Processing routes for complex metal feeds.

Processing routes for complex metal feeds.

Re-2Ox develops hydrometallurgical processing routes for complex metal-bearing materials. We bring together feed characteristics, buyer requirements and processing economics to define a route toward saleable products.

FEED · BUYER · ECONOMICS

We choose the product around the feed.

Impurities, complex mineralogy and treatment costs can limit the value a material owner receives. Re-2Ox focuses on applications where a dedicated recovery route could improve the commercial outcome.

SUPPLY AN EXISTING REFINERY

Produce an intermediate that meets the refinery’s requirements, with the route assessed against recovery, treatment charges and full delivered cost.

REFINE FURTHER

Continue to a more refined product where the additional saleable value justifies the extra processing, capital and operating cost.

How far to process is a commercial decision.

Feed chemistry, buyer specifications, reagent use, residue management and full delivered cost determine the route.

TECHNICAL FOUNDATION

A technical foundation to build on.

PRODUCT MADE

Cobalt sulphate produced in SGS testwork, 2018.

ENGINEERING

Preliminary demonstration design prepared by SGS.

NEXT PROGRAMME

Selected-feed qualification and a costed demonstration.

THE PROCESSING OPPORTUNITY

More value from material already mined.

Mines, plants and refineries generate concentrates, intermediates and residues whose value can be constrained by impurities or processing complexity. Re-2Ox is developing recovery routes for selected materials where the technical and commercial case can be established.

The objective is a product a buyer can use, at a processing cost the material can support.

THE DEVELOPMENT APPROACH

From feed assessment to deployment.

Oxidation and selective recovery are configured around the material and intended product. Each application progresses through defined technical and commercial decisions.

SCREEN

Review assays, mineralogy, buyer requirements and current economics.

QUALIFY

Define recovery, product quality, reagent use and residue pathways.

DEPLOY

Develop the operating, infrastructure and commercial arrangements for a qualified application.

DEPLOY

Develop the operating, infrastructure and commercial arrangements for a qualified application.

Our current focus is the first application, the independent qualification work it requires, and a costed demonstration programme.

PROCESS KNOWLEDGE

Each campaign strengthens the process knowledge.

Testwork builds understanding of feed behaviour, operating conditions, recovery and product quality. That knowledge guides the next application and the engineering needed for deployment.

DEVELOPMENT MODEL

First operation. Then wider deployment.

Our development model starts with an operation established with project partners. Subsequent expansion is planned through licensing and technical support for customer-financed operations.

Build the operating reference. Apply the knowledge across further sites.

PLANNED DEVELOPMENT — first application, demonstration and subsequent licensing.

COBALT, ONTARIO

Mining country shaped the mission.

Re-2Ox began with a place that knows both sides of mining: the value it creates and the work it leaves behind. The purpose is to recover more value from material already mined while reducing the liabilities that keep difficult streams out of the market.

Recover value. Reduce liability. Leave it better.

Discuss a processing challenge.

Discuss a processing challenge.

Start with the material, the current processing or sales constraint, and the outcome you need. Available information can start the conversation; confidentiality and sample requirements can follow.
