ComminutionBateman Engineering designs comminution circuits thattake into account the specific requirements of downstreammetallurgical processes.

CrushingWe have designed and constructed all forms of crushing systemsincluding inpit, primary, secondary, tertiary and quaternarycrushing systems.

Grinding CircuitsOur experience includes the design of large autogenous grinding(AG) and semi-autogenous grinding (SAG) circuits. We haveinstalled a 26 ft (7.0 m) SAG mill at Hartley and have many rodand ball milling references, including Modikwa Platinum and BlueRidge Platinum projects.

Fine GrindingWe have utilised tower mills, stirred mills and ISA mills forflotation concentrate grinding and are experienced in theoperational and maintenance requirements of equipment essentialfor the development of efficient plant designs.

PreconcentrationPhysical separation processes can often be usedprior to flotation to upgrade the flotation feed bymaking use of differences in the physicalproperties of ore and gangue minerals.

Dense-Media Separation (DMS)We have designed and installed DMS plants in thediamond, precious stones, coal, industrial mineral, PGMand zinc industries and pioneered the removal of wastefrom concentrator-feed streams using DMS.

Gravity SeparationOur experience includes the use of spirals to recoverchromite concentrate from PGM flotation feed and theapplication of jigs to recover metal from slag. We havealso investigated the use of centrifugal separators torecover precious metals from milling circuits.

Magnetic SeparationBateman Engineering has been involved in a number ofstudies and projects incorporating the use of magneticseparation in the processing of mineral sands, as well asto concentrate PGM from slow-cooled converter matteinto a magnetic fraction.

Materials HandlingBateman Engineering has the capability to designand supply materials handling systems to transportPGM-bearing ores and tailings.

� All types of conveyor systems to move ore and tailingsto, from and within the processing plant.

� Stockpile systems for the efficient, effective andeconomic stacking, blending and reclaiming of oreand the safe disposal of tailings.

� Plants to process tailings and extract coarse materialfor use as backfill.

FlotationDuring flotation, surface chemistry is applied to selectivelyrecover valuable minerals or gangue materials.

Flash FlotationIn circuits employing multiple stages of milling, flash flotation cellsare used to recover liberated mineral species after each stage toprevent overgrinding.

Conventional FlotationBateman Engineering has many references of plants using banks ofconventional flotation cells and supplies proprietary cells inaddition to providing design and installation services.

Tank CellsBateman Engineering has completed several large tank cellinstallations in recent years.

Column CellsOur experience in the design of flotation circuits includes columnand Jameson cells. This includes the pumping of high air contentfroths associated with fine grinding of concentrates.

Reagent PlantsBateman Engineering has designed and installed numerouspackaged reagent plants, e.g. Impala UG2 plant, Lonmin, AngloPlatinum and Aquarius, either as standalone or as part ofconcentrator plants. Flotation cells, Blue Ridge platinum mine, South Africa.

LeachingHydrometallurgical processes are gradually becomingmore favoured than smelting processes for thetreatment of PGM ore, concentrate and mattes.Bateman Engineering has wide experience of leachingprocesses and designs to process ore, concentrate andsmelter mattes.

Tank LeachingWe have experience of both acid and alkali leach processescarried out in trains of agitated tanks. In this type of plant,selection of materials is critical.

Medium-Pressure LeachingBateman Engineering has a strong process group experiencedin autoclave design. This experience has been used to processhigh-grade sulphide ore, concentrates and converter mattes.

High-Pressure LeachingBateman Engineering has been involved in the design of leachprocesses which utilise titanium-clad autoclaves designed tooperate at 240 °C and 47 bar.

Emerging TechnologiesWe have worked on many projects employing heap leaching,including bacterial heap-leach processes. Several bacterialtank-leach plants have been designed and constructed and wealso have experience of project investigations using variousnovel, proprietary, leach processes, such as the Galvanox™atmospheric leaching process which could potentially beapplied to PGM processing.

Residue and Impurity RemovalThe removal of leach residues and dissolved impuritieswith minimum loss of product is a critical step in mosthydrometallurgical processes.

NeutralisationBetween leaching and the downstream purification processes,it is often necessary to neutralise the slurry or solution leavingthe leach process. This process is often coupled with ironremoval and we have extensive experience of such processesusing a variety of reagents.

Clarifying, Thickening & FiltrationOur experience covers a range of counter-current decantation(CCD), counter-current filtration (CCF) clarifiers, pinned-bedsettlers and sand filters.

Precipitation & CementationEfficient dissolved-impurity removal is essential in mosthydrometallurgical processes. We develop precipitation plantsthat minimise operating cost and maximise metal recovery.

Other ProcessesBateman Engineering has used solvent extraction, ionexchange and molecular recognition technology (MRT) toremove minor impurities from solution streams before routingthe solution to electrowinning circuits. We also haveexperience at designing organic-removal circuits using variousphysical separation processes.

Purification PGMs can be selectively separated by ion exchange (IX)technologies. Bateman Engineering has wideexperience of impurities removal by purification orcementation and classical precipitation techniques.

