Copper and Brass are indispensible base materials for today's industry. Due to high market demand, commodity prices are rising. Tin as an essential ressource for many industry branches already underlies heavy competition as it becomes more and more scarce. Strategic supply risks are foreseeable due to increasing political instability, trade barriers and arising distributional conflicts.
Detinning of stamping plant scrap or in-house production scrap of wire, sheet or rod can be a solution to secure the supply of the own smelting work demand.
A positive side effect of chemical detinning is the opportunity to regain the tin through a chemical treatment process.
The outcome is TIN GRAIN - a high-purity Tin(IV) Oxide granulate with a tin content of up to 70 %.
