Founded in 2011. Corporate Office in Texas.
CoreX’s globally patented process enables coal ash and residual
slag fines to be upgraded into more valuable co-products.
CoreX produces PCC and fine aggregates.
PCC is Precipitated Calcium Carbonate:
a manufactured mineral with high
performance and cost-saving benefits
for diverse manufacturers with a
$4B global market
Fine aggregate is a component in Portland
cement concrete and other construction
applications

Executive Summary
Precipitated Calcium Carbonate
“PCC”
• PCC is the fastest growing component of the functional filler
minerals segment
• PCC exhibits superior particle shapes and size distributions
when compared to alternatives such as talc, kaolin, titanium
dioxide, or ground calcium carbonate
•World PCC market doubled in 10 years to 17 million tons in 2012
and is expected to grow at a CAGR of 3.9% though 2019
•Filler grade CaCO3 (both PCC and GCC) > 76 million tons in
2012
•PCC price ranges: $150/ton for pulp/paper - $1,500/ton for
pharma
4. Pulp Paper – Whiter, brighter, better ink absorption
Extruded Plastics (PVC) – stiffness, strength
Injected Plastics –flowability, fire resistance
Adhesives –viscosity
Coatings – pigment base extender
Rubber – abrasion resistance, stiffness
Water Treatment – corrosion control, remineralization
Pharmaceuticals – mild abrasive, tablet delivery, anti-acid
Food – mineral fortification, animal feed
Air Emissions – acid rain prevention
Oil & Gas - well drilling fluid, proppant

The Corex Clean Manufacturing Process
Produces PCC at 80% Lower Cost
7. We convert coal ash and slag into useful materials
Two feedstocks - Coal ash or Steel slag and CO2
Two products - Precipitated Calcium Carbonate (PCC)
- Fine cement aggregate or formed goods
Advantages for coal ash & slag management
• Low Energy - Ambient Temperature/Pressure
• Low Cost - Catalytic
• High Throughput
• Clean manufacturing processes
• Reduce ash & slag inventory
• Direct emissions reductions

Limestone supports Steel and Power Production
CoreX separates lime from the ash and/or slag and then
adds CO2 to produce PCC
