The whole mineral processing experience begins with metallurgical testing and at Nagrom we aim to make this an interactive encounter. Programs with progressive check-points and open discussion enable productive and cost effective outcomes.

Nagrom conducts ore characterization and circuit specification test work in the following areas:

  • Comminution (Jaw, Rolls, Ball & Rod Mills - Trommels)
  • X-ray Ore Sorting (Applied Sorting - Full Transmission X-Ray)
  • Drying (Rotary Kiln & Room Dryer)
  • Particle Size Distributions (Various Screens - Standard & Micro-spin Cyclones)
  • Gravity Separation (Spirals, Tables, Jigs, Centrifugal & Hydrosizer)
  • Flotation Circuits (Bench Unit & Certified Denver Pilot)
  • Magnetic Speciation (Disc, Drum & Belt Magnets to 20000G - Davis Tube Recovery)
  • Electrostatic Separation (Bench Unit & Pilot Scale)
  • Dense Media Applications (DMS Cyclone Pilot Plant [12mm] & Cone [to 50mm])
  • Gold Leaching Studies (Static & Agitated Programs)

Nagrom’s metallurgical expertise covers the following minerals:

  • Scheelite
  • Molybdenite
  • Zircon
  • Mineral Sands
  • Garnet
  • Tantalite
  • Columbite
  • Pyrochlore

Mineral Benefication

Nagrom’s history is all about specialty mineral beneficiation. Our extensive range of mineral processing equipment provides a turn-key availability to many metallurgical processes either on-site Kelmscott or containerised and shipped to your site.

A tailored solution will attend to:

  • Mineral separation and reconstitution to specific blend targets
  • Mineral species separation down to ultra fine particle size
  • Low magnetic and paramagnetic mineral species separation
  • Narrow band SG separation of minerals via Dense Media Cyclone
  • Preparation of primary concentrates for down-stream processing trials

Custom Processing

The total Nagrom experience can be applied to the custom processing field whether you have an existing process plan or just require delivery of a particular grade product.

Customised programs, short and long term or permanent at your site, are available for:

  • Drying - Batch & Continuous
  • Scrubbing Trommels
  • Crushing
  • Milling
  • Screening
  • Desliming
  • Gangue Separation
  • Gravity Classification
  • Magnetic Speciation
  • Electrostatic Speciation
  • Flotation concentrate production including scavenger & cleaner circuits
