Metallurgy Process, Definition with Examples | Types of Metallurgy

The process of separating gangues present in ores obtained from mines is called concentrating of ore. To concentrate the ore, firstly by separating large pieces of ore by hand. After this, they are broken into small pieces by handcuffs. These small pieces are put in the crushers. The crushers are like a millstone. Which consists of two plates.

gold | Metallurgy for Dummies

Gold is purified through a process of high temperature heating or chemical exposure, depending on the purity of the mined gold. If the gold is a low grade ore, then it is broken up into chunks that are then put in carefully lined pads and treated with a dilute cyanide solution, which dissolves the gold. Gold Coins
