Nickel Stabilization Efficiency of Aluminate and Ferrite Spinels and Their Leaching Behavior

Environmental Science & Technology, 2006
Stabilization efficiencies of spinel-based construction ceramics incorporating simulated nickel-laden waste sludge were evaluated and the leaching behavior of products investigated. To simulate the process of immobilization, nickel oxide was mixed alternatively with gamma-alumina, kaolinite, and hematite. These tailoring precursors are commonly used to

A clean and efficient leaching process for chromite ore

Minerals Engineering, 2014
In order to improve the chromate salts cleaner production technology, a pressure leaching process for chromite ore in 50 wt% KOH solution was studied for the first time and the results were presented in this manuscript. It was found out that the chromium extraction rate increased significantly with the increase of temperature and oxygen partial ...

Hydrodynamic and leaching efficiency comparison of horizontal and vertical well Systems in Uranium in-Situ Leaching

Journal of Contaminant Hydrology
Vertical wells are predominantly used for both injection and extraction in uranium in-Situ leaching (ISL), yet they often produce uneven spreading of leaching solution and relatively low leaching efficiency. Horizontal wells, widely applied in oil and shale-gas operations, offer a plausible alternative for solution injection, but their suitability for ...

Energy efficient routing in multi-level LEACH for WSNs

2015 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2015
Energy efficient routing is the paramount point of significance in any wireless sensor network (WSN) so that the network sustains without any human intervention. Various energy efficient protocols have been proposed, multi-level Low Energy Adaptive Clustering Hierarchy (LEACH) being one among these.

Effect of Irigation Efficiencies on Nitrogen Leaching Losses

Journal of Irrigation and Drainage Engineering, 1985
The literature was reviewed to determine the effect increasing irrigation efficiencies have had on NO3-N leaching. The mass of NO3-N leached is directly related to the drainage volume. By increasing irrigation efficiencies, both the drainage volume and amount of NO3-N leaching are reduced.

An Energy Efficient Algrithm Based on LEACH Protocol

2012 International Conference on Computer Science and Electronics Engineering, 2012
In this paper, we analyse the effectiveness of LEACH protocol in extending the lifetime for energy-constrained wireless sensor networks. An improved protocol LEACH-R is proposed based on LEACH protocol. LEACH-R improves the selection of cluster-head and proposes to choose relaying node compare to LEACH. Residual energy of the nodes is conisdered during

High-efficiency leaching process for selective leaching of lithium from spent lithium iron phosphate

Waste Management
With the arrival of the scrapping wave of lithium iron phosphate (LiFePO4) batteries, a green and effective solution for recycling these waste batteries is urgently required. Reasonable recycling of spent LiFePO4 (SLFP) batteries is critical for resource recovery and environmental preservation.

Development of an Efficient Irrigation and Leaching Control System

2015 ASABE International Meeting, 2015
Abstract. The LSU Irrigation and Leaching Control System was designed to reduce irrigation consumption and nutrient leaching during containerized plant production. Recent work has 1) integrated wireless tipping bucket sensors into the system, and 2) tested the system at an ornamental nursery production facility to document reduced irrigation and ...
