How we work · A gravity plant in ten steps

Every plant walks the same ten steps.

Prove the ore, permit the site, let the shaking table decide the circuit. The concrete is poured and the steel erected by BENEFSAN, inside the same offer as the machines, the installation and the water treatment — one responsible party from the drill core to the first concentrate.

Method

Ten stations from a drill core to a running gravity plant

Prove the ore by drilling, permit the site, let the shaking table decide the circuit — then design, pour the concrete, erect the steel, order the machines, install and energise. Ten stations from a drill core to a running gravity plant. Scroll or swipe to walk the line; the arrow keys work too.

  1. Prove

    Station 01 — Core · assay · model

    Drilling proves tonnage and grade before anything is designed.

  2. Prove

    Station 02 — Licence · permits

    Mining licence and site permissions secured up front.

  3. Prove

    Station 03 — Sampling · gravity tests

    The sample runs on the shaking tables at Bursa; the ore shows how it separates.

  4. Design

    Station 04 — Flowsheet · layout

    Test results become a gravity circuit; the circuit lands on the site plan.

  5. Build

    Station 05 — Concrete · steel

    Foundations poured and steel erected by BENEFSAN, inside the same offer.

  6. Order

    Station 06 — Crushing · screening

    The long-lead primary package goes on order first.

  7. Order

    Station 07 — Gravity circuit

    Mills, classifiers and shaking tables — the concentrating heart, per test work.

  8. Order

    Station 08 — Water treatment · tailings

    Thickeners and filters close the process-water loop and dewater the tailings.

  9. Install

    Station 09 — Set · align · pipe

    Machines set, aligned and piped into a single line.

  10. Energise

    Station 10 — Electrics · automation

    Cabled, instrumented, commissioned — handed over running.

Engineering output

The circuit lands on the site plan

Station 04 ends with drawings, not a brochure: the 3D arrangement, the elevations and the IFC package the civil and steel crews build from — all of it inside the BENEFSAN offer.
