Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges.
Lesson 7.2: Mechanical Surface Mining Methods
Mechanical extraction methods employ mechanical processes in a relatively dry environment to mine minerals from the Earth's crust. In contrast, aqueous methods involve water, or occasionally other liquids, to extract minerals. The surface mining methods can be classified as shown here. We will discuss the mechanical extraction methods in …

The research involved the application of three-dimensional interpolation methods used for processing the data and the graphical representation.
The role of jigs in modern ore dressing
The jig is the oldest mechanical device for recovering heavy minerals from a lighter gangue. In the hard ore mining industry the invention of the table in 1893 diverted attention from developing the full potentialities of jigging through the screen for the recovery of finer particles of heavy and semi-heavy minerals and inter grown ...
Study of Metal Leaching from Ore Dressing Tailings
Mechanical activation of ores occupies a special place among methods of metal extraction, improving the indicators of processing processes [12–14]. Physical and chemical activity, solubility and activation energy of minerals depend on their dispersity and parameters of change in the crystal structure.
