The Urban Alchemist

Mastering Hydrometallurgical Extraction from Electronic Waste

The world’s richest mines aren’t underground—they are in our landfills.

Strategic Objectives

• Master low-temperature chemical extraction techniques for maximum purity.

• Reduce environmental impact by bypassing high-heat pyrometallurgy.

• Identify and recover high-value Rare Earth Elements and precious metals.

• Implement scalable, sustainable urban mining operations in any setting.

The Core Challenge

Traditional smelting is energy-intensive and toxic, while millions of tons of precious metals remain locked in discarded electronics.
