Testing is vital to determine the amenability of an ore to separation by gravity. Sepro Mineral Systems strongly recommends testing with Met-Solve Laboratories Inc.

Please contact Sepro Mineral Systems or Met-Solve Laboratories before sending samples to determine appropriate laboratory tests for your material and quantity of material required.

A sample testing proposal will be issued prior to testing to ensure aspects of the test campaign are examined thoroughly.

Met-Solve Laboratories Inc. Laboratory Test Procedure

The sample test procedure is very straightforward. On average, if the water pressure and operational speed are correct for the material being treated, the Falcon Gravity Concentrator SB 40 produces about 100g of dry concentrate. Depending on the mass-pull required, for the given percentage of heavies that you would like to recover from the material, choosing the initial feed mass is very important.

There are two types of tests, one to investigate recovery into a very low mass (Falcon SB) and the other to investigate maximum recovery (Falcon C). A Falcon SB test is quite simple, where pulped material is fed into the Falcon SB 40 and the feed, concentrate and tailings are weighed and assayed to calculate recovery. More steps are required for a C test.

The multiple-pass C test allows a grade recovery curve to be drawn up that incorporates mass recovery. The continuous Falcon C technology is designed to pre-concentrate or scavenge metals and minerals from process streams and maximize recovery.

Falcon C Simulation

  • Recovery of free gold, silver or platinum from process streams.
  • Samples are usually from the milling circuit.
  • Mass recovery to concentrate is typically less than 1% of feed.
  • Produces a high grade concentrate.
  • Recovery of metals and minerals from process streams.
  • Samples are usually from tailing or feed streams i.e. scavenging or pre-concentrating.
  • Mass recovery to concentrate is cumulative; 10, 20 and 30%.
  • Produces a high recovery concentrate
