Copper Recovery from Printed Circuit Boards Using Acidic Ferric Chloride Leaching and Electrodeposition
(Springer, 2020-06)
In this work, 0.5 mol L−1 HCl and 0.13 mol L−1 FeCl3 have been used as leaching solution of industrially wasted copper at room temperature. Copper recovery from the leaching solution has been studied by batch electrodeposition ...
Biocatalysed acidification and metal leaching processes in sediments of polluted urban streams
(Inderscience Enterprises, 2014-04)
Sediments of fluvial streams are a sink for pollutants such as heavy metals and organic recalcitrant compounds. In anoxic conditions, sulphide generation and alkalinisation cause precipitation of heavy metals. The redox ...
Nitrate Leaching in an Argiudoll Cultivated with Sugarcane
(2014-09)
The aim of the study was to quantify nitrate leaching from an Aquic Argiudoll cultivated with sugarcane in Tucumán, Argentina. Two field trials were conducted during the 2010/2011 and 2011/2012 seasons with the variety LCP ...
Actinobacteria isolated from mineral ores in Peru
(Faculty of Biotechnology and Food Sciences in Nitra, 2018)
A total of twenty-four isolates of actinobacteria from arsenopyrite, pyrite, polymetallic sulfides and magnetite from Peruvian mining zones have been used with the purpose of characterizing them by morphological, physiological ...

Nitrogen Leaching Of Spring Wheat Genotypes (Triticum Aestivum L.) Varying In Nitrogen-Related Traits
(Taylor & Francis, 2014-05)
Efficient use of nitrogen (N) by wheat crop and hence prevention of possible contamination of ground and surface waters by nitrates has aroused environmental concerns. The present study was conducted in drainage lysimeters ...
