ORE DEPOSIT TYPES AND THEIR PRIMARY EXPRESSIONS
Ore deposits can be classified on the basis of: - • Composition of the deposit (contained elements). • Form of the deposit (size, shape, orientation and ore mineral distribution). • Associated host rocks or geological structures (ore associations). • Interpreted genesis of the deposit (processes, controls).
Jord | 50+ Years Experience across 105 Countries
Decreasing ore grades and depleting mineral reserves are no longer the only drivers behind the need to develop new technologies to process ore. Sustainable mining technologies provide economic, social and environmental benefits over the long term, overcoming negative impacts to land, air, water and local communities.
