Pilot Plant

A pilot plant is a reduced-scale facility used to carry out tests in a controlled environment before implementing a large-scale process. Our facility allows testing of the gravity separation technique with different types of materials.


Gravity separation comprises concentration methods based on differences in the density of different mineral species. These methods use gravity to separate particles of different density and, therefore, particles with different sedimentation velocities.


Within the extensive range of gravity methods and equipment available in this field, our pilot plant has three spirals and a shaking table. The combination of these equipment enables effective processing and concentration of a wide range of materials.

Classic examples of concentration:

  • Concentration of heavy metals (gold, silver, copper, lead, zinc, tin, tungsten, etc.).
  • Concentration of sulfides and/or iron minerals for purification of clays or feldspars.
  • Recovery of raw materials in industrial waste.
