We are the world’s leading technology partner for sustainable metal recovery

We provide low cost, environmentally sustainable biorefineries for recovering valuable metals from a range of waste materials.

From trash to treasure

Gold

Primary source: E-waste
1 Ton Circuit Board = US$12,000

Copper

Primary source: E-waste
1 Ton Circuit Board = US$2,000

Platinum

Primary source: Auto cats
1 Ton Catalytic Converter = US$33,000

Cobalt

Primary source: Lithium-Ion Batteries
1 Ton LiCo Batteries = US$23,000

Palladium

Primary source: Auto cats
1 ton catalytic converter = US$200,000

Lithium

Demand for recycled lithium projected to increase exponentially through rapid EV adoption

A deep dive into the mint process

STEP 1

Receive material and prepare for product recovery

Upon receipt, waste material weighed and milled to a sand consistency to enable rapid metal recovery.

STEP 2

Multistep extraction process

Precious metals including gold, palladium and platinum dissolved using Mint’s proprietary chemistry. Other metals such as copper are recovered using a conventional electrochemical process.

STEP 3

Used chemicals recycled

Precious metals selectively recovered from solutions using Mint’s patented biosorption process. Barren leach liquors recycled for further processing.

STEP 4

Product refining

Extracted precious metals refined to pure metal for immediate sale. Upon recovery, the feedstock supplier receives payment for all recycled metals.

We're different

Low cost

Mint’s low cost metal recovery plants improve payment times and profitability for recyclers providing a truly circular solution.

Low carbon

Mint metals such as gold, palladium, copper, cobalt and lithium are produced with ultra low carbon emissions for a sustainable future.

Local

Mint’s scalable biorefinery plants recover valuable metals from waste streams, powering local circular supply chains.

Mint biofinery deployment process

STEP 1

Plant acquired in desired location

Target waste stream(s) identified in a city or location of interest and biorefinery specifications (size, cost, deployment time etc) agreed with the customer. Customer (or partner) can select plant deployment commercial model.

STEP 2

Plant build and handover

Mint designs and builds plant in customers chosen locations. The plant is handed over to customer/partner following commissioning and training of the local team.

STEP 3

Continuous metal recovery

The mint process is fast and clean - optimally configured to recover metals from 5-25 tons of waste material per day. Long term technology license is provided based on metal recovery volumes.
