FEEDSTOCKS

Primary minerals. Secondary resources. Spent batteries.

The value of a recovery process starts with understanding the feedstock. Yekan Sang Tandis evaluates material composition, target elements, impurities and downstream product requirements before defining the processing route.

Tailings & Secondary Resources

Recovery of valuable and critical elements from mine tailings, process residues and selected secondary metal-bearing streams.

TYPICAL FEED

Mine and beneficiation tailingsProcess residues and filter cakesSelected metal-bearing industrial residuesMixed secondary mineral resources

PROCESSING TARGETS

Base-metal recoveryCritical / rare element concentrationImpurity separationConversion to saleable intermediates

Ores & Concentrates

Processing of base-metal ores, concentrates and mixed mineral feedstocks toward specified compounds, intermediates or metal products.

TYPICAL FEED

Manganese-bearing oresCopper / nickel-bearing concentratesZinc-bearing mineral feedMixed base-metal concentrates

PROCESSING TARGETS

Upgrade and purificationSelective metal separationCompound productionMetal / intermediate production

Spent Batteries & Battery Materials

Processing selected battery chemistries and battery-derived materials to recover zinc, manganese, nickel, lithium, cobalt-bearing and other valuable fractions.

TYPICAL FEED

Alkaline batteriesZinc-carbon batteriesLi-ion: NMC / NCA / LCO / LMO / LFPNiMH and selected primary-lithium systems

PROCESSING TARGETS

Zn / Mn recoveryNi / Li / Co-bearing recoveryBlack-mass and intermediate processingSeparation of reusable mineral fractions

Feedstock acceptance is technical, not generic.

Different sources require different pretreatment, separation and recovery routes. Commercial acceptance is therefore confirmed after review of representative analysis, sample or batch data.
