The Mining Process. 1. Mining open pit and underground To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Mine wastes management Mining wastes is generated during the process of extraction, beneficiation and processing of minerals. Extraction is the first phase that consists of the initial removal of ore from the earth. This is normally done by the process of blasting, which results in generation of large volume of waste (soil, debris and other material).

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

Mar 02, 2016Open-pit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling. Open pit mining is used when the minerals to be mined are located just close to the

Ore production of magnetite was all from open pit mining through 1900, by which time more than 18 million natural net tons had been processed. In 1921 a three-compartment shaft was sunk beneath the open pit and in 1927 development was begun of an eastern ore body that had been discovered in 1919 by geophysical exploration.
