Fraser Alexander provides mining and related services across the entire mining and industrial value chain. Before you’ve even broken soil, we’ve prepared an innovative, customised solution for you and we’re still there once the last ounce of material has been processed. Plus, with over a century of experience, Fraser Alexander remains one of the best in the business.

Mining and remining

Miners at heart

Mining is at the root of Fraser Alexander’s services. As industry specialists, we offer:

Through our trusted partnership with, and equity share in, our opencast mining contractor company, Close-Up Mining, we offer a range of opencast mining services:

  • Removal, load and haul of topsoil, subsoil and overburden
  • Establishment of new box-cuts
  • Drilling and blasting
  • Removal of ore body
  • Loading and hauling from pit to designated stockpiles

Fraser Alexander has executed most of the hydraulic remining projects completed in Africa and South America to date. In fact, our tailings division is where Fraser Alexander originated back in 1912. This extensive experience, and the fact that we process as much as 100 million tons of tailings a year, makes us one of the largest tailings remining companies in the world.

We offer:

Mechanical remining

This is done using a system of mechanical processes, including excavation, screening, sizing, transportation and conveying.

Hydraulic remining

This is the process of using high-pressure water jets to re-pulp the tailings deposits. We use hydro mining units that are manual, remote-controlled, or even (our own innovation) remote-controlled and trackless.

If there’s potential for remining, we’re your experts. Contact us for more information.

Processing

It’s in the process

Fraser Alexander owns, operates and maintains a range of process facilities and can provide you with the metallurgical, engineering and quality management services associated with mineral beneficiation.

We offer end-to-end processes that are tailored to your specific needs. These include breaking, crushing, screening, pelletising, briquetting, mineral processing and integrated water management. Throughput of our plants ranges from 50 to 500 tons per hour and allow modular expansion when configured in parallel or in series.

Our flexible, customisable and cutting-edge processing plant solutions can include all or a combination of:

  • Design
  • Construction
  • Ownership
  • Operation
  • Maintenance


Our packaged DBOOM model (Design, Build, Own, Operate, Maintain) differentiates us by offering a convenient outsourced service that minimises delays and streamlines approvals.

Contact us for more information on how we can assist you with your processing requirements.

 

Moving

Everything moves.

At the heart of many of Fraser Alexander’s solutions are the systems that move the materials between mining sites, processing plants, smelters and disposal sites. As is customary for us, these systems can be customised to your needs and are offered on a DBOOM (Design, Build, Own, Operate, and Maintain) or O&M (Operate and Maintain) basis.

 

We move everything.

Using these systems, the substances we can move range from wet materials (like hydro-remined slurry), through dry materials (like coal, mineral ores and waste), to hot metals. If you need it moved, we can help you using one or a combination of the following solutions:

Wet moving systems:

  • Conditioning, pumping and piping

Dry moving systems:

  • Static, modular and mobile conveyors
  • Bucket elevators
  • Truck dumpers and haulers (articulated and fixed-body)
  • Rapid train-loading systems and wagon tipplers
  • Mobile equipment like loaders, grazers, dozers and compactors

Hot-metal handling:

  • Moving hazardous and hard-to-handle molten material, ingots and hot slag
  • Mobile and semi-mobile equipment and conveyor systems for: breaking, crushing, screening, feeding furnaces, furnace rabbling, train and truck loading, and feedstock logistics management
  • Ladle and slag pot cleaning

 

We move the industry.

Apart from this standard equipment, we also offer several proprietary FA-designed machines to enhance safety and efficiency. These equipment innovations include high-temperature loading buckets, hauler load bodies, and purpose-built trailers with a low centre of gravity.

 

Deposition

Miners at heart

Deposition refers todeposits of bulk materials. It relates to where, what and how we store or dispose of the materials involved in the processes we support. For Fraser Alexander, this deposition coverstailings storage facilities, stockpiles, discard dumps and managing industrial waste.

Mine tailings storage facilities

Tailings management is where Fraser Alexander began in 1912 and it is thanks to this experience that we remain at the forefront of global tailings management. With our well-trained professional team and our proven tailings management systems, we’re able to routinely monitor the 'health' of each facility, intervening proactively whenever necessary.

Stockpiles and dumps

When dealing with huge quantities of raw materials, processed products and waste, it is critical to have safe, effective and environmentally friendly deposition solutions. At Fraser Alexander, we construct, operate and maintain stockpiles and discard dumps, managing everything from the design and footprint, to the environmental effects, fire hazards, and operational safety.

Industrial waste

The element that distinguishes industrial from mining waste management is the fact that each industry and material has its own legal and operational restrictions, and these affect its proper handling and disposal. Some of our typical bulk wastes include power station fly ash and bottom ash, steel industry slags, oils and tars from the synfuels industry, and gypsum from fertilisers.

Rehabilitation

It’s in the process

Mining and industrial processes are, by their nature, disruptive to the environment.These disruptions can impact water quality, vegetation, and even your company’s reputation and bottom line.To circumvent these issues, Fraser Alexander offers a full range of rehabilitation and post-mine-closure solutions. These include:

We’re not a design house, but we do have the skills and experience to know what will support post-closure reform and what won’t. This, along with our integrated project management capability, ensures accurate mine implementation and complex integrated rehab projects.

Through strategic partnerships with agricultural scientists, Fraser Alexander provides site-specific, custom-made and scientifically supported topsoil management solutions that are cost-effective and have been proven to work.

Our traditional strengths in bulk materials handling, bulk earthworks and civil construction also support our rehabilitation projects by offering competencies like:

  • Optimised earth moving that reshapes and develops landforms
  • Placing caps and substrates that support vegetation
  • Establishing vegetation
  • Constructing surface and subsurface water management measures

A rehabilitation solution is only as good as its end results. This is why we offer ongoing monitoring and maintenance of the topsoil and landform functionality. Other land management services offered by Fraser Alexander include:

  • Cutting and bailing of meadows
  • The preparation of fire breaks
  • Erosion repairs
  • Over-seeding
  • Ongoing periodic maintenance, monitoring and reporting

Contact us to discuss how our range of services can support your rehabilitation needs.

Water treatment

A precious resource

Water is a crucial but limited and sometimes costly resource in the mining and industrial industries. This is why Fraser Alexander’s Water Treatment Division has a range of flexible, customisable and modular solutions that manage your water usage, wastage and treatment.

Leading water experts

We can assist with anything from engineering to the construction, procurement, supply, commissioning, operation and maintenance of an FA - or client-owned water treatment facility. Plus, as one of the major driving forces behind Miwatek, the advanced-technology water treatment company, we’re widely considered to be leaders in the industry.

Thorough water services

Our state-of-the-art water treatment applications include:

  • Acid mine/rock drainage (AMD/ARD): Acidic water caused by metal or coal mines
  • Mine impacted water (MIW): Water pollution from mining
  • Influent treatment: Water from dams, rivers or boreholes
  • Effluent treatment: Liquid waste or sewerage
  • Process water treatment: Water used at processing facilities
  • Potable water supply: Water for consumption
  • Wastewater treatment: Environmental water affected by humans
  • Sea water desalination: Removing salt and minerals from sea water
  • Solid/liquid separation technologies: Removing suspended solids from water
