“…It is a ubiquitous element, which occurs at a pretty low level (Rahman and Singh 2019). Lead has been used in industry, household products, cigarettes, ceramic glazes, paint, smelters, televisions, pesticides, computer monitors, batteries, explosives, pipes and toys for centuries (Sanz et al 2022). Because it can result in significant environmental contamination and health issues, lead is the most significant toxic heavy metal in the environment (Aliasgharpour2020).…”

One of the most unfortunate attributes of technology’s routine and widespread use of most of the elements in the periodic table is the abysmal functional recycling rates that result from the complexity of modern technology and the rudimentary technological state of the recycling industry. In this work, we demonstrate that the vast profusion of alloys, and the complexities and miniaturization of modern electronics, render functional recycling almost impossible. This situation is particularly true of “spice metals”: metals employed at very low concentrations to realize modest performance improvements in advanced alloys or complex electronics such as smartphones or laptops. Here, we present a formal definition of spice metals and explore the significant challenges that product design decisions impose on the recycling industry. We thereby identify nine spice metals: scandium (Sc), vanadium (V), gallium (Ga), arsenic (As), niobium (Nb), antimony (Sb), tellurium (Te), erbium (Er), and hafnium (Hf). These metals are considered fundamental for the properties they provide, yet they are rarely recycled. Their routine use poses severe problems for the implementation of closed material loops and the circular economy. Based on the data and discussions in this paper, we recommend that spice metals be employed only where their use will result in a highly significant improvement, and that product designers place a strong emphasis on enabling the functional recycling of these metals after their first use.

“…It is extensively distributed in rocks, soils, and other unconsolidated sediments on the Earth's surface and serves as a fundamental constituent of igneous, metamorphic, and sedimentary rocks. From an economic perspective, the majority of feldspar extraction occurs from granites (Heyes et al, 2012;Sanz et al, 2022). Its structure, comprising aluminum, silicon, and oxygen atoms, results in the formation of a stable tetrahedral lattice architecture (Yang et al, 2014).…”

The present study investigates the effects and mechanisms of aluminum (Al(III)) and iron (Fe(III)) ions on the flotation efficiency of potassium feldspar (K-feldspar) within oleate collector systems. The study employs micro-flotation experiments, solution chemistry calculations, zeta potential measurements, and FT-IR and XPS analyses to demonstrate that Al(III) and Fe(III) ions can significantly improve the flotation recovery of K-feldspar by altering its surface charge, bonding properties, and adsorption modes. The study also develops adsorption models for the flotation of K-feldspar activated by Al(III) and Fe(III), revealing the synergistic impacts of metal ion hydrolysis products and sodium oleate in the formation of hydrophobic complexes.
