In 1488, Ivan III sought to attract craftsmen who knew how to separate gold ore from barren rock. The first concentration plant for gold extraction was built on the Iset' River in 1748, and in 1763, M. V. Lomonosov provided descriptions of a number of concentration processes in his work The First Foundations of Metallurgy or Ore Processing.

Ore concentrate - Wikipedia

The raw ore is usually ground finely in various comminution operations and gangue (waste) is removed, thus concentrating the metal component. The concentrate is then transported to various physical or chemical processes called hydrometallurgy , pyrometallurgy smelters , and electrometallurgy where it is used to produce useful metals.

Ore deposits are crustal concentrations of useful elements that can be exploited at a profit. Like all crustal rocks, they consist of minerals formed by geological processes. There are four basic geological requirements for any ore deposit to form (Figure 1): - i) a source for the ore components (metals and ligands);

1. Ore Crushing: Ore comes from mines in lumps up to 1 m. across. The lumps are reduced in size in several stages: Primary crushing: – Here they break down to 100-200 mm. Secondary crushing: – Here they break down to10- 50 mm. Fine crushing :- :- Here they break down to, to 2- 20 mm or , and finally Grinding :- (if necessary), down to 0.05 mm. 2. Sizing: Every size of crushing follows by ...
