What is hydraulic washing a method for?
· Hydraulic – Denoting or relating to a liquid moving under confined pressure Complete answer: · An ore of a metal is an impure source of the required metal, meaning that other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. are found in the ore of a metal which we collectively refer as gangue.

Enrichment of Ores | Learn Important Terms and Concepts
Hydraulic Washing – In this method, the ore is finely ground and washed with water. The passing water washes away the impurities that are lighter than the mineral. The upstream water passing through the ore takes away the lighter gangue particles leaving behind the heavier metal particles. This is a method of gravity separation.
