Mining Methods Boxhole Boring. Boxhole boring is similar to the raisebore method, but the drilling machine is located below the mineralization, so development is not required above the mineralization.From a drill chamber in waste rock below the ore, we drill a series of overlapping holes up through the ore zone and collect the falling ore from a chute in the extraction chamber.

What are the main methods of mining? | American ...

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Ore Dilution & Recovery in Mining

This method finds its best application for mining in heavy ground where the ore is high-grade and any loss or dilution is to be avoided, regardless of cost. By square-set stoping and close filling, high-grade sections of an ore body below or adjacent to lower-grade ore often can be mined without disturbing the lower-grade sections, which ...

ISR Mining - Uranium One

Conventional mining involves extracting ore from the ground and processing it to extract the target minerals. ISR (in situ leaching, also known as in situ recovery (ISR) or solution mining) involves using liquids (commonly referred to as "leaching liquors" or "lixivants"), which are pumped through the orebody while it is in the ground to recover the minerals from the ore by leaching.

Recovery of Copper by Solution Mining Methods

Solution mining is a mining practice that employs solutions (i.e. water or dilute acid) to recover a desired commodity from an ore deposit where it stands without also extracting the rock. There are essentially two types of solution mining: 1) in-situ and 2) in-place.
