On the progression of leaching from large particles in heaps [PDF]

, 2012
Includes bibliographical references.Although heap leaching is by now a well-established technology choice in the mining industry, the process remains limited by low recoveries and long extraction times.

Phosphorus leaching as influenced by animal manure and catch crops [PDF]

, 2013
Leaching of phosphorus (P) constitutes an important part of P losses from Swedish agricultural soils. Phosphorus leaching is complex and is influenced by many factors, from source and mobilisation to transport pathways, as well as agricultural management

Techniques in detect selective leaching in metal components

Brazilian Journal of Radiation Sciences
Selective leaching is a corrosion type in, in which certain element in an alloy is preferentially removed from a material, leaving behind a porous or weakened material that can affect its quality and structural integrity.

Extraction of metals from saprolitic laterite ore through pressure hydrochloric-acid selective leaching

, 2015
In this study, pressure hydrochloric-add selective leaching was used to leach Ni and Co from saprolitic laterite ore on the basis of potential-pH diagrams constructed for Fe-Si-Cl-H2O and Ni-Si-Cl-H2O systems. The leaching of Ni, Co, Mg, Mn, and Fe was

Selective leaching of Mo from an off-grade gravity lead concentrate in Na2CO3 solution [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2019
The selective leaching of Mo from an off-grade gravity lead concentrate was investigated in Na2CO3 solution using air as an oxidant. The leaching behaviors of Mo and Pb were predicted by the thermodynamic phase diagrams of Pb-Mo-C-H2O system.

Nitrogen leaching in small agricultural catchments [PDF]

, 2004
Nitrogen (N) leaching from arable land to the aquatic environment is considered a serious problem. Small agricultural monitoring catchments in Sweden were used for the application and testing of model-based methods for quantification of N leaching from ...

Catch crop strategy and nitrate leaching following grazed grass-clover [PDF]

, 2007
Cultivation of grassland presents a high risk of nitrate leaching. This study aimed to determine if leaching could be reduced by growing spring barley (Hordeum vulgare L.) as a green crop for silage with undersown Italian ryegrass (Lolium multiflorum Lam.)

Management affects nitrate leaching from organic farms [PDF]

, 2013
Management decisions significantly affect nitrate-N leaching (N-leaching) from comparable organic fields. The main concern is field management during autumn and themanagement of grass leys.

Inorganic-organic hybrids originating from organosilane anchored onto leached vermiculite [PDF]

Materials Research, 2013
The reactivity of clay minerals leached in grafting reactions was investigated. Precursor solids were prepared by treating the sodium vermiculites with nitric acid solutions at several concentrations.
