study of spent refractory waste recycling from metal
Characterization and recycling of spent refractory wastes
Feb 01 1999 · The two largest waste streams (responsible for nearly 50 of the spent refractory landfilled in Missouri) were chosen for characterization and recycling studies because of the potential to lead to major reductions in the amount landfilled.

Reduction-ammoniacal leaching to recycle lithium cobalt
It is therefore essential to develop a sustainable closed-loop recycling technology (reduction-ammoniacal method) for spent LIBs. In this study the effects of various species of ammonia ammonium salts and reductants on the leaching of Li Co Ni Mn and Al from spent LIBs were investigated with a hydrothermal method.
