Surface Mining Methods and EquipmentIntroduction to Mineral Deposit Models

After a mineral deposit has been discovered, delineated, and evaluated, the most appropriate mining method is selected based on technical, economic, and environmentally accountable considerations The first step in selecting the most appropriate mining method is to compare the economic efficiency of extraction of the deposit by surface and underground mining methods This section reviews .A mineral deposit model is the systematically arranged information describing the essential attributes (properties) of a class of mineral deposits The model may be empirical (descriptive), in which instance the various attributes are recognized as essential even though their relationships are unknown; or it may be theoretical (genetic), in which instance the attributes are interrelated.

Ore Deposits and Plate Tectonics

Ore Deposits and Plate Tectonics Plate tectonics, like crustal evolution, provides a basis for understanding the distribution and origin of mineral and energy deposits The relationship of plate tectonics and mineral deposits is significant on three counts: Geological processes operating due to energy released at plate boundaries control the process of mineral deposition Mineral deposits .Most vein deposits occur in fault or fissure openings or in shear zones within country rock A vein deposit is sometimes referred to as a (metalliferous) lode deposit A great many valuable ore minerals, such as native gold or silver or metal sulphides, are deposited along with gangue minerals, mainly quartz and/or calcite, in a vein structure A vein system is a group of discrete veins with.
