Sample Testing

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

Please contact Falcon or Met-Solve 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 SB40 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). An SB test is quite simple, where pulped material is fed into the Falcon SB40 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 SB Batch Test	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
Test:	Test:
Minimum 10kg of sample. Single pass test. Assay tail and complete concentrate and back calculate the feed.	Minimum 1kg of sample. Three-pass test. Assay final tail, all three concentrates and back calculate the feed. Results yield a grade/recovery curve that incorporates mass-pull. Concentration ratio of combined concentrate should not exceed 4:1.
