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.

Pb Immobilization

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.

Three woody landscape species, Rhododendron indica ‘President Clay’, Ligustrum sinense ‘variegata’, and Ilex crenata ‘compacta’, were grown in media prepared from fresh pine bark, pine bark with wood, and pine tree chips. Although media were variable in physical properties, all exhibited very high hydraulic conductivity and low water holding capacity. The capacity of these media materials to hold fertilizer elements was very low. Nitrogen, potassium, and phosphorus were rapidly removed by leaching while calciuum and magnesium were retained longer because of the low solubility of dolomitic limestone. Pine bark was the best growth media tested for all plant species. Pine bark with wood was less satisfactory than pine bark and growth was poorest in pine tree chips. More research is needed on the use of the organic amendments with greater amounts of wood before being widely used as organic components of growth media.
