Project Admiral Bay Lead-Zinc Concentrator Process Plant Study, Western Australia


Project Overview

RSV-Australia approached Sargon Engineering with the purpose of completing an engineering study for the implementation of a mine and concentrator plant at Admiral-Bay, Western Australia, with the end client being Kagara Resources. To complete this work, RSV-Australia would plan and engineer the mine and site infrastructure with Sargon Engineering carrying out the process design and preparing layouts for the concentrator plant. Sargon Engineering’s scope also included the completion of a +/- 30% cost estimate for capital expenditure, as well as operating costs.

Solutions Delivered

Upon receipt of metallurgical testwork results, Sargon Engineering completed process flow diagrams & stream-tables for the following areas:

  • Stockpiling
  • Secondary & Tertiary Crushing
  • Primary & Secondary Ball Milling
  • Lead Flotation
  • Zinc Flotation
  • Lead Concentrate Thickening & Filtration
  • Zinc Concentrate Thickening & Filtration
  • Tailings Thickening
  • Pastefill Plant
  • Lead Concentrate Loadout
  • Zinc Concentrate Loadout
  • Reagents Supply
  • All Plant Utilities
  • Tailings Storage

Sargon Engineering developed a plant layout showing the spatial requirements for the plant areas listed above.

Sargon Engineering sized and estimated costs for all major mechanical equipment, considering shop and on-site fabrication, transportation to site & installation.

Part of the project’s direct capital cost was estimated by multiplying the combined cost of installed
mechanical equipment by scrutinised factors to account for:

  • Site Preparation
  • Site Improvements
  • Piping
  • Instrumentation
  • Electrical Works
  • Painting
  • Paving
  • Proratables
  • Commissioning

Concrete and structural steel were estimated by multiplying installed unit rates by material takeoff results based on Sargon Engineering’s conceptual CAD model of the reclaim stockpile area and
process plant.

The operating cost estimate was generated from reagent, consumable, and maintenance rates calculated from Admiral Bay METSIM model data.

Notable Results

Sargon Engineering delivered this tightly-budgeted project on time, supplying well-devised process engineering work which was independently verified by expert consultants. The cost-estimate was well supported with data from up-to-date cost indexes and Australian construction industry databases, and was amply detailed for the study purposes.
