I discussed your question with one of my process colleagues in order to get his input on separation of gold from black sands. It can be difficult to get a good separation as the black sands are quite dense. This is even more apparent when dealing with coarse sand and fine gold. I believe the i150 will be setup to run at a maximum speed of 50Hz.

The miller table is a gold separation device that consists of a flat sheet of matting inside a sluice, with water flowing over it. The black sand concentrate is dispersed gently at the start of the matting. The lighter black sand is then pushed down the matting, while the heavier gold stays where it
6.1. Magnetic classification of the Egyptian black sand heavy minerals 1- The magnetic recovery of the different Egyptian black sand heavy minerals at various magnetic field intensities was studied by Shevtsov et al. (1958), Hammoud (1966 1973) and Moustafa (1995, 1999, 2000 2003). The Egyptian black sand heavy mineral varieties

Jul 10, 2017 The black sand magnetite is a raw material to produce iron and steel. High content magnetite in the top meter beach sands of the north-west of El-Burullus Lake of Egypt is separated and mineralogically and geochemically investigated. Magnetite content obtained by laboratory techniques varies between 2.92 and 0.11 wt%, with 1.15 wt% average. It represents about one third of the total
The clean black sand and fine gold is added to the black sand fines obtained by dredging, sniping, or sluicing for final processing at the end of the prospecting season. At the end of the prospecting year (which for me is late October or early November), I have accumulated something between 20 and 40 pounds of black sand concentrate.
All separation, concentrate processing and melt testing conducted was from ... Most people travelling on the Churchill River notice the black sands. Local people tell stories of ... Development of a conceptual flow sheet and metallurgical balance.
Feb 04, 2008 The steel bar will help grind the black sands, and release any gold that is attached to the black sand. Run the tumbler for at least three hours. Once you have all the gold gathered, pan off the black sands, or use a magnet in a plastic baggie to retrieve the black sands, leaving only the gold-laden mercury and free mercury.

water slurry) is recommended for providing a good steady flow of feed material. This will relieve the mill operator of a tedious chore of a constantly changing concentrate line when hand feeding. Eight gallons of water per minute is considered minimum for black sands separation/concentration
STEP 7 Now, all that should be left is your fine gold, possibly some platinum, and a small amount of non-magnetic black sand. These final black sands can be separated by blowing lightly over them while vibrating the sheet of paper. Since the sand is about 4 times lighter than the gold, it will blow off the paper a little at a time, leaving the ...
