Heal legacy damage

ENVIRONMENTAL IMPACT

Two Paths. One Mission. Zero Compromise.

Extraction That Restores

The Cleanup That Pays for Itself

Across Appalachia and former coal regions worldwide, mountains of culm and rivers of acid mine drainage represent decades of environmental damage. Traditional cleanup is costly with no return. Stratacore transforms this equation.

From Waste to Worth

Five pathways to environmental recovery

Bioleaching

Zero chemicals. Self-sustaining. Minimal energy.

Rare Earth ElementsLithiumGalliumAluminum

Controlled Acid Leaching

Contained system. Closed-loop. Revenue from pollution.

GalliumGermaniumLithiumRare Earth Elements

Physical Separation

No chemicals. No water. Carbon captured.

High-grade carbonMagnetic mineralsHeavy mineral sandsDense REE minerals

Flash Joule Heating

Converts waste to graphene. Destroys pollutants.

GrapheneTurbostratic carbonVolatilized Li/Ga/Ge

Plasma Treatment

Unlocks unprocessable materials. Kentucky-proven.

Fire Clay REEsRefractory mineralsComplex oxide matrices

Energy Economics Matter

Right method. Right location. Right power source.

Bioleaching

Very Low

Ambient temp. Self-sustaining.

Ideal - minimal grid dependency

Physical Separation

Low

Gravity & magnets. Minimal power.

Excellent - can operate on intermittent power

Controlled Acid Leaching

Low-Medium

Heating + pumping. Moderate needs.

Good - thermal storage can buffer intermittency

Flash Joule Heating

Medium

High power, milliseconds only.

Good - can schedule around peak renewable availability

Plasma Treatment

High

Continuous high-temp plasma.

Requires baseload or storage; ideal near hydro/nuclear

Smart Matching

Digital Twin assigns each zone to its optimal recovery method—matching material value to energy cost.

Culm Bank Remediation Workflow

From damaged landscape to productive land

1

SCAN

Stratacore drone fleet maps entire culm bank

  • Hyperspectral identifies REE/Li/Ga concentration
  • LiDAR calculates precise volumes
  • Magnetics reveal internal structure
2

MODEL

Digital Twin creates comprehensive 3D block model

  • AI classifies "pay zones" vs inert waste
  • Extraction sequence optimized
  • Processing pathway assigned per zone
3

EXTRACT

Surgical removal targets high-value zones only

  • Minimizes total material movement
  • Feeds directly to processing
  • Low-grade material undisturbed
4

PROCESS

Matched processing for each material stream

  • Bioleaching for REE-rich zones
  • Physical separation for carbon
  • Flash Joule for graphene
5

RESTORE

Site returned to productive condition

  • Material regraded and stabilized
  • Native vegetation reestablished
  • Water quality monitoring confirms success

Healing the Watershed

Acid mine drainage is among the most persistent forms of water pollution on Earth. When sulfide minerals contact air and water, they generate sulfuric acid that mobilizes heavy metals. This process continues for centuries without intervention.
