Sulphide Gold | Gekko

Sulphide Gold Recovery. Pre-concentration of coarse 350 – 500 micron sulphide-associated gold ore, using the InLine Pressure Jig, is required to reject gangue from the high value material. The IPJ, a classic pre-concentration device, is effective in gangue rejection prior to further processing of valuable gold-bearing material.

If the ore product contains a combination of coarse and fine free gold, the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higher-yield product. For ores smaller than 50 micron, the particle weight is too light for physical separation by gravity; therefore gold recovery will require a modular chemical flotation process.
