gravity separation circuit for alluvial deposit

Zircon Used as a gemstone and an ore of zirconium. Geology

Today, most zircon is produced by mining or dredging zircon-rich sediments. These sediments can be in beach, littoral, or alluvial deposits. Zircon has a specific gravity of 4.6 to 4.7, which is much higher than the typical detrital sediment grain that is between 2.6 and 2.8.

DEPOSITS OF PYROCLASTIC SEDIMENT GRAVITY FLOWS

There are two end-member kinds of pyroclastic sediment gravity flow deposits (1) pyroclastic flow deposits that are relatively thick, poorly sorted, commonly containing abundant fine-grained ash in the matrix (1/16 mm; 4 phi), and with crude or no internal bedding, and (2) pyroclastic surge deposits that are relatively thin, better sorted

Introduction to Paleoplacer Deposits Exploration Geologist

Mar 03, 2016Alluvial or eluvial deposits sometimes have the largest gold deposit and are very common. This deposit is created when a force of nature moves or washes the gold away, but it doesn't go into a stream bed. It contains pieces of ore that have been washed away from the lode. Alluvial deposits are the most common type of placer gold.
