A Combined Method of Leaching and Co

A novel recycling process of spent LiNi0.6Co0.2Mn0.2O2 cathode materials has been developed. The process comprises acid leaching followed by regeneration of LiNi0.6Co0.2Mn0.2O2 materials with carbonate co-precipitation. Spent LiNi0.6Co0.2Mn0.2O2 materials were effectively leached in sulfuric acid and hydrogen peroxide solution. The leaching efficiencies were 97.8% for Li, 98.1% for Ni, 96.5%

It is the key to ensuring the economic benefit of the concentrator to choose the appropriate percolation leaching

Process for recycling mixed-cathode materials from

A "grave-to-cradle" process for the recycling of spent mixed-cathode materials (LiCoO 2, LiCo 1/3 Ni 1/3 Mn 1/3 O 2, and LiMn 2 O 4) has been proposed.The process comprises an acid leaching followed by the resynthesis of a cathode material from the resulting leachate.

Systematic Approach to Determination of Maximum

2019-12-12  Accelerated carbonation of basic oxygen furnace slag (BOFS) coupled with cold-rolling wastewater (CRW) was performed in a rotating packed bed (RPB) as a promising process for both CO2 fixation and wastewater treatment. The maximum achievable capture capacity (MACC) via leaching and carbonation processes for BOFS in an RPB was systematically determined throughout this study. The leaching

Leaching processes, however, are not limited to such ores. The chlorination process, which is obsolete by now, used chlorine gas that was

The Problem of Leaching Pesticide Environmental

Leaching is the movement of contaminants, such as water-soluble pesticides or fertilizers, carried by water downward through permeable soils. Generally speaking, most pesticides adsorb to soil particles (especially clay), become immobile, and do not leach. The fate of mobile pesticides, however, can be thought of as a race between the various degradation processes and leaching to groundwater.
