kg−1) was amended with 1%, 5%, and 10% of peat moss to immobilize Pb in the soil. The immobilization properties of Pb in the contaminated soil were evaluated by a column leaching experiment, a microcosm test, and a batch incubation test. Peat moss significantly reduced the Pb leaching in all of the experiments and more effectively reduced mobility and toxicity of Pb in the column leaching and microcosm tests than bioavailability in the batch incubation test. The immobilized lead from the soils amended with 1%, 5%, and 10% of peat moss was 37.9%, 87.1%, and 95.4% from the column leaching test, 18.5%, 90.9%, and 96.4% from the microcosm test, and 2.0%, 36.9%, and 57.9% from the NH4NO3extraction method, respectively, indicating that peat moss can be effectively used for the remediation of Pb-contaminated soil.

A laboratory based column leaching experiment was set up to study the retention of nitrate (NO3- ) and phosphate (PO43-) in three Bangladesh soils (Ghatail, Tejgaon and Sonatola) and their subsequent uptake by plants (Ipomoea aquatica). The investigation showed that the higher the clay contents, the higher was the retention of NO3- and PO43- by the soils and the lesser was their transfer into the growing plants. Again the higher the pH values in soils, the lower was the retention of NO3- and PO43- elements retained in the soils and the higher was the transfer of the elements into the growing plant. Retention of nitrate and phosphate followed the order: Ghatail>Tejgaon> Sonatola while the transfer to plant was in the order Sonatola>Tejgaon>Ghatail. Key Words: Nitrate, Phosphate, Retention, Leaching, Plant Uptake. DOI: 10.3329.bjsir.v43i1.858 Bangladesh J. Sci. Ind. Res. 43(1), 67-76, 2008

Chengde City boasts a wealth of high-quality mineral water resources characterized by a high level of strontium (Sr), a low level of sodium, and low alkalinity. In order to study the mechanism of formation of Sr-bearing mineral water in Chengde and to scientifically guide future mineral water exploration, taking three typical mineral water exploration areas in Chengde as examples, this paper studies the sources of Sr in mineral water and the general rules of its dissolution via a laboratory static leaching experiment and impact experiments, and it provides an analysis of the characteristics of typical rock samples. The research results indicate that the content of Sr in surrounding rock and the characteristics of minerals existing in surrounding rock jointly control the dissolution of Sr in water; that CO2 can promote the formation of mineral water containing Sr; and that temperature increases may boost the dissolution of Sr from carbonate minerals but also inhibit the dissolution of Sr from silicate minerals.
