Core Capabilities

Nine integrated service lines.

From a first investigation to a verified result on your plant, with test work and implementation under one roof.

SERVICE 01

Metallurgical & Process Consulting

We diagnose what your plant is really doing and why, then tell you how to fix it, backed by data.

Plant surveys, metallurgical accounting, mass balances and process diagnostics
Flotation, comminution, classification, screening, gravity separation and dewatering investigations
Grade, recovery, yield, throughput and reagent-consumption performance reviews
Sampling campaigns, test-work planning, data interpretation and technical reporting
Root-cause investigations for unstable production, off-spec product, poor recovery and water-quality effects

SERVICE 02

Process Design & Engineering Support

From concept to a workable, buildable design that suits your ore, your site and your budget.

Concept development, process flow sheets, process descriptions and design-basis support
Equipment sizing & selection for pumps, flotation cells, mills, screens, cyclones, filters, tanks and mixers
P&ID philosophy, operating philosophies, control narratives and interlock requirements
Brownfield modification concepts, plant-layout support, tie-in planning and constructability input
Technical scopes of work, equipment specifications, vendor evaluations and execution support

SERVICE 03

Commissioning, Ramp-up & Stabilisation

We get new and modified circuits running to design intent, safely and on schedule.

Commissioning plans, readiness reviews, punch-list support and start-up sequencing
Wet commissioning, process proving, operating-window development and ramp-up support
Performance testing against design intent and agreed operating targets
Operator coaching, operating procedures, troubleshooting guides and handover documentation
Post-commissioning optimisation and close-out of process-related defects

SERVICE 04

Optimisation & Debottlenecking

Find the constraint, remove it, and prove the gain holds under normal plant conditions.

Identification of throughput constraints and bottlenecks across the circuit
Equipment duty checks, residence-time reviews, pumping and screening/classification efficiency
Reagent optimisation, froth and mass-pull control, product-quality stabilisation and recovery improvement
Operating-window definition and practical action plans ranked by impact, cost and ease
Follow-up trials to confirm the improvement is sustainable

SERVICE 05

Specialised Flotation Reagents & Chemistry

Reagent blends developed for the ores conventional suites struggle with.

Development and manufacture of specialised flotation reagent blends for challenging ores
Solutions for oxidised, weathered, fine and difficult-to-float material
Collector, activator, modifier, frother and process-aid development, tailored to your mineralogy
Laboratory screening, dosage optimisation, compatibility testing and plant-trial support
Technical support on performance, consumption, selectivity and froth behaviour

SERVICE 06

Metallurgical Laboratory Equipment Supply

Equip your lab or pilot plant from a single technical supplier who understands the work.

Batch flotation machines and flotation-cell accessories
Laboratory ball mills, grinding media and small-scale comminution equipment
Filter presses, vacuum filtration accessories and dewatering equipment
Wet screening units, test sieves, sieve shakers and ultrafine grinding mills
Rotary and riffle sample splitters, sample-prep equipment, fans, pumps, tanks, scales and consumables

SERVICE 07

Industrial Chemicals, Lubricants & Raw Materials

Reliable supply of the chemicals and lubricants your plant runs on, through a single channel.

Manufacture and supply of industrial grease and application-specific lubricating products
Heavy-duty grease removers, degreasers and equipment-cleaning chemicals
Process chemicals, commodity chemicals and formulation raw materials
Chemical sourcing and consolidation for multiple products from a single supplier

SERVICE 08

Mining & Rock-Drill Equipment Support

Rock-drill equipment, spares and machinery support for surface and underground operations.

Rock-drill equipment, spares, drill accessories and consumables
Drill rods, bits, couplings, shanks, hoses, lubricants and wear components
Machinery inspection, repair, refurbishment and return-to-service support
General mine and plant engineering spares sourced to specification

SERVICE 09

Fabrication, Installation & General Engineering

Practical steelwork and site engineering that turns the design into installed plant.

Fabrication of tanks, chutes, launders, pipe supports, platforms, walkways, guards and steelwork
Piping modifications, equipment installation support and mechanical fitment
Shutdown and maintenance support and small brownfield modifications
General supply of goods, engineering consumables and competent project labour
