They are using flotation, metallurgy testing showed a decent recovery with gravity but a better recovery with flotation. Although in reality recovery was horrible below 60% This is mainly free gold, although it is very fine gold, as small as 10 micron size and the largest pieces being in the neighborhood of 500 micron.

Poor partition behaviour of the cyclone combined with upsets in the cyclone feed stream can is the most significant cause of reduced gravity gold recovery.

A standard ball mill may grind your ore to 75 microns. Fine grinding is one process available to liberate refractory gold. Gravity Recoverable Gold (GRG) refers to how much gold you can recover based on how fine you are grinding/milling your ore. The GRG (Gravity Recovery Gold) testing is available at Met-Solve Labs.

Transcript: We’re going to start here and first identify the different parts of a milling circuit when it includes a gravity circuit. So you’ve got your ball mill that’s doing the milling. You’ve got a pump that’s pumping into the cyclone and feed may enter here. Often it does. Feed may also just enter here into the start of the ball

Tests have shown that 95% of the gold in the silver chloride material can be recovered using the company’s gravity ball mill circuit. This work has already begun. These efforts accomplish two things for the company. First, this allows for gold recovery of highly assayed material at the bottom of the heap leach pad.

satellite deposit of high-grade gold mineralization was defined between 2009 and 2012. To support processing of this high-grade material, an 800 tpd mill with gravity and flotation concentrate recovery was built at a cost of USD$ 20 million. Production of underground ore began in Q3/Q4 2014, with name plate capacity achieved in Q1 2015.
