Hydrometallurgy

Hydrometallurgy and high-purity materials

Lithium compounds, high-purity alumina, titanium dioxide, vanadium products and high-purity silicon involve different production routes. They share important engineering tasks: managing acids and reagents, cleaning off-gas, treating effluent and recovering useful by-products.

Diovis supports plant layout and process integration, bringing these systems together with the requirements of the production process.

What we deliver

Technical support for materials projects

We agree the scope around your project stage, from an initial feasibility assessment to plant layout and process integration. Each assignment defines the required inputs and deliverables.

Feasibility assessment

Review of the proposed process, available information and project requirements. The assessment identifies the technical questions and data gaps to resolve, with a preliminary cost estimate based on the agreed scope.

Material and energy balances

Balances that connect the main process with reagent consumption, utilities and by-product streams. These provide a basis for evaluating integration options and resource requirements.

Plant layout and process integration

Layout development and coordination of the connections between process stages, equipment and supporting systems, taking account of operating needs and product purity requirements.

Environmental process integration

Recommendations for acid and reagent management, off-gas cleaning and effluent treatment, considered alongside the production process. We assess opportunities to recover useful components from by-product streams.

Results for the next project stage

Depending on the agreed scope, the deliverables include a technical assessment, balances, a layout concept, integration recommendations and a preliminary cost estimate. Open technical questions and the information needed for the next stage are stated clearly.

Battery recycling

Battery recycling and materials recovery

Spent batteries are a source of recoverable materials. The metals available for recovery and the appropriate processing route depend on the battery chemistry and the composition of the incoming material.

Relevant experience includes contributions to the basic design of a multi-chemistry battery recycling plant, with a separate process chain for each battery type.

Battery chemistries covered

Li-ionLi-SOCl₂NiCdNiMHAlkaline

For battery recycling projects, we address reagent handling, off-gas cleaning and effluent treatment as part of the overall plant layout and integration.
