Abstract :Chromium production is widespread globally and effective management of its waste materials is critically important due to the significant environmental and health risks posed by improper disposal. Türkiye, with around 2,000 active chromite deposits, is one of the leading chromium producers in worldwide. Chromite is primarily used in the metallurgy, chemical, and refractory industries, and its resistance to corrosion makes it valuable in the automotive, aerospace, and machinery sectors. Its enrichment in platinum group elements (PGEs)—such as osmium, ruthenium, iridium, rhodium, palladium, and platinum —adds further economic value, as do associated minerals like olivine and serpentine commonly found in chromite deposits. Despite its economic potential, improper handling of chrome ore residues presents serious environmental threats, including water and soil contamination and air pollution. These issues are often worsened by the presence of toxic heavy metals, including PGEs. To mitigate these impacts, there is growing interest in utilizing chrome residues as secondary raw materials. Recovering valuable components from these wastes not only reduces environmental hazards but also contributes to more sustainable resource use. This study reviews both global and local efforts aimed at reclaiming chromium from mining residues. It highlights the importance of developing efficient recovery processes and expanding their application across Türkiye. Promoting such practices is essential for environmental protection and offers considerable economic benefits. The main goal is to support the advancement of sustainable chromium recovery, ensuring both ecological preservation and improved resource efficiency.