Ion Exchange (IX)Bateman Engineering provides a one-stop solution combiningseveral IX technologies. Through an exclusive agreement withMintek, traditional fixed-bed or fluidised-bed technology, aswell as the novel resin-in-pulp technology, is available. TheMintek application base combined with a testwork capabilityenhances the delivery of effective process solutions.

Typical applications� Removal of impurities at base metal and zinc refineries.� Copper, cobalt, nickel, and zinc removal from slurries using

resin-in-pulp.� Removal of copper, cobalt and nickel during zinc

purification and copper refining.� Removal of iron from copper electrolytes allowing improved

control of current efficiency in EW circuits.� Resin-in-pulp to replace expensive solid-liquid separations

prior to metal-recovery steps.

RIP systems are used for environmental clean-up to � clean effluent streams and recover trace elements without

the need for costly ultrafine filtration.� clean up effluents from base-metals and PGM refineries.

Metals RecoveryTrace amounts of metal contaminants may be extracted fromlarge volumes of solution flowing at many bed-volumes perminute, often in a form and concentration worth processingfurther.� Copper recovery from in-situ mine-leach solutions and

refinery bleed streams.� Production of cathode-quality copper from acid mine-

drainage streams at high flow-rates.� Iron, aluminium, zinc, copper and manganese recovery

from acid mine-drainage and waste streams.

Solvent ExtractionBATEMAN has a wealth of solvent-extraction (SX) experiencewith SX plants in Australia, Africa and the Americas.

Bateman Reverse-Flow Mixer Settler ®Provides substantial operational and performance benefits over thetraditional mixer-settler design and enables side-by-side orientationof the pump mixers which reduces capital costs and providesimproved operator or maintenance access. The coalescenceenhancement channel and other design aspects provide higherprocess efficiencies and reduced organic loss.

Conventional Mixer SettlersWe also have the capability to design conventional mixer-settlerswith reference plants processing PGMs, copper, cobalt and zinc.

ElectrowinningBateman Engineering designs tankhouses of all sizes, fromsmall heap-leach operations to large scale, automatedsystems for electrowinning (EW) and electrorefining (ER).

Electrolytic CellBateman Engineering’s redesigned cells provide an improvedcatholyte distribution flow pattern around each cathode resulting inimproved cathode quality. The design can also accommodate anodebags and / or a close-capture aerosol / gas emission system, providinga safe working environment.

Tankhouse LayoutOur designs provide low-cost operating facilities for both manual-and automated-strip plants. Attention to detail in materials handlingallows operators to focus on good operational practices that lead toefficient metal production.

Electrowinning, Melting & Casting TechnologyWe have a close relationship with all the suppliers of EW technologyand are able to offer this technology for most refinery projects.

PGM RefiningPGMs are found in nature intimately bound withnickel, copper and iron sulphide minerals. It isnecessary first to separate the PGMs from thebase metals and then to process the individualPGMs (Pt, Pd, Rh, Ir, Ru, Os) as well as gold.

Base-Metal RefiningOur involvement in PGM refining includes the threelargest, primary-platinum refineries in the world, as wellas several smaller plants. We have successfully appliedleaching, SX, IX, MRT, distillation and precipitationtechniques to separate the individual PGMs as well asto remove residual impurities.

Anode Slimes and SecondariesWe have been involved in both pyrometallurgical andhydrometallurgical processes to recover PGMs and goldfrom anode slimes generated in copperelectrorefineries, or from secondary, PGM-bearingmaterials such as autocatalysts or electronic scrap.

Molecular-Recognition Technology (MRT) andstrong-base resin technologyThe MRT technique, similar in some respects to IX, iswidely applicable to PGM refining. Strong-base resintechnology for the removal of Fe from Cu electrolytecan also be provided.

Process ModellingHeat and mass balances that closely simulate plantoperation form the basis of successful plantdevelopment and operation.

Bateman Engineering utilises various simulationprograms to perform front-end modelling of chemicaland physical processes.

Steady State SimulationWe have developed Limn, Metsim® and Pyrosim models for arange of unit operations commonly used in comminution,flotation, hydrometallurgical and pyrometallurgical operationsand also use the JK-SimMet modelling package for examinationof comminution circuits.

Dynamic Simulation SysCAD, the Windows-based package, is used for the dynamicsimulation of processes, Metsim® models transient-operatingconditions, providing upset analysis, surge verification anddownstream de-bottlenecking, and Aspen® simulates complexchemical processes. When interfaced with actual controlhardware, dynamic simulation becomes a time-saving controlsystem for de-bugging and an excellent training tool.

Finite Element Analysis (FEA) and ComputationalFluid Dynamics (CFD)FEA and CFD are applied in the design of furnace componentsand a wide range of other process and mechanical equipment.We can determine the response of structures to loads and theflow characteristics of fluids and gases without the need tobuild and test costly prototypes and conduct lengthy field trials.
