Recycling of Cu powder from industrial sludge by combined acid leaching, chemical exchange and ferrite process.
A method in combination of acid leaching, chemical exchange and ferrite process was applied to recycle copper and confer higher chemical stability to the sludge generated from etching process in printed circuit board industry. Ninety-five percent copper could be recycled in the form of powder from the sludge. Moreover, not only the wastewater after chemical exchange can be treated to fulfill th...
متن کاملLeaching of heavy metal from native plants by chemical leachants
Plant biomass harvested after heavy-metal phytoremediation must be considered as a hazardous waste that should be contained or treated appropriately before disposal or reuse. This study provides an evaluation of extractants for the removal of lead from Abutilon Theophrastus biomass. The research was carried out a leaching study to determine the lead-extraction efficiency of the different leacha...
متن کاملAlkali Leaching of Indian Coal for Ash Reduction
Coal is a major source of energy. The available Indian coal quality is very poor having very high ash content and low calorific value. Indian coal generates a large quantity of ash as a by-product of combustion. The objectives of the present study were to reduce the ash content of coal to produce ultra-clean coal. The coal was treated wi...
متن کاملExtraction of Lithium from Lepidolite Using Mixed Grinding with Sodium Sulfide Followed by Water Leaching
Mixed grinding with Na2S followed by water leaching was performed to extract Li from lepidolite. The leachability of Li increases dramatically in the ground mixture, regardless of the mixing ratio over the range of 1:1 to 3:1, while only 4.53% of Li was extracted in lepidolite ground without Na2S. The leachability increased with an increase of the grinding time, and ultimately, 93% of the Li wa...
متن کاملA High-temperature Powder Diffraction Furnace
A new high-temperature XRD instrument, utilizing multilayer optics and a custom furnace, has been developed to maximize sensitivity and minimize problems associated with sample displacement. This paper will describe the technical specifications of the new instrument, and will present temperature calibration with standard reference materials and measurement of phase evolution in an industrial gl...
