Tailings & Secondary Resources
Recovery of valuable and critical elements from mine tailings, process residues and selected secondary metal-bearing streams.
BASE METALS & CRITICAL MATERIALS PROCESSING
Yekan Sang Tandis processes primary and secondary metal-bearing materials through hydrometallurgical and pyrometallurgical routes — recovering valuable metals and producing industrial compounds, intermediates and refined product forms.
FEEDSTOCKS
We work across mineral feedstocks, secondary resources and selected spent-battery streams, with the process route defined by composition, target recovery and required product form.
Recovery of valuable and critical elements from mine tailings, process residues and selected secondary metal-bearing streams.
Processing of base-metal ores, concentrates and mixed mineral feedstocks toward specified compounds, intermediates or metal products.
Processing selected battery chemistries and battery-derived materials to recover zinc, manganese, nickel, lithium, cobalt-bearing and other valuable fractions.
PRODUCT FAMILIES
Commercial product forms span base-metal compounds, recovered metal products and critical-material intermediates. Exact specifications are confirmed per inquiry and batch.
Zinc-bearing feedstocks and recovered zinc streams converted into industrial oxide, sulfate, carbonate and metal product forms.
Manganese-bearing ores, battery-derived fractions and process streams converted into manganese compounds and industrial product forms.
Copper-bearing concentrates and secondary streams processed toward metal, sulfate, oxide and qualified intermediate forms.
Nickel-bearing mineral and battery-derived streams processed toward sulfate, oxide, metal-bearing intermediates and nickel–copper sulfide products.
Lithium-bearing battery and secondary streams processed toward carbonate and qualified lithium-bearing intermediates.
Recovery and conversion of potassium-bearing process streams into industrial salts and selected product forms.
Targeted recovery of valuable, critical and rare elements from tailings, complex residues and battery-derived feedstocks.
PROCESSING TECHNOLOGY
The processing platform combines hydrometallurgical and pyrometallurgical routes to separate, concentrate, convert and recover valuable components from diverse metal-bearing materials.
