An optimal laboratory two-step procedure was developed for sodium/potassium O-alkyl
carbonodithioate (sodium/potassium alkyl xanthates) production in the form of aqueous solutions.
Sodium isopropyl xanthate (Na-iPrX), as the most effective salt in a real ore flotation process, was
also produced at an industrial level and introduced as a collector for copper ores. In order to reduce
toxicity of the flotation process and improve sustainability by minimising environmental impacts,
collector efficiency and selectivity in the flotation process were studied in relation to possible synergism
of xanthates combined with the derived biomass and biodegradable green reagents levulinic acid,
5-hydroxymethyl-2-furanacrylic acid (HMFA), and condensation product of hydroxymethylfurfural
and levulinic acid. Optimal content of 30% of HMFA in the collector pointed to the possibility of
substitution of commercial xanthate collector without significantly affecting its efficiency/selectivity.
The ...density functional theory (DFT) calculations provided insights into the interaction mechanism
of Na-iPrX and HMFA with cooper. The benefits of the presented method highlight production
simplicity, mild reaction conditions, high purity and yield of products, no by-products, and
technological applicability on an industrial scale.
