The i350 is a family member of the Falcon Gravity Concentrators Gold Mining Equipment which has revolutionizing the world of alluvial gold mining and dredging the same way its little brother, the i150, has impacted the world of hard rock mining. This is a gravimetric mineral concentrator that uses enhanced gravity (G's) to concentrate the 'free' heavy minerals.
In mineral processing or metallurgy, the first stage of comminution is crushing. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

How to Recognize Hard Rock Gold Ores. September 2017 by Chris Ralph. I regularly get inquiries along the line of: "Hey, I found this rock, and I think it might be gold ore. How can I tell?" Prospectors are always on the lookout for gold-bearing rocks that may be the source of any nearby placer gold.
The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in the leaching process.
