Kinetics of cupric leaching of pyrite in 4 M NaCl solutions Cinétique de la lixiviation cuivrique de la pyrite dans des solutions de NaCl 4M
(Taylor & Francis, 2020)
Cupric chloride leaching is an attractive alternative for the treatment of pyritic refractory gold ores. In this context, the kinetics of pyrite dissolution was studied in cupric chloride solutions containing 4 M NaCl. ...
The mechanism of 234U 238U activity ratio enhancement in karstic limestone groundwater
(Elsevier B.V., 1993-01-05)
Experimental etch/leach of Carboniferous Limestone gravels on a laboratory time-scale has demonstrated that 234U 238U activity ratios (AR's) greater than the radiochemical equilibrium value may be generated on short ...
Physical and chemical transformations of gangue materials during leaching of copper sulphides, and their influence on copper leaching kinetics
(South African Institute of Mining and Metallurgy, 2017)
© The Southern African Institute of Mining and Metallurgy, 2017. This work reports preliminary results from investigations of the chemical and physical transformations of gangue materials during ferric leaching of a copper ...
Ionic speciation and risks associated with agricultural use of industrial biosolid applied in Inceptisol
(Springer, 2019-07-01)
The evaluation of the chemical leaching potential from soils amended with biosolid is of extreme importance for environmental safety of agricultural use of these residues. The objective of this study was to evaluate the ...
Leaching of Ni and Cu from mine wastes (tailings and slags) using acid solutions and A. ferrooxidans
(2009-12-28)
The objective of this work is to evaluate the acidic and biological leaching of tailings containing Ni/Cu from a flotation and smelting plant. Acidithiobacillus ferrooxidans, strain LR, was used for bioleaching at pH 1.8 ...
