Greenfield & brownfield

Two Ways into a Plant

A new plant is settled on test data before capital is committed. An existing plant starts with measurement, not a proposal — the constraint is found before anything is bought.

Greenfield Project

From Concept to Commissioning. From Feed to Value.

We develop integrated process and engineering solutions for new industrial plants, starting with feed characterisation and technology selection and progressing through plant design, project implementation and commissioning. Every critical decision is driven by process performance, technical feasibility and project economics.

  1. Feed Characterisation & TestworkEvaluate feed properties, composition and variability to establish process requirements, recovery potential and product objectives.
  2. Process Development & Technology SelectionDevelop process flowsheets, mass balances and equipment concepts to identify the most suitable technical solution.
  3. Feasibility, Basic Engineering & CAPEXEstablish plant configuration, utility requirements, preliminary equipment specifications, capital cost estimates and project feasibility.
  4. Detailed Engineering & DesignTranslate the selected process into coordinated engineering deliverables covering plant layout, mechanical, structural, piping, electrical and instrumentation interfaces, with 3D modelling where applicable.
  5. Procurement & Project ImplementationSupport equipment procurement, technical bid evaluation, vendor coordination, construction interfaces and project execution.
  6. Commissioning, Performance Testing & Ramp-UpSupport plant commissioning, process stabilisation, performance evaluation and ramp-up towards agreed operating and product specifications.
Brownfield Modification

An Existing Plant That Isn't Meeting Its Numbers

We improve the performance of operating plants through plant audits, debottlenecking and modification engineering, from the first circuit survey to shutdown execution and post-upgrade verification. The work starts as a measurement exercise, not a proposal — the constraint is found before anything is bought.

  1. Plant Audit & Circuit SurveyReview the operating plant, its equipment and its records to establish actual throughput, recovery, product quality and downtime against design.
  2. Mass Balance ReconciliationSample and measure the circuit to build a reconciled mass and water balance that shows where material, value and capacity are being lost.
  3. Bottleneck IdentificationPinpoint the equipment, transfer points and process steps that limit capacity, recovery or reliability, and quantify the gain from removing each one.
  4. Modification & Retrofit DesignEngineer the changes to fit the existing layout, structures and utilities, from equipment replacement to circuit reconfiguration and new transfer arrangements.
  5. Shutdown-Window PlanningSequence fabrication, installation and tie-ins so that the work fits planned shutdowns and keeps lost production to a minimum.
  6. Post-Upgrade VerificationMeasure the modified plant against the agreed targets for throughput, recovery and product quality, and support the stabilisation of the new operation.

Engineering the Journey from Resource to Value

Every KGS project follows one connected path, from understanding the feed material to creating lasting value on the plant. Each stage is engineered with the next in mind, so that process, recovery and product decisions work together.

Feed

Understand the Resource

We start by understanding the feed material, its composition, mineralogy and variability. This establishes the basis for selecting the right process, assessing recovery potential and evaluating project feasibility.

Scope at this stage
  • Feed characterisation
  • Sampling and assay
  • Mineralogy
  • Variability assessment
  • Recoverable-value assessment

One engineering partner. From process concept to project execution.
