Leaching behavior of metals from iron tailings under varying pH and low-molecular-weight organic acids

Journal of Hazardous Materials, 2020
The migration of metals (e.g., Fe, Cd, Co, Cr, Cu, Mn, Ni, and Zn) in both of iron tailings under different pH leachates was studied by laboratory static leaching experiments.

Kinetics of leaching: a review

Reviews in chemical engineering, 2020
Kinetics, as a fundamental requirement of nearly all industrial activities and engineering researches, plays a great role in leaching processes. Although there are many pieces of research on its application, there is not a clear pathway for investigating

Global greenhouse vegetable production systems are hotspots of soil N2O emissions and nitrogen leaching: A meta-analysis.

Environmental Pollution, 2020
Vegetable production in greenhouses is often associated with the use of excessive amounts of nitrogen (N) fertilizers, low NUE (15-35%), and high N losses along gaseous and hydrological pathways.

A promising selective recovery process of valuable metals from spent lithium ion batteries via reduction roasting and ammonia leaching.

Journal of Hazardous Materials, 2020
In this study, a promising process has been developed for selective recovery of valuable metals from spent lithium ion batteries (LIBs). First, reduction roasting which used spent anode powder as reduction agent and water immersion are applied to ...

Research progress on leaching technology and theory of weathered crust elution-deposited rare earth ore

Hydrometallurgy, 2020
Rare earth (RE) with specific application value has become the relatively important strategic resource for all countries. Weathered crust elution-deposited rare earth ore (WCED-REO) are rich in middle-heavy RE, and its exploitation restrict the global ...

Review of leaching behavior of municipal solid waste incineration (MSWI) ash.

Science of the Total Environment, 2019
Incineration is widely adopted in modern waste management because it provides an effective way to minimize municipal solid waste that needs to be disposed of in landfills. The ash residue is often disposed by landfilling.

Organic inputs to reduce nitrogen export via leaching and runoff: A global meta-analysis.

Environmental Pollution, 2021
Organic inputs as a substitution for, or addition to, chemical fertilizers can potentially mitigate N losses. However, it is not well known how their effects on N leaching and runoff depend on application approaches.
