“…c o m / l o c a t e / h y d r o m e t (Jandová et al, 2010) and china clay in Cornwall, the United Kingdom (Siame and Pascoe, 2011) were tested to extract lithium. Limestone, gypsum and quenched lime were used to liberate lithium from zinnwaldite concentrates via roasting, and Li was then leached using water (Jandová et al, 2009(Jandová et al, , 2010Vu et al, 2013). The concentrates (1.21-1.4 wt.% Li) were first recovered from zinnwaldite wastes (0.21 wt.% Li) using dry magnetic and grain-size separations.…”

“…Each process has its own advantages and disadvantages. For instance, large quantities of residue (8-10 times greater than the original quantity of CFA) are generated during sintering [25]. Moreover, ammonium sulfate sintering also produces toxic gases, such as ammonia.…”

A novel technique was developed for the recovery of lithium and aluminum from coal fly ash using a combination of pre-desilication and an intensified acid leaching process. The main components of the high-aluminum fly ash were found to be Al 2 O 3 and SiO 2 , and the Al/Si ratio increased from 1.0 to 1.5 after desiliconization. The lithium content of the coal fly ash met national recycling standards. The optimal acid leaching conditions, under which the leaching efficiencies of lithium and aluminum were 82.23% and 76.72%, respectively, were as follows: 6 mol/L HCl, 1:20 solid to liquid ratio, 120 • C and 4 h. During the hydrochloric acid pressure leaching process, spherical particles of desilicated fly ash were decomposed into flakes. Part of the mullite phase was dissolved, and most of the glass phase leached into the liquor. The generation of the silicates hindered lithium transport, which decreased the leaching rate of lithium. This work suggests that the preprocessing is a promising option for effective recovery of high-aluminum and fly ash-associated lithium.

Valuable Metals—Recovery Processes, Current Trends, and Recycling Strategies

et al. 2017

View full text Add to dashboard Cite

This Review provides an overview of valuable metals, the supply of which has been classified as critical for Europe. Starting with a description of the current state of the art, novel approaches for their recovery from primary resources are presented as well as recycling processes. The focus lies on developments since 2005. Chemistry strategies which are used in metal recovery are summarized on the basis of the individual types of deposit and mineral. In addition, the economic importance as well as utilization of the metals is outlined.
