01 · The umbrella offer

What is under the roof

BENEFSAN is the umbrella company: the client signs one offer and receives a running gravity plant. Test work, flowsheet, concrete and civil works, steel structure, machines, installation, electrics, water treatment and tailings, commissioning, training and warranty — all under one roof, one responsibility.

Turn-key gravity beneficiation plants

BENEFSAN · One offer · One responsibility

Diagram: one roof, labelled “BENEFSAN — one offer, one responsibility”, spans the eight scopes listed below; every scope hangs from the same roof.

  1. 01

    Test work & flowsheet

    Your sample on the shaking tables at the Bursa test centre; then the flowsheet, mass and water balance and the plant layout.

    You receive
    Test-work report · flowsheet · layout · equipment list
  2. 02

    Civil works & concrete

    Foundations, slabs, terraces and drainage — designed and poured inside the same offer, not left to a separate contractor.

    You receive
    Civil drawings · poured and cured foundations
  3. 03

    Steel structure

    Plant building and equipment structures fabricated, erected and painted to the layout.

    You receive
    Structural drawings · erected steel
  4. 04

    Machines

    Crushing, grinding, classification, shaking tables and dewatering equipment — manufactured or sourced under BENEFSAN responsibility.

    You receive
    Complete machine list, delivered to site
  5. 05

    Installation

    Mechanical erection: machines set, aligned, piped and pumped into a single line.

    You receive
    Installed and aligned circuit
  6. 06

    Electrics & automation

    Motor control centre, cabling, instrumentation and the control room.

    You receive
    Energised plant · control philosophy
  7. 07

    Water treatment & tailings

    Thickening, filtration and clarified water return; dewatered tailings — the loop is closed by design.

    You receive
    Closed water loop · stackable tailings
  8. 08

    Commissioning, training & warranty

    Ramp-up to the guaranteed figures, operator training and a 12–24 month performance warranty.

    You receive
    Plant handed over running · trained operators

Civil works and the steel structure are not left to a separate contractor: the foundations are poured and the steel is erected inside the same offer, and every sub-scope is carried out under BENEFSAN’s responsibility — one responsible party from the foundations to the handover.

02 · Three supporting lines

Around the plant

One offer covers the whole gravity plant. Around it, three supporting lines: test work and flowsheet design, gravity equipment and plant sections, and the reprocessing of tailings and wastes.

02 · Test work & flowsheet

Test work & flowsheet design

Your sample on the shaking tables at the Bursa test centre: gravity response, liberation size, concentrate grade and recovery — then the flowsheet, the mass and water balance and the layout. A package you can build with us or take elsewhere.

Six steps

  1. 01

    Ore characterisation

    Mineralogy, chemical assays, specific gravity of the valuable mineral and the gangue.

  2. 02

    Liberation & comminution tests

    Bond work indices and the size at which the valuable mineral frees itself — the grind the tables need.

  3. 03

    Gravity response

    Shaking-table tests by size fraction; classifier splits.

  4. 04

    Variability programme

    30–60 samples across the resource so the circuit fits the whole deposit, not the average.

  5. 05

    Simulation & balance

    Mass and water balance resolved; table count, terraces and pumps sized.

  6. 06

    Design package

    Flowsheet, layout, equipment list and operating philosophy — ready for civil and steel design.

03 · Gravity equipment

Gravity plant equipment & sections

Shaking tables, hydraulic classifiers, jigs — and the crushing, grinding, dewatering and pumping around them. Single machines, complete plant sections, or a retrofit into an existing plant.

Four supply forms

  1. 01

    Individual machines

    Shaking tables, classifiers, jigs, mills, screens, crushers, thickeners, filter presses, pumps.

  2. 02

    Plant sections

    A crushing circuit, a terrace of tables with its classifiers, a dewatering block — delivered and installed as one unit.

  3. 03

    Brownfield retrofits

    A gravity section added to an existing plant: tie-in design, foundations, steel and installation.

  4. 04

    Wear-part programmes

    Deck surfaces, liners and pump parts scheduled and stocked.

04 · Tailings reprocessing

Tailings & waste reprocessing

Legacy tailings and process wastes through a gravity circuit: recover what still has value, leave a residue as inert and stable as gravity can make it, and recycle the water.

Five steps

  1. 01

    Characterise the dump

    Sampling, assays, size and density distribution of the old tailings or slag.

  2. 02

    Gravity test work

    Shaking tables and jigs at Bursa: how much comes out, how clean the residue gets.

  3. 03

    Reclaim & scrub

    Dump reclaimed, scrubbed and screened — oversize and trash out.

  4. 04

    Classify & concentrate

    Classifier splits feed the tables and jigs; concentrate and metal recovered.

  5. 05

    Dewater & stack

    Residue thickened and filtered to a stackable cake; the water goes back to the plant.
